Circuit Description
The ECM supplies a 5-volt supply to the engine coolant level sensor using a common sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The coolant level sensor 1 monitors the engine coolant level within the coolant system and passes information to the ECM through the OEM harness and engine harness.
Component Location
The coolant level sensor 1 is typically located in the radiator top tank or surge tank. Refer to the OEM troubleshooting and repair manual for location.
Shop Talk
Some engines are equipped with a 2-wire sensor instead of a 3-wire sensor. The 2-wire sensors do not have the 5-volt supply wire in the circuit. Possible causes of this fault code include:
Signal circuit shorted to ground or return in the harness, sensor or connectors
An open supply circuit.
