| Post subject: | Tire pressure light question |
Today while driving I had my tire pressure light start flashing. So I pulled over and checked all of my tires and they were fine. I shut it off and restarted it and its still on. It will alternate between flashing and solid. Any of y'all have any ideas? I'm thinking it could be one of the sensors out. |

Wait till tomorrow morning to check them while they are completely cold. Fill them up after that. The light still might be on for a few miles. When I had a nail in my tire removed, the light stayed on for a few miles and eventually went off. Might be the sensor though. EDIT: Do you have an EVIC to show which tire it is saying is low? |

The flashing means there is a system fault, nothing to do with air pressure. It will flash for 70sec then stay solid until the next key cycle. Mine does this every once in a while, then goes away. Supposedly radio interference can cause it. If it is staying around, it is probably a bad sensor (~$50) or a bad WCM (~$200). If you have a ELM327 or similar OBD reader, you can send a command and have it report the DTCs, otherwise, you are stuck going to someone with the dealer tool. |
