DTC P0219: Engine OVERSPEED: Description

WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

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.
