Fixed....then not working again.
Canadawrx - After all the trouble I've had, I would definitely go without the sensors. If you don't install sensors you'll just get one chime after start up, the TPMS warning lamp will flash several times and then it will stay lit up continuously for the duration of your drive. I'm sure I could easily ignore the warning light on this vehicle - It is small and dim. I've heard of some people putting a small piece of tape over it if it bothered them.
So my continuing saga with my vehicle goes as follows:
Took the van in to the dealer today. They reportedly had to use a reader to determine the part numbers of the new sensors on each new winter wheel. Then they had to program the new sensors into the WCM (Wireless Control Module). They reportedly "cleared the codes" then road-tested the vehicle & had no warning lights come on. They told me they would have to re-program the WCM when I put the original summer tires back on and that there was no way around that. Needless to say I was not happy about that. I want to be able to do my own wheel/tire changeovers without having to see the dealer.
So I drove the van home. While making the second to last corner, the friggin TPMS warning light came on again.
I checked the tire pressures (hot) and found they varied a bit between 38 and 41 psi. (I had just set them cold to 36 psi a couple days ago). Figured these pressure/ temperature variations may be normal after the drive.
I'll check the cold tire pressures again in the morning, but I expect they'll be very close to the specified 36 psi.
I think I'll be contacting the tire shop and kindly requesting they remove the sensors from the wheels and refunding the $. Don't know how successful that will be - Wish me luck. The tire shop and dealer will probably point fingers at each other.
I'd rather put up with the TPMS warning light for the winter months, and not have to see the dealer to re-program the system at each changeover. I've spent way too much time & energy on a simple winter tire installation as it is.
For some reason I had no problems at all with the TPMS on my 2006 Toyota Matrix when I installed steel wheels and winter tires, and they've functioned flawlessly for a couple changeovers now.
My opinion - These systems are a royal pain. They add little in the way of safety, primarily to those who neglect to properly maintain their vehicles.
