DTC P0219 Without RPO CTF
Circuit Description
If the engine control module (ECM) detects an engine overrun condition the ECM shuts off fuel injection.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
The ECM detects an engine speed of 3,750 RPM or higher.
Action Taken When the DTC Sets
| • | The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails. |
| • | The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records. |
| • | The ECM stops fuel delivery. |
Conditions for Clearing the MIL/DTC
| • | The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. |
| • | 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 emission related diagnostic. |
| • | Clear the MIL and the DTC with a scan tool. |
Step | Action | Yes | No |

1 | Does the DTC set with the ignition ON or with the engine operating? | Go to Step 3 | Go to Step 2 |
2 | Ask the driver if overrun is caused by gear slip-out, shift error, etc. Did you complete the action? | Go to Step 3 | -- |
3 | Clear the DTCs and operate the vehicle. Do any other DTCs set? | System OK | |
DTC P0219 With RPO CTF
Circuit Description
If the engine control module (ECM) detects an engine overrun condition, this DTC will set.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
The ECM detects an engine speed of 3,750 RPM or higher.
Action Taken When the DTC Sets
| • | The ECM does not illuminate the malfunction indicator lamp (MIL) when the diagnostic runs and fails. |
| • | The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Failure Records. |
Conditions for Clearing the DTC
| • | A current DTC, Last Test Failed, clears when the diagnostic runs and passes. |
| • | Clear the malfunction indicator lamp (MIL) and the DTC with a scan tool. |
Diagnostic Aids
| • | This DTC is caused by an engine overspeed condition, which was most likely caused by driver error (i.e. downshifting a manual transmission on a steep grade). Since this DTC does not illuminate any lamps, clear the DTC and ensure there are no signs of engine damage. Excessive engine overspeed may damage internal engine components. |
| • | Make sure the CKP sensor is tight and the sensor wheel teeth are not damaged. |
Step | Action | Yes | No |
