ok theres the deal for whatever reason my tire pressure sensor is reading my Right Rear Tire pressure at 25 PSI even though I have it air to 35. I have checked it 3 times in the past 3 days and its remained the same and the caution light on the Console and the HUD wont go away...lol any ideas on what the heck is going on? 2007 Pontiac Grand Prix 3.8L v6 stock except a few minor things. any ideas would be greatly appreciated
