TPS light on!

ChrisSlicks · 10-30-2009, 01:12 PM

Yeah, mine is on right now. Had auto-x on the weekend and was bleeding air out as the tire temps came up to maintain 34-35 psi. Now the temperature dropped so did the tire pressure and the light comes on. Just top them off to around 35 and drive a mile, the light should go out. I think the threshold is around 30 psi. If the pressures are correct and the light is still on then you could have a bad sensor. Just make sure you can keep them above 30 in the coldest weather and you should be ok.

Thanks for the info, guys. I assumed it was something like that because it had not gotten that cold 'til now. Unseasonable, record breaking cold in my part ot AZ this week. The first time I checked the air in the tires it was at 45psi! I took them all down to 36, but with the cold they all fell to 33-34 which is understandable. Now that the cold weather has subsided I will put them all at 36 and go for a drive. I'm sure that the light will go off.

I appreciate the answers! It's what makes this forum great.
