JEEP WRANGLER I YJ 92 wrangler temp sensors and gauges

92 wrangler 2.5L 5 speed manual. the only gauge not working is my temp gauge inside the cab. when i went to the local parts place they are telling me there could be sensors in the head or block etc etc. the only sensor i found and i guess care about is the one related to temp round gauge in the cab. this is the 2 wire sensor that screws into the thermostat housing. is this the only one is there something

something else im missing I did check the voltage while the truck is running and reading almost 5 volts i cant remember like 4.89 or 4.97 something like that. so i guess the voltage its good if that is the right sensor for the gauge in the truck im guessing i would just be able to replace it and it will be all good again right As previously mentioned there are a total of 2 temp sensors on your jeep

JEEP WRANGLER Need to replace O2 Sensors please help

I searched the first 3 pages of results for How to change o2 sensors and O2 sensor tj 4.0 but to no avail did i find anything that truely got down to the nitty gritty to answer my questions. Basically because no one else asked the right questions nor supplied sufficient info and mostly got flammed for such. So the story... My wife drove the jeep to ORiellys the other day because the CEL came on and

JEEP WRANGLER o2 sensors

Ok here it is. I have a 1997 jeep wrangler 2.5. I have replaced about 10 bank 1 o2 sensors. . I read on here about a guy who tried the orginal mopar so i tried that it worked longer then the boschs. But now it is out. I have replaced my cat because it went out because it ran to rich and burnt it up. I have replaced my intake exhaust gasket. I have no clue why it is going thru all of these o2 sensors.

JEEP WRANGLER II TJ 02 Sensors wont ready Codes after replacing 02s Read and try this.

So Ive been chasing down an issue with the o2 sensor heater on my 06 LJ for awhile now. I keep getting the p0153 code and a CEL. This error code is 21 Oxygen Sensor slow response. It comes and goes intermittently sometimes the CEL comes on sometimes it doesnt. Ive gone through the o2 sensor wiring harness looking for shorts Ive checked for exhaust leaks Ive tightened up the flanges at the mini cats

and then replacing the one still throwing the P0153 with another NGK and returning the first one I tried this. My code never came back and my 02 sensors finally readied up. I have no idea why mine decided to start having this problem after 76k. To quote from another forum where this was discussed Quote Ive done this on two different 2005 wranglers- both also threw codes (different codes for both jeeps).

JEEP WRANGLER Parking Garage - Sensors not detecting Jeep

Hey guys.. havent run into this issue yet but curious as to if Im alone in this. Went to the airport today to drop off the GF and I pulled up to the gate to get my parking ticket. Well I pushed the button to have it dispense my ticket nothing happened. I pushed the intercom and the person on the other end told me that some vehicles dont trigger the sensors to let the system know a vehicle parked there

Its none of the above suggested reasons. Our wranglers have heavy cast iron axle housings and massive amounts of steeliron within a short distance from the street. Commercial trucks even have their axles up even higher with big tires. Those sensors are not magnetic they are just like metal detectors you look for junk at the beach with and they would have less trouble with a jeep than most cars. Far

JEEP WRANGLER II TJ 2001 O2 Sensors in a 2003...

Ive known that my gas mileage was going down for a couple of weeks now and I suspected that Id soon get an O2 sensor code of some sort. Well today I got a P0171 code and after finding no vacuum leaks (2 cans of starting fluid soaking the top half of the engine ) and no other sources of the lean condition I decided to swap the upstream O2 sensors front-to-rear. If the front upstream sensor itself was

JEEP WRANGLER aftermarket wheels for 08 w pressure sensors

I was going to order a new set of wheels and tires before my new 08 comes in. Then I realized that the 08s will have pressure sensors on the wheels. From what I understand about the sensor they are mounted to the wheel at the valve stem. I assume that this can be removed and mounted on the new wheels. Can anyone confirm this

