During normal driving activities, the accelerator pedal will stop functioning. At this time, the check engine light illuminates and the engine idle is held steady at approximately 1500rpm. The car cannot accelerate with the accelerator pedal. Shutting the car off for 60 seconds or more is required. Attempting to start before the 60 second time results in the engine not starting. After the 60 seconds, the engine starts and appears to operate normally except with the cel illuminated. The associated code from the ecm is p2138.
