Coolant Level Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source
|Fault Code: 195
Coolant Level Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at engine coolant level circuit.
Automotive: None on performance.
Marine: None, no engine protection for circuit or sensor failure.
Engine Coolant Level Sensor Circuit
The engine coolant level sensor monitors the engine coolant level within the coolant system and passes information to the electronic control module (ECM) through the OEM harness.
The engine coolant level sensor is typically located in the radiator top tank or surge tank, for marine engines, it is located in the expansion tank. Refer to the OEM troubleshooting and repair manual for location.
Possible causes of this fault code include:
- Open return or signal circuit in the harness, connectors, or sensor
- Signal wire shorted to sensor supply or battery voltage.
