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.
The engine is operating.
There are 5 ESO cycles with an RPM drop.
• | The control module stores the DTC information into memory when the diagnostic runs and fails. |
• | The malfunction indicator lamp (MIL) will not illuminate. |
• | The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records. |
• | The driver information center, if equipped, may display a message. |
• | A current DTC Last Test Failed clears when the diagnostic runs and passes. |
• | A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic. |
• | Clear the DTC with a scan tool. |
This DTC will not set if an external fuel source is causing an overspeed condition. DTC P1216 will set along with DTC P0219.

Important: Before clearing the DTCs, use the scan tool Capture Info function in order to save the Freeze Frame/Failure Records for reference. The control modules data is deleted once the Clear Info function is used. Did you perform the Diagnostic System Check-Engine Controls? | Go to Step 2 | |
Important: The new injection pump must be timed. Refer to Fuel Injection Pump Timing Adjustment . Replace the fuel injection pump. Refer to Fuel Injection Pump Replacement . Did you complete the replacement? | Go to Step 3 | -- | |

Does the scan tool indicate the diagnostic passed? | Go to Step 4 | Go to Step 2 |
4 | Does the scan tool display any additional undiagnosed DTCs? | System OK |
