The engine normally responds to a failed open accelerator position sensor circuit fault by returning the engine to low idle speed of 800 RPM and disabling the driver's ability to increase the engine speed. However if the open circuit corrects itself within 30 seconds of initiation, engine speed could suddenly increase to a high idle speed of 1200 RPM.
