METER / GAUGE SYSTEM Engine Oil Level Sensor Circuit

DESCRIPTION

The combination meter assembly and engine oil level sensor are connected via direct line. The combination meter assembly determines the engine oil level based on the engine oil level sensor ON/OFF signal.

Tech Tips

As the engine oil level may be unstable when the engine is cold or running at high speeds, the combination meter assembly receives the coolant temperature signal and engine speed signal from the ECM via CAN communication in order to prevent the oil level warnings from being output erroneously.