The wrangler doesnt care where the wheel is only that

JEEP WRANGLER Downstream O2 sensors causing pinging

Ok got kind of a weird one here. 2001 TJ 4.0L auto 122000 miles Been getting a check engine light for over a year now. It was for one of the cats being below threshold (P0420 if I remember correctly). jeep had no symptoms of any kind same power and gas mileage as ever before. Based on this I replaced the downstream O2 sensors and the code has been gone for 100 miles (it had gotten to where it would

JEEP WRANGLER II TJ 02 sensors 04 I6 wrangler

Hey guys Im going to replace my 02 sensors and was told by advanced auto I have two of them an upstream and a downstream... I called Nappa up and they told me they show 4- 02 sensors for my jeep I run into problems all the time with parts stores giving the wrong parts and what not. Can anyone confirm this My jeep will not hold an idle for more then 5 minutes and when driving down the road it violently

Im not sure which code it is throwing now. I had a chrysler neon a couple years ago that did exactly what my jeep is doing it threw a cam sensor code when this happened but in the end it ended up being the 02 sensor and an 02 sensor code was never shown. My jeep last week threw the cam code so I replaced it and it did nothing the problem is now worse. So I am thinking of just going ahead and replacing

1 it should be extreamly easy to tell how many O2 sensors you have. A pre 1997 there were only O2 sensors before catalytic converters. It doesnt matter what car or jeep you have. 1 cat-1 O2 2 cats-2 O2s. B in 1997 the EPA required conversion to OBDII that reqires O2 sensors before and after the cat so 1 cat 2 sensors and 2 cats 4 sensors. 2 to be sure you can always count. O2 sensors are very easy

JEEP WRANGLER OEM O2 sensors What brand

OK so I know the factory O2 sensors are Mopar but Im fairly sure that Chrysler subcontracts the sensor production. Who makes the OEM Mopar O2 sensors It seems like we could all get the same quality and save a few bucks by buying the correct O2 sensors from the manufacturer and skipping the Mopar markup. If you are about to replace your OEMMopar O2 sensors look at the newold sensors and see if there

from rockauto.com for about 13 of what I assume is the same sensor with the Mopar bag costs. My point of this thread is to see if others are willing to examine thier O2 sensors and post up the markings on the Mopar sensors they have. Maybe we can crack the code buy the same quality factory parts without the factory premiums. You can get Mopar sensors from Mopar Parts for Dodge Chrysler and jeep

JEEP WRANGLER O2 Sensors

Coded out a couple months ago for O2 sensors. I bought a complete set from Auto Zone (Bosch) and got them replaced. Here it is only two to three months later and the same code is back. The strange part about this If it is cold snowing or raining my engine light does not come on (thought it was a vaccum leak this whole time). Head home in the afternoon sun and engine light immediatley comes on. Had

For whatever reason jeeps are sensitive to the brand of the O2 sensors. The OEM sensors were NTKNGK which are readily available in the aftermarket. The vehicle was originally calibrated around NTKNGK sensors not the Bosch sensors so variances in the milivolt range are enough to potentially set a fault. Personally Id replace them all with NTKNGK sensors from Rockauto or wherever else you choose to source them.

JEEP WRANGLER Airbagf sensors in bumper

Looking to changing factory front bumper but I need to know if the airbag sensors are part of the bumper or in the frame. Thanks

There are 3 or 5 impact sensors in a JK. The first one is in the Occupant Restraint Controller which is mounted on the the transmission tunnel under the center console rearward of the gear shift lever. This is the main brain for the airbag system. There are 2 more sensors mounted in the engine compartment just below and inboard of the headlights one on each side of the vehicle. If you have side mounted airbags there are 2 more sensors one mounted on each B-pillar (the ones rearward of the front doors). Thats it. Whoever says there are airbag sensors in the bumper just doesnt know JKs. Some vehicles do have them there. I think my 99 Chevy van does but the jeep doesnt.

