Hi The light will only come on if a sensor is missing damaged or at an incorrect pressure. It will relearn a sensor (if it&8217s been replaced or wheels moved front to rear) after a 20 minute stand. If the pressures are correct then I say a sensor have been damaged fitting the tires. If you have different wheels on with no sensors in the wheel the dealer can turn off the TPMS. Regards Merlin
Dont overlook the spare
No on the sensors. For Chryslers I believe theyd have the metal valve stems my 11 Avenger does. Pretty sure vehicle pre-dates common use of tire pressure sensors.
2004 I dont think it should either. Even in 2005 where a lot of SUVs had them mine didnt. I think the Limiteds had them but the Sports did not. If you do not have the short aluminum valve stems and no TPMS light on then you dont.
Thats weird ... maybe introduced mid stream My 05 has TPMS although it was manufactured in August (04)
Another thing . . I read somewhere on this forum that a guy replaced one of these sensors with an after-market part and still got the code . . then used a jeep part and the code didnt come up. It also said that jeeps dont like after-market parts much . . is there any truth to this
Uhh.....have you seen jeeps lately They LOVEEEE after-market parts. But Im not sure about after-market engine stuff so I cant really help there. Im not sure if when they replaced my sensors if they used after-market or OEM.

An unhappy jeep is one that is neglected and called a Car. I would apologize to your jeep once you get to the shop. It may seek revenge .

If it werent for bad luck Id have no luck at all... RANT Recall from earlier messages... After one nasty dealer experience I head to another and I get the vehicle I wanted but its missing the skid plate group and has the wrong wheelstires (it had the Chrome 17s I wanted the silver 16s). So the dealer agrees to swap the wheelstires for the ones I wanted and add the skid plate group. What I actually get is the 16 wheels I wanted and the Eagle RS-As although I asked for the Wrangler SR-As. Ok so I cough up a few extra bucks for the SR-As no biggie (315 CAD). I get home and check it all over. Skid plates all there... no tow hooks up front I return ask and get you just asked for the skid plates not the hooks. I know full well I asked for the skid plate GROUP I recall reminding the dealer NOT to order the rear hook cuz the hitch takes up the bolt holes and he agreed saying yep I know that already. So I ante up a few bucks for the hooks (180 CAD) which have arrived twice wrong first was TJ hooks then a single hook... mightve been the rear hook I gotta go back tomorrow for the third try. I realize in the wheel swap from 17s to the 16s they forgot to swap the pressure sensing valve stems that are part of the 28G package (on the Limited in Canada). So back I go to the dealer again and get told the steel valve stems go with the chrome wheels (as an appearance item that way everythings chromesilver) and they do NOT go with my overhead console. I asked for clarification on this matter since the Tire Pressure sensors are cleary stated on the window sticker as part of the overhead console NOT the wheel packages. I was told they will contact Chrysler and let me know (5 stems 250 CAD). So after putting up nearly 40k for this vehicle Im getting nickeled and dimed to death which to date might run me 750 CAD more than I originally thought (depends on the outcome of the valve stem issue). I thought this purchase would be much simpler than this I run my fathers business and I can tell you if I made it THIS difficult for my customers to be pleased Id have no customers at all. Im ok with paying for the tires and the hooks arent too much to ask Im sure Ill have fun installing them and that will smooth over my anger (I love modding anything and thats sorta modding) But the valve stems have my anger piqued. Theres no way Im handing over 250 for them theyre part of the vehicle I purchased and Im not taking no for an answer no matter how high I have to pursue this. I hope I dont have to get nasty in this situation but it might very well end up that way it doesnt seem that people respond to anything else nowadays. RANT Needless to say the local autoparts store (Crappy Tire for all you Canucks) got in my drop-in K&N filter today (a day early) so I might get that done on Saturday (all of 20 seconds) Modding... nope Im not addicted at all Unfortunately thats probably the only mods Ill be doing to the liberty unless you count winter mats.
Quote Originally Posted by 4Factor Unfortunately thats probably the only mods Ill be doing to the liberty unless you count winter mats. Sorry for all of your woe. Only one suggestion. Put everything in writing at the time. Even if it is only a notation to yourself. Date it and then constantly refer to your notes (even pointing to them when speaking to the dealer). They are much less likely to weasel
holding them to it. I figured letting them know exactly what I wanted would be enough since we sat and talked about what needed to be switched and added on two separate occasions and I was assured it was all going to be as requested you can understand why Im a bit disappointed that theyre throwing the it doesnt say that on the contract back at me. In fact if you look at the contract it says 2004 jeep
Dealers can usually order or sell you a pigtail end for the harness that will have a new connector and wires coming out of it. Then you can make the repairs as needed. Find a Chilton manual etc and verify the wire coloring to make sure the sides were switched. Also do not simply use crimp connectors for the repair. Due to the low voltage signals O2 sensors produce crimp connectors do not provide a
Your exhaust hanger not a clue get under the jeep look for every place something holds the exhaust up and check it and anything bolted to it.
The 16 Patriot wheels are also steel and have the sensors from the factory. Many similarities between the MKs and KKs in that area. Here is a write up on it. httpwww.jeepforum.comforumf98tpm-sensors-741251

Most likely a pattern failure. Without looking with a scan tool at the O2 sensor readings and fuel trims you really will be limited to trying the sensors. NGKNTK Denso or Mopar sensors should be used. Bosch sensors are a different design and perform differently. Most car makers are shying away from the Bosch design they just dont cut the mustard anymore.
The OBD indicated that 3 of the 4 sensors were at fault so I did some research to find out if I could test these sensors and I found that you could test them in the vehicle or take them out to test. I opted to remove them I connected my DC meter as instructed and heated the sensor with a blow torch as instructed and view the readings on the meter. The meter readings indicated that my sensors were not

Well I am totally lost for answers I reset engine light and of course it came back on but when I read the code it only showed fault with one of my O2 sensors (P0136) bank 1 sensor 2 so I did an in vehicle test and it seemed to be working as far as I understood how to test. I then reset the engine light and it came back on this time indicating the following codes (P0031005101360158 & 0300). So my question

Yes there are 02 sensors after the cats. Not sensors after the muffler.
Upstream O2 sensors are closest to the engine. Downstream sensors are after the cats. No need to splice wires you just need to either pull the correct sensor or take the one back to the store and exchange it.
Usually the upstream sensors have different plugs than the downstream sensors so that they cant be mixed up. Its also possible the kid behind the counter gave you the wrong sensor. Whats the part number on the box
