Hello all! New to the forums!

And of course I have a issue that I come to you for help.. I have a 08 Colorado. And I just replaced all 4 tpm sensors because 1 was dying and I got a good deal on a set. They installed just fine. And the relearn process seemed to go just fine. But the light will not go off. Ive done the process around 4 times now. Ive seen in some other posts that the manual will say that if a "low tire" warning shows up during ignition that a sensor was bad, but I only have that show up when I put the truck in service mode when I try the relearn. Does that mean that one of the sensors is actually defective?

 

when the engine is running; is the tpm warning light flashing or just illuminated?


do any of the sensors display a psi value or just ---?


what process did you do to register the new sensors to the rcdlr?
