My Tire Pressure Monitor System light just came on. Checked the tires and all are at correct pressure. Assuming I had a senor go bad in one of the tires. Is there a way to figure out which sensor/tire is bad? I find lots of "Re-learn" meters for sale but nothing that says they can test each sensor... Any help? . Dave F J B | ||

Scan tool, if you don't have a display that shows each tire. | |||

I have a pretty good OBD scan tool but don't see anywhere on/in it to check the TPMS. I hook it up again and check closer. . Dave F J B | |||

dave if you dont have a scanner that can pick up the signal off the sensor directly turn the key to the on position and hold the lock and unlock button on your factory remote key till the horn chirps...then starting with drivers front add or subtract air untill the horn chirps..then go rf...rr then left rear.. if any dont chirp after adding or subtracting air,,which could be as much as 30 seconds...could be the faulty sensor | |||

TPMS sensors have a battery in them... yours are 12 years old and the other 3 may not be too far behind. It may make sense labor wise to change them all out. Billy Duhs - BD104X@gmail.com | |||

If it doesn't have a display for pressure on the dash I guess you'll have to try reprogramming. My 2008 has the procedure in the owners manual so you can reprogram after tire rotation. If you know a good shop they might have the tool that can read each sensor. As someone stated the sensors have a battery in them and like everything they have a life. If one went out you'll now begin the process of replacing them either one at a time or all at once. | |||

OMG......Worked perfectly to find the bad one. THANKS jenavet !! Billy, I agree. I replaced the one bad one for now (without removing the tire from the truck lol) But ordered a set of 4 to to replace them all. . Dave F J B | |||

Go ahead and replace them all. They are cheap at Rock Auto. I replaced them by just breaking the outside bead. The relearn is easy. Youtube. Matt Ward | |||

Don't forget to check your spare. LOL, i put up with a light on my wifes lexus for months just blowing it off as a bad sensor and telling her to ignore it. When I changed the oil I checked air in the spare and it was down to like 20 psi. Whoops Mike Greene  | |||

Good idea. The truck does have the original spare tire. I should have ordered 5 sensors lol. . Dave F J B | |||

For those that want to cut to the chase, here's albeit a limited coverage option (not Dave's), from an outfit in the UK. https://tpmsbypass.com/ Illegitimi non carborundum | |||

If you're going to pay money anyway, why not spend it on fixing the issue(s) and keep the low pressure sensor system in place? Hell, I was thinking of putting one on the trailer. Had trailer tires do a shytload of damage before. . Dave F J B | |||

Just an option for those that want to end the big brother mandates once and for all. One can check air pressure just like you've always done. Those that like it can certainly replace batteries/sensors from time to time. Illegitimi non carborundum | |||

What's wrong with just taking the lightbulb in the dash out?  . Dave F J B | |||

The GM vehicles I've dealt with don't use a sensor for the spare, only senses the 4 on the ground. The system sucks for a lot of reasons especially the $100 plus for sensors if you keep your vehicles. The false alarms when it gets cold out and pressure drops can be like the boy that cried wolf. I've known people that get used to the light coming on when it's cold and they don't stop and look so they end up ruining a tire. | |||
