Buick LeSabre



  • To get back to your original question if you havent figured it out by now...I have an 01 buick lesabre and i had the same problem. It turns out its easier then everyone is making it out to be for you. There is a sensor where the cap screws into. Clean the sensor and the area around the cap very well. It might take a few days for it to go off. If this doesnt work clean the fuel injector rail where the main line connects. Take off the rubber clip and clean well. If you really dont have a pressure leak this will do the trick!
