what is the procedure to reset the sensors after erasing codes.

usually "reset ride" usually consists of a 10-15 minute highway ride set at about 55 mph (which will get you ran over by the white haired old lady in the Buick with the big sunglasses over top of her regular bifocals) followed by a 2 mile stretch of forced stop and go driving (the exit I get off at is an industrial park with a long strait, easy visibility, 2 lanes both ways and, very minimal traffic) for hard acceleration up to 35-45 mph to a quickish stop, repeating the length of the road and turning around and doing it again to go back, stop and going the whole way back to the highway where the cruise is set at 55ish again for the ride home to see how many times I can be waved at minus a few fingers. Fortunately in PA we don't require all the monitors to be ready to pass, 1996-2000 are allowed to have 2 incomplete test while 2001-presently are allowed 1 (now that's incomplete, not failed)
