Service Tire Monitor System

ronanberry · 08-10-2010, 09:52 AM

I keep getting "Service Tire Monitor System" every time I start the car. I'd like to try to fix this myself if possible.

Any Ideas?

Thanks

Based on my experience, you probably have a wheel sensor going bad -if you have one tire showing no pressure, that should be the one that needs to be replaced.
I had one that would work sometimes, but eventually had to have it replaced.
It may be possible to do it yourself, but you will have to get the tire off the bead of the rim on the outside lip enought to replace the valve stem/ sensor assembly.
The cost to have the dealer do it this past January was $75.00 for the part and $50.00 labor.

I agree. Look at what the tires are reading. Increase the pressure a few PSI then drop them back to normal. This might show which one is bad. Of course since it involves removing the tire from the wheel it is not a good DIY job.

ther is a service bulletin on this matter. the dealer has to reflash the computer to make it less sensitive

Honestly I wouldnt even bother... I have had my TPMSensors replaced multiple times by the dealer... they are simply terrible. After about 5 months they start failing again. I have come to just ignore it. Its something I decided I could live without.

I guarentee if you spend the money to buy a new sensor it will just end up going bad again a few months down the road.

When the dealer did the reflash thing my senser would work for a while, but would crap out periodically. But, the one they replaced has been working great for about 6 months -we'll have to see if it keeps working.

Maybe the dealer just "re-flashed" mine as a quick fix... it seems that whenever I am driving, all of a sudden I will get the Service TPMS warning because one or two tires will not be picking up a reading. Usually the light goes away after I turn off the car and re-start.

These little sensors are awfully expensive for very little value added!

I agree, I wish there was a way to turn them off!
