TPMS Issue

samedi 26 septembre 2020

So, I bought new tpms sensors for my 99 when I bought wheels. The car is reading my tire pressure for all 4 tires as 5-6 psi lower than what they actually are according to a handheld gauge.

I’ve tried re-pairing sensors with the car, and I’ve tried airing them up to ~44 psi and driving around to see if they’ll adjust.

Something I read mentioned the 97-00 sensors/pcm had some kind of correction for altitude. Is that true? If so is there some kind of pcm change I could make to fix it?

If the sensors are just bad, then i’d rather not replace them. Is there some way to get the car to un-recognize the sensors so that I don’t have to deal with the low pressure warnings?
