Had a flat repaired and my TPMS is "stuck" at 51psi. After first seeing the TPMS at 51, I let a good amount of air out of the tire, enough to release at least 8-10 psi. The TPMS still read 51psi. I went home and shut the car off for a while thinking it would reset. It didn't!

Looked in the manual how to fix/reset the TPMS - no help found.

What do I need to do? No problem going back to my mechanic but I'd rather fix it myself if I could.

 

jack it up so that said wheel is floating.. release the air and start the car.

wait a few mins and see if the PSI changes, if it stuck there then your TPMS is fucked up and you will need a new one.

 

What exactly did you do to get the flat repaired? Could be the shop that fixed your tired damaged your TPMS sensor.
Another option to try and diagnostically figure this out is to rotate the tire out of it's current position on your car and see if the "51" moves to a different location on your TPMS display.

 

moving it wont do anything, the problem is that it is readying the tpms wrong.. like i said.. deflate that shit, see if it reads low psi.

 

There is nothing to reset the TPMS sensor.

It either works or doesn't.

 

Theoretically if you move the "bad" wheel from its current position and put a good wheel in that position it will either read correctly or not. If it reads correctly you know the sensor that reads the TPMS is good and the TPMS sending unit in the wheel is bad. If it reads incorrectly, then the sensor is likely bad. From there you can check to see if the "bad" wheel reads correctly in a different position.

 

probably worth a "try"... but i wouldnt even bother trying... mechanic touched the TPMS and not the sensor.. rarely do those things go bad.. and when it goes bad, it usually just doesnt read.. it should not show 51 PSI... id bet money its on the TPMS itself since it was tampered with.

 

You are more than likely correct, but I always like to know as much as I can about the problem before heading to the mechanic. Less opportunity to get snowed.

 

Went back to the shop and completely deflated the tire. The sensor is now working as it should. Thanx for all the help.

 

Glad it worked out for you.
