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
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
^ The PCM will turn the MIL off after three consecutive trips without a fault condition.
^ A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures
^ The use of a scan tool.

Diagnostic Aids
This DTC will not set if an external fuel source is causing an overspeed condition. A DTC P1216 will set along with DTC P0219.
