I took my '98 GS300 into an independent Lexus mechanic today after an amber "check engine" light came on. After diagnosing the problem, he discovered that my car has an "intermittent open circuit in accelerator pedal position sensor". The diagnostic code is: P1127: ETCS Actuation Power Source Circuit Malfunction. I have had no problems with acceleration (even with the light on). The mechanic did mention the car was operating fine for the moment. He then cleared the "check engine" light.
Question: Since this part is fairly costly and I plan on trading in the vehicle in about 6 months, is this something I can just continue to drive and see if it was an anomaly or is this something that can leave me stranded on the side of the road??
thanks,
