SPN111 FMI3
Coolant Level Sensor 1 Circuit - Voltage Above Normal or Shorted to High Source
CODES:
Fault Code: 195
PID(P), SID(S): P111
SPN: 111
FMI: 3/3
Lamp: Amber
REASON: Coolant Level Sensor 1 Circuit - Voltage Above Normal or Shorted to High Source. High signal voltage detected at engine coolant level circuit.
EFFECT:
-Automotive: None on performance.
-Marine: None, no engine protection for circuit or sensor failure.
Circuit Description:
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.
Component Location:
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.
Shop Talk:
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.
