TPMS question
 

sorry if this has been posted did a search but didn't help....

found a small nail in my right rear tire tpws came on fixed the flat at a shop i trust... but the tpws light is still on after driving at least 15 miles at different speeds. any ideas on this. had a 97 vette that i had to replace the value stem
on. is the 370 the same way.

It should reset within a mile. Does it flash before going solid? Did they plug it or patch it?

Did you check the pressure after the repair? I think the light will be on with any pressure less than about 26psi. I agree with sonic370.....if the pressure is above 27psi and you have driven the light should reset within a few nmiles of driving. Worst case, you can take it to a dealer and have them reset it with the Consult.

Above 40psi will also trigger the TPMS light.

it never has flashed and they plugged it.
they torn down the tire of the rim is that standard
then balanced it. Which I thought was strange they
took off the other weights. Re balance and then mounted

That is the normal procedure. When the tire is dismounted for a patch then the weights and balancing has to be redone since the tire position can (and probably will) change on the rim.

It is possible that the TPMS sensor got damaged during dismounting/mounting. You'll have to get it checked out. You can also try dropping the tire pressure to 25psi, driving a couple of miles and then re-set to 35psi, drive another 2 miles and see if that resets it.

i think baer had a DIY on tpms reset procedure. check it out.

i stopped using TPMS a while ago as it gave me more errors than anything.. plus swapping wheels often so it's tiresome to get it reprogrammed. i ignore the light.

related hijack..... I just put on new rubber and while wheels were at PC I ran other rays that had no sensors..... do I need to go to dealer to clear? should it self clear eventually?

all tires set to 35 psi. Are all the sensors the same? Possible I goofed and mixed 09 sensors with 2011 sensors.

I like my sensors, I've had it tell me i picked up a nail etc and allowed me to repair before I put a lot of heat into a low pressure tire.

should clear when you have the wheels with registered TPMS installed.

Pls humble me and tell me what "registered" means? If sensors from another car (2011) were inadvertently used then I need to have a dealer "register" them to communicate with the system?

Thanks for your input, ur always chiming in if you have the insight.

yah, the car needs to learn the TPMS in your wheelset your dealer has the tools to do it, some tire shops can do it too.

the only down side is that the car can learn only one set of TPMS sensors at a time... so if you have a few sets of wheels, you will have to either re-register each time you use the other set or ignore the light.

so for me, i dont bother using TPMS as i rarely only have one set of wheels for my hobby car.

thanks, I own two sets but the extra set was just to keep me going through the PC project. sold the rubber this weekend and will sell extra Rays next one has a couple paint scratches i will fix first.

yah, just put your stock wheels back on and drive around a block or two. the light should go out. :)

Could be a slow leak or may just need to be reset by the dealer. I had a sensor that needed to be reset for no apparent reason a second time now it appears to be fine now.
