Alrighty, I need to throw this one out to see if anyone can help me.

For some reason a light came on for the "Service Tire Monitor System". It looks like the monitors are not responding because 3 of 4 do not have pressures displayed when I go through to that menu. The warranty is up on my truck and I don't feel like spending 100 bucks or more to bring it in to have them diagnose the problem. Can I just try and relearn the tires as per the manual or can I somehow take care of this myself? Don't even know why these sensors are on there to begin with because it's just something else to go wrong and spend useless money on to fix instead of doing a new mod on the sled.

Thanks for any help.

If you don't care about checking the air preesure on the screen, you can replace them with standard valve stems. I did that on my wifes van because they all were bad and didn't want to waste the money on replacing them.

I think these sorts of things are going to be required on all vehicles very soon. The government determined they would save X gallons per year, so they are worth it. The govt of course didn't consider reliability of these systems. Too bad we can't just legislate that people use common sense and check their tires once in a while. Sorry this rant doesn't help you with your issue...

Just relearn the sensors yourself. Takes just a few min and the problem should go away. After an oil change and tire rotation at the dealership I had the same problem, called them and they said there was a problem with their gun they use to "teach" the TPS sensors. I did the relearn at home and no prob since.

The battery in the sensor must be failing. Each sensor in each wheel has a battery.

TPS system are federally mandated safety feature in all new vehicles, blame ford, firestone and the owners of explorers that never checked tire pressures. That is what started the federal laws that mandate these systems.

If your state requires yearly safety inspections your vehicle will fail if they don't work or are disabled. Its like removing the air bag. Not only that, if you are involved in an accident and its discovered safety features have been disabled, you may have problems with your insurance.

AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.

ACTION: Notice of proposed rulemaking.

SUMMARY: This notice of proposed rulemaking (NPRM) proposes to establish a new Federal motor vehicle safety standard mandating tire pressure monitoring systems capable of detecting when a tire is significantly under-inflated. A prior version of the standard, adopted by the agency in June 2002 in response to a mandate in the Transportation Recall Enhancement, Accountability and Documentation Act, was vacated by a decision issued by the U.S. Court of Appeals for the Second Circuit in August 2003. This NPRM, which is consistent with the Court's decision, proposes to require installation in new light vehicles of a tire pressure monitoring system capable of four-tire, 25-percent under-inflation detection. This proposed rule differs from the final rule also in that it tentatively responds to issues raised in petitions for reconsideration of the June 2002 final rule and proposes to require a TPMS malfunction indicator.

To get back to the original issue, How do you reprogram these things?

On my truck (2007 silverado) I set it to sensor learn mode with the button on the dash then it tells you what tire to start with you then let air out slowly till the horn honks then repeat on remaining tires in the order the manual tells you. When your done it honks twice.

Take it to any dealer or tire shop and they should reprogram them n/c. They are a pita and may or may not be able to reprogram yours. If they wont reset then you can buy an a/m sensor for about $40 or one from GM for about twice that plus labor to instal them. I work at a ford dealer and we dont charge to reset them. You must trigger the vehicle to learn mode then take a remote control size programming tool and hold it at each wheel sensor to get them all on the same page and synced to the vehicle.
Good luck!

Get the monitors reset,then spend the extra cash for a nitrogen fill on all four tires. Problem solved. Then if the monitor trips,you probably have a genuine tire pressure issue.
