Hey guys,

I have a bit of a problem with my TPMS and I was wondering if you could help shed some light on the problem. The Tire pressure light came on one night while I was driving and I checked the tire pressure and everything checked out to be fine. The light then went away and I thought it just was a fluke. Then the tire pressure light came back on about a day ago, I have been driving around for a day and nothing has changed and the tires are at their normal pressure. What could be happening? Is there anyway i can reset this light?

Thanks,
Dan

 

Probably a faulty pressure sensor - it will have to be replaced.

I assume when you read the pressure on the display, one of them is below 28psi or showing "--", correct?

 

Does the 2006 model show the actual pressure in a display? I'm not sure, but thought that it was only a warning light for TPMS function in that year car.

According to the 06 Owners manual, the Trip Computer still displayed the individual PSI values. It was probably 07 when they took the display away and went with the warning only.

 

My 2004.5 model shows the actual pressure in the display + warning light, some are equipped with it and some are not. I love it.

 

DaveZ#3, correct. And thank you, that is probably what is wrong now that I think of it. Do you or anyone else know how much money this might run?

Thanks in Advance,
Dan

 

DaveZ#3 is always correct. He checks his facts before posting.

Something else to consider... I had the same problem you describe. My dealer reset my TPMS sensors, and that fixed it. So maybe you should try this first before replacing any sensors.

Are you looking at the on-screen tire pressure monitor, and checking it manually with a tire pressure gauge?

 

^^ Yes. That would be the only way to check it accurately.

In fact I periodically check my TPMS display against real tire pressures using a quality analog rotary tire pressure gauge. There are some good digital gauges as well, but the good ones are "pricey."

I think the DaveZ#3 is correct (you probably have a "bad" sensor), but thought I should mention recalibration since that was a fix for my problem and spared the cost of buying a new sensor. Even it it turns out being a bad sensor, you still are faced with the cost (albiet it is minor) of doing a recalibration when installing a new sensor.
