Jimny TPMS Sensor Issues, Common Fix Guide

Had a similar TPMS issue on my 2019 Vitara last winter. Got the same low tire pressure warnings despite proper tire inflation. As someone with moderate car repair experience, I initially tried the basic resets and recalibration, but the warning kept returning. The root cause turned out to be depleted sensor batteries. TPMS sensors have internal batteries that typically last 5-8 years, and when they start failing, they often send incorrect readings or no signal at all. Had all sensors checked at my regular workshop, confirmed the battery issue. The fix required new TPMS sensors, cost me 280€ total including programming. Much better than constantly wondering if I actually had a flat tire or not. The repair took about an hour. Before suggesting specific fixes for your Jimny, could you share: Have you noticed if its specific to one tire or all of them? When did the warnings first start? Have you had any recent tire work done? Does the warning appear more during cold weather? These details would help determine if youre facing the same sensor battery problem or if its something else in the TPMS system.

Thanks for the detailed response. Just had my 156191 KM service last month, and this TPMS issue started right after. To answer your questions, the sensor fault appears on all tires, making me think its a system-wide problem rather than a single faulty sensor. The warnings are consistent regardless of temperature. The tire pressure readings seem completely unusual despite maintaining correct tire inflation. No recent tire work besides routine pressure checks during the service. Will probably need those new sensors like you mentioned, though hoping for a less expensive fix. 280€ for all sensors seems reasonable if it solves these constant false alerts. Think I should try a full system reset before heading to the workshop?

Thanks for those details about the timing of the TPMS issue starting after your service. The symptoms definitely match my experience with failing sensors, especially with those unusual pressure readings you mentioned. A full system reset is worth trying, but given the timing right after your service, I suspect they might have triggered a sensor fault during the tire pressure checks. Sometimes rough handling of the sensors during service can cause issues, which is exactly what happened with my Vitara. Before spending on new sensors, request the workshop to: 1. Check if the sensors were properly relearned after the service 2. Verify the sensor signal strength 3. Test the TPMS control module If these checks show sensor problems, replacing them solved the constant tire pressure warnings in my case. Though 280€ seemed steep initially, the peace of mind was worth it versus constant false low tire alerts. One thing I noticed with my repair, make sure they use OEM-compatible sensors. Cheaper aftermarket ones can cause intermittent TPMS issues down the road.

Thanks for all that info. Given how it started right after the service, I will definitely take it back to them first to check those points you mentioned. Makes sense about the possible rough handling during service, hadnt considered that. Will try the system reset tonight using the manual procedure, but will book it in for those diagnostic checks next week if that doesnt help. The constant tire pressure warnings are getting really annoying, especially since I keep checking the inflation levels with my pressure gauge and they are fine. 280€ for new sensors really isnt too bad if it fixes this TPMS issue completely. Better than wondering every time if I actually have a flat tire. Will make sure to ask about OEM-compatible sensors too, good tip about avoiding the cheaper ones. Thanks again for sharing your experience. Makes me feel better knowing someone else dealt with and solved the same problem. Will update once I know more after the workshop visit.
