ran over a parking lot concrete island, now have rear TPMS problems
So long story short I rounded a corner and discovered it wasn't where I wanted to go, did a 3 point-ish turn and didn't see a concrete island in the parking lot and up and over I went.
Scraped the frame/fiberglass in the front left behind the front tire and the rear right just in front of the rear right tire. There does not appear to be any other damage. Now I'm getting a SERVICE TPMS message and both of the rear sensors are showing XX PSI. Where is the signal for the TPMS picked up? Might I have snagged a wire somewhere? Where does the TPMS wiring run along the frame towards the rear of the car? I don't really see any wires vulnerable to getting snagged from scraping the bottom of the car. This is a 2007 C6. |

There are no wires. The TPMS uses a small round battery in each sensor which has about a 6 year or so life span. Some say they get more years - but 6 or so is an average. I would try to re-set the sensors first and if that doesn't work - well it's time to either replace the sensor or replace the battery in each sensor. The batteries are cheap but replacing the battery is a drawn out process which isn't hard but breaking the bead of the tire at home might be. I always have some old spare sensors ready for use which I have installed fresh batteries. I always take my car to Discount Tire for the re-learn which they do for free. In any case - it might just be a coincidence that your TPMS problem showed up when you ran over the concrete island. Good luck.

Discount tire rebuilds TPMS sensors for something like $7 each IIRC
|
"Rebuild" is a misnomer. They change the tire sealing "O" ring and add a new nut. The unit is not "rebuildable".
|
Where is the sensor that picks up the signals given off by each tire pressure sensor? Is that located in the rear of the car somewhere?
|
I dont know for sure but the receiver is probably behind the dash somewhere.
|
You may have bent a wheel also. Check out the wheels on a balancing machine when you replace the sensors at a tire shop.

All good info so far. Couple things you can try!
1. Deflate the tire let it sit 5 minutes then air it back up to what the placard says! That should reset the TPMS. 2. Have the tire shop scan the sensor to see if its still transmitting. If not then your sensor is bad. you need to replace. |

His car is a 2007, my understanding is that the deflate/inflate reset only worked on one year (2010?) if you have the stock sensors.
