Cherokee TPMS Sensor Issues: Causes & Repair Guide

Thanks for sharing your experience. My Cherokee just hit 188105 KM last week after regular service. The TPMS issue on my vehicle seems different from yours. After the digital diagnostic, it showed the rear right sensor was sending erratic signals despite proper tire inflation. The manual pressure readings consistently show 35 PSI, matching factory specs. When checking the fault codes, the system indicates intermittent signal loss rather than a simple battery issue. Think I will need a complete TPMS sensor replacement rather than just recalibration based on these symptoms.

Thanks for the additional details. Since my Cherokee repair, I have learned more about these TPMS quirks. Your case with erratic signals from the rear right sensor points to a different issue than what I faced. The intermittent signal loss you mentioned often indicates electrical interference or physical damage to the sensor unit, not just a battery problem. When running my diagnostic tests last year, signal loss patterns usually meant the entire sensor module needed replacement. A few key observations from owning the same model: Erratic signals typically worsen over time, Tire pressure readings become more unstable in cold weather, Fault codes persist even after a proper tire check and inflation Based on my repair experience, I recommend: 1. Full TPMS sensor replacement for that specific wheel 2. Complete system recalibration after installation 3. Clear fault codes from memory The repair cost should be around 150-200 Euro for a single sensor replacement with programming, significantly less than replacing the entire system. For future reference, document the fault codes. They help track if the issue spreads to other sensors, which happened in several cases on our model year Cherokees.

Thanks for the detailed explanation about TPMS sensor issues. Just had my Cherokee serviced, and you are right about the signal patterns. The intermittent fault codes from my rear right sensor definitely suggest a complete unit replacement rather than just recalibration. The tire pressure consistently reads 35 PSI with my manual gauge, but the erratic TPMS signals persist. Your cost estimate of 150-200 Euro for a single sensor helps with my repair planning. Will schedule the replacement next week. One question on your point about cold weather, have definitely noticed more frequent warnings during temperature drops. The fault codes remain stored even after doing a proper tire check with a pressure gauge. Does this align with the sensor deterioration pattern you mentioned? Based on what you described, I should probably document these fault codes in case other sensors start showing similar issues. Getting ahead of potential problems with the remaining TPMS sensors seems like smart preventive maintenance.

As someone with some experience working on similar models, I dealt with this exact sensor fault on my 2019 Cherokee diesel last year. The TPMS issue showed identical symptoms, constant low pressure warnings despite correct tire inflation. After using a pressure gauge to verify all tires were properly inflated, the warning persisted. The air valve sensors were sending incorrect readings due to depleted sensor batteries. The repair process included: Complete diagnostic scan, Testing each TPMS sensor, Replacing one faulty sensor with depleted battery, System recalibration Total cost was 280 Euro at my regular workshop, including parts and labor. The fix was permanent and the warning hasnt returned since. For more specific guidance on your case, could you share: Current mileage, Whether the warning appears on specific tires, If the warning becomes more frequent during temperature changes, Results from your last tire check with actual pressure readings These details would help determine if your issue matches what I experienced or if other factors might be involved.
