Faulty TPMS Sensors Causing False Caliber Tire Warnings

I had a similar TPMS issue with my 2013 Dodge Avenger last year. As someone with some experience working on cars, I initially tried resetting the TPMS system using the dashboard menu, but the warning light kept coming back despite correct air pressure in all tires. After checking each tire with a reliable pressure gauge multiple times, I took it to my regular workshop. The diagnostic revealed that the sensor batteries were depleted, which is a common problem on these models after about 8-10 years. The TPMS sensor fault was triggering false low tire warnings even though the tire inflation was perfect. The total repair cost was 280€ for replacing all four sensors. The workshop mentioned this is a typical lifespan for original TPMS sensors, and the battery is not separately replaceable, the entire sensor unit needs switching. What year is your Caliber exactly, and have you had any previous TPMS repairs? Also, when was the last time the sensors were replaced? This information would help determine if you are facing the same sensor battery issue I encountered. The repair solved all false readings completely, and the system has been working perfectly since then. No more unusual tire pressure warnings on cold mornings.

Thanks for the detailed response. My Caliber has 109771 KM and had its last service 3 months ago. The mechanic confirmed all TPMS sensors were original, which explains the sensor fault issues. Getting similar quotes around 280€ for a complete sensor replacement. The air pressure readings from my manual pressure gauge show correct inflation, but the system keeps triggering false low tire alerts. Planning to replace all sensors next week since they are clearly at end of life after 12 years. Will update once fixed.

You are absolutely right about replacing all TPMS sensors at once. After my sensor replacement on the Avenger, the tire check system has been flawless. The false low tire warnings completely stopped, and the air pressure monitoring works exactly as intended. One tip from my experience: make sure the workshop properly initializes the new TPMS sensors after installation. Some shops skip this step, which can lead to ongoing TPMS issues even with new sensors. The initialization process ensures proper communication between the sensors and your vehicle's computer. Since your Caliber still has the original sensors at 109771 KM, you are definitely making the right call. The 280€ price is standard for a complete set, that is exactly what I paid. The repair should resolve those frustrating false tire pressure warnings you are getting. The tire inflation values may be correct on your manual gauge, but those aging sensors simply cannot transmit reliable data anymore. A full sensor replacement will give you peace of mind and proper air pressure monitoring for another decade.

Based on the tire pressure monitoring issues with my 2011 Caliber, I am going to proceed with the full TPMS sensor replacement. The constant low tire warnings despite proper tire inflation levels are clearly caused by the original sensors failing after 12 years. The 280€ quote for replacing all air valve sensors matches what others paid for similar repairs. The sensor fault seems common on these older models where the TPMS batteries are depleted. My manual pressure gauge confirms correct tire inflation, but the aging sensors keep triggering false alerts. Will make sure the shop properly initializes the new sensors during installation to prevent any communication issues with the system. Good to know this fix worked well for others with similar symptoms. Planning to have all sensors replaced next week since waiting longer just means dealing with more incorrect tire pressure warnings. Will post an update once the repair is complete and the system is properly monitoring tire pressure again.
