DTC Parameters
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
DTC sets if the commanded throttle plate position (based on the actuator motor pulse width) differs greater than a calibrated amount from the actual throttle plate position (based on the TP sensors); or if a throttle actuator motor circuit fault occurs. Condition exists for longer than 0.5 second.
NOTE:
The MIL will only illuminate if the fault is present for longer than 5 seconds.
