Diagnostic Test
1.ACTIVE DTC
NOTE: Maximum engine speed could be reduced while this fault is active, it just depends where the throttle
gets stuck.
Ignition on, engine not running.
NOTE: The PCM tests the ETC Motor by opening and closing the Throttle Plate before starting the engine.
If during this test the Throttle plate does not return to the closed positionthisDTCsets.
With a scan tool read DTCs.
NOTE: Diagnose any TP Sensor or 5-Volt Supply DTCs before continuing.
