Post subject:  Tire Pressure Monitoring System
Hi:
Today on the way home the amber tire pressure monitoring light in the dash went on. Also in the overhead counsel the display read "Check TPM System" for a few minutes. I went to the tire pressure screen and noticed there was no reading for the right front tire. The tire is not flat - so what do you think is the problem?

I'm hoping it's the tire sensor. The reason I think it the sensor is that the other tires show up on the display with pressure readings.

What do you think - is it the wheel sensor?
How much will it cost to have it repaired (unless it's simple to repair myself)?

Thanks;
Ken

If it is still there after starting and stopping the Jeep I would rotate the tires and see what happens. If it follows the tire its a good guess to say the sensor may be bad. If it doesnt follow the tire you may have other issues.

It is most likely a dead sensor

For what ever reason it's working again. The KJ sat for a few hours and now we're back to normal. Should it return I'll need to do the "will the fault follow the tire" game.

Thanks;

Whenever it happens again, don't change a sensor right away. These things are very sensitive, and they usually start working again on their own within a day or two. If you live where the temperature drops below freezing, there is a good chance that the problem is temperature related. I have experienced it a few times myself, and it always corrects itself eventually.

Post subject:  CHECK YOUR TIRE PRESSURE!
You said "the tire is not flat" but you didn't say you checked the pressure and found it to be... :shock: As another said it could be temperature related. Lower temperature, lower pressure. I had a sensor brake and it was like $20 mail order from that online mopar parts place.
