Pontiac Vibe Vehicle Speed Control Safety Report | Jan 17, 2011
Reported on Jan 17, 2011
| ENGINE WOULD NOT RETURN TO NORMAL IDLE SPEED WHILE DRIVING. WHEN PLACED IN PARK OR NEUTRAL, ENGINE WOULD IDLE AT APPROXIMATELY 4000 RPM. ENGINE SPEED IN GEAR WAS APPROXIMATELY 2000 RPM AT A FULL STOP. THE ACCELERATOR APPEARED TO FUNCTION NORMALLY OTHER THAN THE HIGH IDLE ISSUE. THE ACCELERATOR PEDAL WAS CHECKED FOR OBSTRUCTIONS, OR ANY OTHER ISSUES THAT WOULD HOLD IT IN A PARTIALLY DEPRESSED POSITION. NONE WERE FOUND, AND THE PEDAL WAS UNABLE TO BE RAISED MORE THAN IT'S RESTING POSITION. THE THROTTLE BODY WAS INSPECTED, AND APPEARED TO FUNCTION NORMALLY. WITH THE KEY IN THE OFF POSITION, THE THROTTLE PLATE COULD BE MANIPULATED THROUGH IT'S ENTIRE RANGE OF MOTION BY HAND. A GENERIC SCAN TOOL WAS ATTACHED WITH THE KEY IN THE ON POSITION, ENGINE NOT RUNNING. THE VEHICLE SHOWED NO STORED OR PENDING CODES. ABSOLUTE THROTTLE POSITION READ 20% WITHOUT THE ACCELERATOR DEPRESSED, AND WENT UP TO 80% UPON FULLY DEPRESSING THE ACCELERATOR. A THROTTLE LEARN WAS ATTEMPTED. (WITH THE KEY ON/ENGINE OFF, THE ACCELERATOR WAS FULLY DEPRESSED FOR 5S, THEN THE KEY TURNED OFF, THEN THE ACCELERATOR RELEASED.) THE THROTTLE LEARN DID NOT EFFECT THE BEHAVIOR. THE ACCELERATOR PEDAL POSITION SENSOR WAS INSPECTED FOR LOOSE WIRING; NONE WAS FOUND. THE THROTTLE POSITION SENSOR WAS LIGHTLY TAPPED APPROXIMATELY SIX TIMES TOWARD THE CENTERLINE OF THE VEHICLE WITH A FLASHLIGHT. UPON THIS ACTION, NORMAL THROTTLE RESPONSE RETURNED. THE SUSPECT ACCELERATOR POSITION SENSOR IS STILL INSTALLED ON THE VEHICLE. *TR | |
