TPMS Warning Persists Despite Correct Tire Pressure

Had the same TPMS warning issue on my 2010 GMC Sierra. After proper tire pressure checks confirmed correct air pressure in all tires, the warning persisted. The problem turned out to be a failing battery in one of the TPMS sensors. These sensors contain batteries that typically last 5-7 years. When they start failing, they send incorrect signals or stop communicating entirely with the control module. Regular tire inflation and pressure checks will not resolve this since its an electronic issue, not an actual tire pressure problem. The repair required replacing all four TPMS sensors since they were all from the same production period and likely to fail soon anyway. Not a serious mechanical issue, just an inconvenient electronic fault that affects safety monitoring. The procedure involves dismounting the tires, installing new sensors, and reprogramming the TPMS module to recognize the new sensor IDs. A shop with proper diagnostic equipment needs to handle the programming part. While you can drive with failed TPMS sensors, you wont get accurate tire pressure warnings, which could mask actual low tire pressure situations that need attention.

Thanks for sharing your experience. Dealing with similar sensor fault problems on my Savana right now. Getting false low tire pressure warnings despite proper tire inflation levels. Thinking about replacing the TPMS sensors since the repair worked well in your case. Quick questions: Do you remember roughly how much you paid for the full sensor replacement and programming? Also, has the TPMS system given you any other trouble since getting the new sensors installed? Just want to get an idea of costs and reliability before heading to the shop with my air pressure warning issues.

Good news on the TPMS issue fix for my Sierra. Following up on your questions about costs and reliability, I recently had the sensor battery replaced and TPMS fault resolved for 280 Euro total at the shop. The tire pressure monitoring system has worked flawlessly since the repair, with no false warnings or sensor communication problems. The fix addressed the root cause of those persistent low tire pressure alerts that kept appearing despite proper tire inflation. A proper TPMS diagnosis showed it was indeed just the sensor battery failing, not a more complex system fault. The repair process was straightforward, no need for full sensor replacement in my case since only the battery was depleted. The mechanic confirmed all other TPMS components were functioning correctly after the battery swap. Based on my experience, if your tire pressure sensor fault symptoms match what I described, getting it checked soon is worthwhile. Driving with malfunctioning TPMS means you could miss actual low tire pressure situations requiring immediate attention.

I finally took my Savana to the shop after getting that helpful advice about TPMS issues here. Just wanted to close the loop on what happened. The mechanic confirmed it was indeed failing TPMS sensors causing those false air pressure warnings. Had to get three sensors replaced since their batteries were dead. One sensor was still working fine. With parts and labor including the TPMS reprogramming, the total came to 320 Euro. A bit pricey but worth it to get rid of that constant warning light. The tire check and pressure readings are now accurate on all four wheels. No more false alarms popping up on the dashboard. The air valve stems were also replaced as part of the service since they were showing wear. Quick tip for others, get your pressure gauge readings checked against the shop equipment. Mine was off by quite a bit which added to the confusion early on. Really glad I got this sorted before any actual tire pressure problems occurred. Thanks again for the guidance. The repair was exactly what was needed to fix those annoying TPMS warnings.
