TPMS Light & Speedometer Errors in Chrysler T&C

Had the same issue with a 2011 Chrysler Grand Caravan. The tire pressure monitoring system showed persistent warnings despite correct air pressure in all tires. After proper diagnosis, it turned out the TPMS sensor batteries were depleted, causing false readings and sensor fault codes. The fix required replacing all four tire pressure sensors. This is actually a common issue when TPMS sensors reach about 8-10 years of age. The sensors contain non-replaceable batteries that eventually die. When this happens, the system cant properly monitor tire pressure and triggers warning lights. The repair involves dismounting each tire, installing new sensors, and reprogramming the system. Not a serious mechanical issue, but definitely requires professional service since special TPMS tools are needed for programming. The low tire warnings and speedometer errors cleared immediately after the repair. Worth noting that driving with failed sensors wont damage your vehicle, but you lose the safety benefit of tire pressure monitoring. Best to have all sensors replaced at once since theyre likely the same age and will fail around the same time.

Thanks for sharing your experience with the TPMS sensor replacement. I had a similar TPMS issue with my 2014 Town and Country last summer, the sensor fault warnings were driving me crazy. Mind sharing how much you ended up paying for the full sensor replacement? Also curious if the tire inflation warnings came back at all after the fix? My mechanic mentioned something about possible air valve corrosion that could cause recurring problems, but I want to hear about your long-term experience with the repair.

I had all the TPMS work done at a certified shop, total cost was 280€ for diagnosing and replacing the faulty sensor battery. Much cheaper than I initially feared. The tire pressure sensor fault cleared up completely after the fix and hasnt returned in the past months. While your mechanic raises a valid point about air valve corrosion, my issue was purely related to the depleted sensor battery. Regular tire pressure checks with a reliable pressure gauge show the system now works perfectly. The speedometer errors and warning lights disappeared right after the repair. One tip: after any TPMS service, its worth doing a thorough tire inflation check to ensure the system calibrates correctly. This helps confirm all sensors communicate properly with the vehicle computer. Its been about 6 months since the repair, and the system has worked flawlessly. No more false warnings or tire pressure monitoring issues. If youre seeing repeated problems, definitely have them check those air valves, prevention is better than dealing with recurring faults.

Following up on my initial concerns, I finally got the TPMS issue resolved at my local shop. The total repair came to 320€ which covered replacing all four tire pressure sensors. While slightly higher than expected, it was worth fixing properly. The mechanic confirmed the original sensors had dead batteries causing the constant warning lights. The entire job took about 2 hours since they had to dismount each tire to install the new sensors. They also performed a complete tire check and system reset. After 3 months, no more false low tire warnings or speedometer errors. The TPMS now gives accurate readings and the dashboard is finally clear of warning lights. The air valve stems were also inspected and showed no signs of corrosion. For anyone else facing similar problems, dont waste time repeatedly checking tire inflation like I did. Get the sensors tested if your vehicle is around 8-10 years old. These systems are great when working properly but require professional diagnosis when they act up.
