so the 05-06 tCs do not have an actual sensor in each wheel, but calculate wheel speed off of the ABS sensor. This is a pointless system since it doesn't actually measure the tire pressure.

I recently had to get 2 new passenger side tires because of potholes and the front left tire now has less tread than right one. I believe this is setting the light off because of the slight change in rotation. Before anyone chimes in about what my tire pressure is, I have it set at 35 PSI in the front and 32 PSI in the rear (on the door it says 32/front and 29/rear, a 3 PSI difference. Since I added a little more air in each but kept it at the 3 PSI difference it shouldn't matter since in theory all the wheels should read equal. When I had all new tires this worked fine) and this has been a problem since I bought the car (used) last year. The only way the light stayed off is when I bought all new tires, or replaced them in pairs. Buying tires is getting expensive...

I can't take the damn light on my dash anymore. it's frustrating when I know nothing is wrong. is there a way to reset it to what i'm running now regardless of tire pressure/wheel circumfrence? I'm sure there isn't a way to turn the system off but maybe change the settings? I'm about to take the friggin' LED bulb out as a last resort...


**EDIT** I did a search and found there was no way to deactivate it, so if anyone has some helpful info on getting it set properly then that'd be great.

I prefer not to have TPMS but anyways there is a way to reset it. Look in your owners manual.

I believe there is also another way to disable the system as well.

you need to reinitialize the system.. hold button until it the light blinks 3 times..

it's in your owner's manual..

page 110 to be exact... and you can read pages 107-109 while you're at it too.
