Yesterday I got into my car after work and had a "TPM Malfunction" light. I suspect it might have something to do with the weather as the temperature dropped from low 70's the day before to low 30's (although I didn't have a malfunction light in the morning on my way to work). Also it's not a low pressure warning, but rather a not functional error, so I'm not sure. I tried resetting but it it sat there for at least 5 mins attempting to reset but nothing ever happened. I was hoping it was something that would go away on it's own but no such lick, this morning on my way into work I had the same error (also it got colder and snowed over night....stupid snow).

Do I need new sensors, or is there something else that could be causing this?

Edit:
It's a 2007 that I've owned for just over a week now.

So my car had the same problem a few weeks ago. I went to tire rack and they checked all my wheel sensors and said they were fine. So I ran the codes with the bt tool and found out that the rdc transmitter (which sits inside each wheel liner and transmits to a central module located In the trunk) was malfunctioning, which throws the entire system off. Went to the dealer and got a $600 estimate. The part online is $70 and will take 10 minutes. Just jack up the car, unscrew the screws holding the wheel liner in place and pop in the new transmitter. I can send pics if this ends up being th problem. If you don't have a bt tool, Midas used to check my codes for free. Hope this helps

Well today is again cold and the Tpm malfunction light is now coming and going intermittently.

Oh will the tire rack inspect the sensors? I live in south bend so they are just a 10 drive for me. I'll make an appointment with them.

Will a generic obd cable read the code? I have that but nothing specific like a Bavarian technical cable.

Yeah tire rack will check them for free with a tool they have. Unfortunately a generic obd won't work. If you go to Midas, they'll read it for free
