I have an 04 and have an intermittent problem with one or more sensors. I'm pretty sure the batteries in the sensors are about done. The light will be on for two or three weeks and then off for a few days. Started on the first cold day last September. Had it in for service a couple weeks ago and asked them to check it. Unfortunately after three weeks of the light being on it was off the day of service and "No Problem Found". It was back on two days later. No problem with pressure, I check regularly since this started happening, always within 1/2 PSI.
