P0219

The ECM has the ability to set a DTC if engine speed exceeds a certain threshold. This threshold exceeds the fuel cutoff in both Park and Drive that the ECM already provides. This DTC may be set if the transmission is placed in a low gear while driving down a steep grade. Under normal conditions, engine speed should never reach this calibrated threshold.

DTC PARAMETERS
DTC P0219 will set if engine speed exceeds 7200 rpm when:
^ Condition exists for longer than 1 second
^ Engine is running

DTC P0219 diagnostic runs continuously once the above conditions have been met.

P0219 is a type D DTC

DIAGNOSTIC AIDS

IMPORTANT: This DTC does NOT infer a problem with the crankshaft position sensor or ECM.

This DTC indicates that the ECM had detected engine speed greater than the fuel cutoff limit in Drive. This DTC is most likely caused by the driver placing the transmission in a low gear while driving down a steep grade. Since this DTC does not turn On any telltales, verify and attempt to duplicate the customer concern if one exists.

Clear this DTC out of ECM memory.
