Tire Sensors
I contacted GM technical assistance today and they will not or can not issue a VCI re-program number for tire pressure sensors on 2007 and older HHR's. I asked them if this would be coming in the future and they could not answer with a yes or no. Simply putting the sensors in the wheels will not turn them on to work. The module that controls the door locks and remote start has to know to find the signals to then give to the BCM for displaying. I told the GM tech that this is something a lot of owners were interested in, so if she would pass that on to the "powers to be" I would appreciate it.

Even if this can't be done with factory parts, there is always the aftermarket. www.tirerack.com has them.
By 2008 all new cars sold in the US market have to have T.P.M.S (Tire pressure monitoring system) However, you can purchase an aftermarket retrofit kit and have it installed either using your current cig lighter/ accessory outlet or by hard wiring it directly in the fuse panel.
