: Service Tire Monitor System.. Just turned on

05-25-12, 11:35 AM
I was driving to work its 85 degrees out and all the sudden my Dash tells me "Service tire monitor system" so i check the tire pressures thinking maybe one ios down and the left rear tire is showing --.

Anyone know what can cause this the tires are all fine i even manually checked the pressure.

tpms sensor went bad or stopped communicating with the system.

Some times the batteries go, they only last usually 4-6 years, and some times they just get confused

Hello PeteKT,

It looks as though you're well within the Bumper to Bumper warranty by mileage; we can check with the last 8 digits of your vehicle's VIN to see if you're still within the mileage by date (4 years from the in-service date of the vehicle). Generally speaking, the Bumper to Bumper warranty covers against defects in materials or workmanship for most vehicle components (maintenance items excluded), but a dealership diagnosis helps us to determine if a vehicle concern was caused by an environmental factor, etc.

Again, we can check into the expiration date of your Bumper to Bumper warranty if you were to send us the last 8 of your VIN.

I would try and relearn the sensors per your owners manual and see if that corrects the problem. You pick relearn from the dic and go to each tire and let pressure out until the truck honks at you and then move on to the next tire and repeat. You start at the left front then rf, rr, lr and then It honks twice I think. Try this before you take it some where.
Once set, adjust the tire pressures and your golden. I hope.

My right wheel shows dashes .
Any ideas beside replacing the sensor?
Actually question can I replace only one sensor?

Do the re-learn procedure first, and if that doesn't work, order a set and get it replaced. Matter of time before the others start going bad, too. Be thankful this is a very easy repair! I've heard friends being charged $4-500 to get theirs replaced for their BMW.

We have been replacing a lot of 2007 and 2008 sensors as the batteries are starting to die. :(

it weird happened yesterday at night. So we were originally going on our daughter graduation ceremony from college, and we were driving along with same Esky ESV as ours for few minutes, side by side, than that
msg pop - "Service tire monitor system", so while were waiting to ceremony started I typed original msg. On way back, tire light was on, but right tire shows correct pressure. We came home and I decided to restart
the car, and light went away????!!!
So can be it the signal interference with other truck on my left? It's really weird.
But thanks to all for replays.

One of my sensors did the same thing for a couple of weeks before the battery finally died. I would get the dashes, then it would go away and show correct pressure reading. The relearn didn't help in this case. If it happens to you again, the battery in the sensor is going. You can replace one at a time but they are all probably on the way out.
