Hello, I just bought a 2004 G and I have a question. My car recently showeda exclamation point on the dash. I thought it may be a check engline light so, I took it to auto zone and let them run a diagnostic check and it came up with no codes. It comes on and off often and im not sure what it means. Anyone know what this means? Thanks.

 

TPMS, Tire pressure sensor light.
It just means your sensors aren't talking to your car, or you don't have sensors, or they need to be re-programmed.

 

Ok thanks... How do I correct this problem?

 

First check your wheel to see if you have these types of stems




If you don't then you don't have TPMS in your wheels. If you do, then check your tire pressure. Make sure you have at least 30psi in all of your wheels. If you do, then you have a problem. Many situations can cause the system to act up and only the dealer can really find out why (as far as I know). Honestly, the hassle isn't worth it. I have always checked my own tire pressure every other fill up.
