2014 tpms

[Jimdeja]

I had snow tires put on rear. Now left side shows 1 in tpms. All others show proper pressure. Any ideas?

They ruined the sensor. Time for a new one.

Is this something I can change myself or does the dealer have to do it?

Thanks.

You will have to break down the tire. Also, you have to be very careful with the mounting nut so as not to strip the stem threads. Then you will have to "learn" that sensor for it to work properly.

Does the sensor really need to learned? My 2012 Compass accepted them without any to do. Fix and Forget.

Does the sensor have to be purchased from Dodge or just at an auto parts store?

Each sensor's (transmitter) broadcast is uniquely coded so that the wireless control module (WCM) can monitor the state of each of the sensors on the four rotating road wheels. The WCM can automatically learn and store the sensor's ID while driving "within 10 minutes continuously above 15 m.p.h. (24 Km/h)" after a sensor has been replaced. The vehicle must be stationary for more then 20 minutes in order to initiate the learning sequence.

The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location. (LEFT FRONT, LEFT REAR, RIGHT FRONT, and RIGHT REAR) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for "Program Tire Pressure Sensor ID w/ TPM Tool" under "MISC" for the "WCM/WIRELESS CONTROL MODULE".

Either way, it has to be learned because each sensor has a unique ID.

Good luck.

Sounds like this is above my "toolbox pay grade". Dealer, another more informed tire store, or just pick up the part and put it in?

You can do it. Like I said above, after install, without the programmer, the vehicle must be stationery for 20 minutes and then go for a drive and it should learn it. Why not let the guys that broke it fix it. If they broke it, they should replace the part. I don't know if you broke it or a tire store, but under the NHTSA law regarding TPMS, there is something called "make inoperative". In a nutshell, if the TPMS has been made inoperative, the car or truck is not supposed to be put back in service until the TPMS is working correctly. It is now illegal to make a TPMS inoperative.

Read this, especially #3 on page 2.

Soooooo, if you go to a dealer and drive in and they check the system (believe me they do), and find that a sensor is bad, they can keep your car until it is repaired. How do I know they check and what they will do? I took my wife's Jeep in for a transmission fill tube replacement under warranty. I got a call and the service manager informed me that one of the tires was 1 pound lower than the other three. 1 pound. He stated that he had to bring that to my attention and wanted to know if I wanted them to correct the problem. I informed him that I don't count on the TPMS for accurate tire pressures. I use a gauge. So they check the TPMS when it comes in and supposedly, after any repairs or service has been made to the car/truck, they check it again with their scan device (not the scan tool but the IPAD looking thing they use when checking in a vehicle for service.) If it is taken to a tire store, they are under the same obligation to verify the TPMS is fully functional before and after all tire work is done.

WOW! Thanks for the info. I checked with my dealer (an honest one) and he thought since the sensor is reading 1 instead of dashes or flashing that it just needed to be reset. He said try Walmart if driving it doesn't bring it back to life.

Thanks again for your in depth explanation!
