Diagnostic Chart:

Schematic:

CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) has the ability to put the vehicle in an Engine Shut-off (ESO) solenoid controlled idle if an engine overspeed condition has been detected.

CONDITIONS FOR RUNNING THE DTC
The engine is operating.

CONDITIONS FOR SETTING THE DTC
There are 5 ESO cycles with an RPM drop.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM will not illuminate the Malfunction Indicator Lamp (MIL).
^ The PCM records the operating conditions at the time the diagnostic fails. This information is stored in the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A History DTC clears after 40 consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
^ Use a scan tool in order to clear the DTCs.

DIAGNOSTIC AIDS
This DTC will not set if an external fuel source is causing an overspeed condition. DTC P1216 will set along with DTC P0219.