JEEP WRANGLER II TJ O2 Sensors 2001 (4) vs 1999 (2)

I am replacing my 1999 4.0 with a 2001 4.0. Question The 2001 has 4 - O2 sensors. I believe the 1999 only has the two. The 2001 motor came out of a Cali. jeep. How do I need to connect to the O2 sensors from the 2001 motor with my 1999 wiring computer Can the two upstream and two down stream sensors be wired in series The 2001 motor came with a brand new header and exhaust. I would like to be able to use this exhaust if possible. Confused on how to handle this. Any help would be appreciated.

However the actual Mopar part numbers are very different if I look at different websites. Dealer wont tell

JEEP WRANGLER II TJ 2000 2.5 o2 sensors both disconnected

Hi guys...I bought a 2000 4cyl and the PO put a pace setter header back exhaust on it. I found the front o2 wire cut so I started looking for the rear and they did a straight pipe with no cat and no second o2 at all...my question is what does the motor do with no readings Does it lean it out or default to a richer fuel mixture Im hoping the second Im already looking for a stock cat plus back system

straight pipe was probally for noise making purposes. without the cat you are obviously letting more pollutants into the air and actually decreasing efficiency. keep an eye on the header- those are prone to cracking. make sure you have good motor mounts. also now might be a good time if you have the to replace both o2 sensors. NGk is the preffered brand i have tried bosch in the past but the jeep

JEEP WRANGLER Need O2 Sensors

This may have been covered in previous posts but the catalytic converter is rattling in my 97 TJ 2.5L. Im guessing this is what has been causing the really poor performance. Im about to replace it with a Walker direct fit Cat and an MBRP Cat Back exhaust (the exhaust on it now is rusted out). My question is because Im replacing these things will I also need to replace both the upstream and downstream

If your O2 sensors were going bad youd notice a lot of black carbon around the rear of the jeep where the exhaust exits. Which says your running rich and therefore having really crappy mileage. Whats the mileage on the jeep The recommended replacement of the O2 sensors is around 100000 miles if memory serves me correctly. When you do them recommend doing both since then both will be new and not trying

JEEP WRANGLER O2 and other sensors

03 wrangler TJ 2.4 ltr 52k mi. When should you change out the O2 sensors pre and post cat. Also the throttle position sensor and are there any other sensors to check or change. Would anyone recommend a hand held diagnostic tool or laptop up link for reading soft codes...my assumption is that hard codes make the engine light come on. If you have had success with one of these tools let me know the model and cost. Thanx

JEEP WRANGLER Tire pressure sensors

My tires and wheels are mounted already and if I change the stock to the new tires I know I will get a light on the dash because the sensors are missing.

JEEP WRANGLER Camshaft & Crankshaft Sensors failer- again

(First of all I know there are several good posts for these problems- Ive read them all several times now but none have helped my current problem.) So I got the Camshaft and Crankshaft sensor codes (0340 0320 1391) no problem replaced the units and the engine light turned off on its own and all is good. (the camshaft sensor was replaced last year when I got a code also). Today I actually felt the slipjump

Well I spoke too soon. I went for a little longer drive after installing the mopar sensors and the check engine light came on this time only the 0340. Ive read the other threads on crankshaftcamshaft sensors and it seems some people cant get their codes to clear either The jeep is running fine (it seems) no slipping or stuttering like before. I cleaned the connections pretty good when i installed the new sensors so im kinda stumped. Would love to hear some more opinions.

JEEP WRANGLER III JK 2012 JK not triggering traffic sensors

Ive had to make two bad turns at stop lights because the jeep would not trigger the light. Wtf Is the engine block aluminum This isnt every time or every light. Anyone else

if your jeep is stock then the problem is the traffic sensor. My built XJ had issues triggering sensors 2 sensors but that was with a 7 lift 35 tires and aluminum wheels. One of the sensors was replaced and the new one works fine now.

