low tire pressure warning

[Wheats]

Lastnight and this morning the low tire pressure warning light came on and after stopping, all the pressures were normal. Is anyone else having this problem? I have 2500 miles on the truck and this is the first time this has happened.

Brian, This happened to me a while ago. I pumped all tires up to 40 lbs, and left it overnight. I let them all down to 35 lbs in the morning, and the light didn't come on after that. I think that it is a sender problem in one of the wheels. They aren't supposed to set of the alarm unless the tire pressure goes below 28 psi. Mine were all at 35 when it occured. I think that it I could probably let them down one at a time to about 30-32 psi, and find the one that is not accurate.

Describe the time/length of drivetime prior to the low pressure light coming on.

Austin, I think that you are probably asking Wheats this question, but in may case, it came on within a mile of leaving for work one morning. The manual says that the sensors start working when you reach 20 mph. Right after I filled mine to 40 psi, I drove it just a couple of blocks in my neighborhood, (probably didn't reach 20 mph) and it didn't reset, so I parked it. The next morning after I let the pressure down, and started the truck for the first time that day, the warning light stayed off.
