TPMS Light Won't Quit!

[Trendkill]

So I’ve got this annoying TPMS warning on my Fiat 500e that’s been bugging me for weeks! I’ve got my tires all pumped up, and I did the AlfaOBD scan - zero faults, folks. However, the tire pressure graphic on the RH stalk is totally blank for all 4 tires! Anyone else run into this? Got any clever workarounds? It’s driving me nuts with no tire shops or mechanics around!

Hey, buddy! You should definitely think about swapping those sensors out. No clue how old your wheels are or how many miles you’ve put on 'em, but those sensor batteries might be toast. Just pop into a tire shop - they've got all the tools to check if those sensors are acting up!

It sounds frustrating! Since you’ve already checked tire pressure and ran an AlfaOBD scan without finding any faults, it might be a sensor calibration issue.

Not sure if it’s got anything to do with the TPMS, but I left my car charging for like six months - totally had my reasons! Only to find out that the breaker tripped, leaving the HV battery at 0%. The 12V battery still lit up the goalposts, though! After a quick unplug and replug of the HV connector, I cleared the error codes, and it started charging again. Everything runs great, just that annoying TPMS warning

Wow, what a wild ride! Awesome that you got it running again. The TPMS can be a pain. Since you've checked the basics with AlfaOBD, maybe check those sensor TPMS connections, they can get loose or corroded if the car's been sitting for a while. Good luck!