JEEP WRANGLER III JK tires sensors question JK

what happens if you change wheels and tires with NO tire pressure sensors Does the earth stop spinning

each individual tire. This brings a question to mind and that is are these devices addressed in other words is the left front sending unit programed to be just that a left front sending unit. If so what happens when you rotate tires. Are they automatically readdressed to the new location some how. After a rotation you usually have to re-learn the sensors. Since I do not have this function in my jeep

JEEP WRANGLER II TJ 02 TJ 4.0L... O2 sensors

A few days ago I got the following codes P0135 P0155 P0161 I cleared the codes and they havent come on in 150ish KM now. I have noticed my MPG has dropped quite a bit (since I did a roof light bar that is) as I was able to get 350ish to 400ish KM to about 45 liters but now I get about 250ish KM to 45 liters. At first I thought it was just the light bar but with these codes Im thinking its my O2 sensors.

JEEP WRANGLER Testing O2 sensors

My 2001 TJ is telling me that my main catalyst bank 2 is performing below specified efficiency levels. Looking at a scan tool I have I see that the post-cat sensor for bank 2 is running lower voltages on average than the other 3 while the jeep is at idle. I think (and I know that is dangerous)... I think this could mean that either the catalyst is bad and this is the reason for the lower voltage...

The Factroy Service Manual has complete diagnostic testing and repair procedures for every part and system on your jeep. They are well worth the cost to acquire. For the 4.0L HO OBD-II the O2 sensor has 4 wires. One wire is the 12-14 volt power that comes from the O2 sensor heater relay on the passenger side firewall (unless they moved them in later years to the relay & fuse boxes) and that powers

JEEP WRANGLER Bosch O2 Sensors

Im going to replace my front O2 sensor and am considering using a Bosch OEM style (no splicing) sensor. I found some threads where it was said that the Boschs are fine on OBD I cars and not on OBD II cars. Is stock really better or do the Boschs work fine

than for them but then its hard to tell for certain. I personally have decided against Bosch just because of the volume of complaints in general. Something good wouldnt have quite that many complaints. If you can afford OEM sensors Id say to go with those just for the peace of mind. Bosch doesnt seem too reliable in the O2 sensor group but there are several other makers of O2 sensors for the jeep

JEEP WRANGLER Help with gaugessensors

A couple questions on my gauges and sensors. First on the temp gauge I originally could not get the temp over 100 degrees and had no heat but did have a fan. I figured the t-stat was bad so I replaced it. Now I have heat but the temp still never shows over 125 deg. I know the engine is heating up but Im still showing this low temp on the gauge. im thinking either the sensor or the gauge is bad. Is

the resistance while the sensors are installed and the vehicle is running. Is that correct. I assume you take the reading with the vehicle running and whatever the gauge is reading at the time you correlate that with the ohm reading on the charts. If the ohms are out of those specs then that s a bad sensor Thanks again. I saw on the link you provided that the poster had everything working on his jeep.

JEEP WRANGLER o2 sensors keep going bad

A couple months ago my camshaft position sensor in the distributor went bad. For a few days my engine was running extremely rich and was blowing out a lot of thick smoke. Now my o2 sensor is either being lazy or just failing and I was wondering if all that smog from my bad CPS might have clogged it up This will be my 3rd time changing my o2 sensor this year and Im trying to figure out why they keep going bad.

stock minus the CPS and o2 sensor. Just saying silicone can kill an 02 sensor. I was only thinking like perhaps if you regularly used silicone in your garage for other stuff and it coul have been out producing fumes when you replaced your previous 02 sensors. Youve confirmed you arent a big silicone user so that wouldnt be it. There are some non-02 sensor-safe products some people add to their jeeps

JEEP WRANGLER O2 Sensors the same

I have a check engine now and its pointing to the rear sensor problem is I replaced it two years ago. Its on one day then off the next so its just on the threshold. Im wondering if its the sensor or the cat (no rattling noticed). Can I swap sensors to determine the problem Are they the same part

If you mean swap sensors with one of the other 02 sensors in another location on your jeep I dont think it would work. Most of them have unique plugs so you cant mix them up when installing them.
