Tire Pressure Light Won't Turn Off

[SunlitComet]

it read higher or lower and will light up for either. every 30 second of tire spin will cause a transmitting of pressures and dic will respond accordingly. here is some info to help and a tsb that may apply to you.

I agree with "lx4life", have you attempted the "relearn" process?

Tried it, no luck. I think I'm gonna unhook the battery and see if that clears it.

Ask your dealer?

Seems like maybe a bad sensor needs replacing?

I was thinking that's possible, but I don't think that's what it is. The sensor will still tell me the tire pressures correctly so it seems weird that suddenly it thinks pressures all the way up to 40psi are too low. The users manual says that if there's a problem with TPMS, the light will flash on the dash for a minute when you start the truck, and then will stay lit. Mine doesn't flash.

Yeah. I've had the truck for about a month and a half, but due to two big roadtrips I've already put 3,000 miles on it so it's gonna be ready for an oil change soon. I was thinking I'd take it to a dealership to have that done and they can look at the TPMS light at the same time.

I finally got around to unhooking the battery and hooking it back up. Looks like that cleared it. I'll keep an eye on it though.
