Volvo All Engines (2017 Emissions) Fault Code: P008F00 PID: EMS Engine Coolant Temperature / Fuel Temperature Correlation

Volvo All Engines (2017 Emissions) Fault Code: P008F00 PID: EMS Engine Coolant Temperature / Fuel Temperature Correlation

The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn the driver and derate the engine to avoid engine damage if the signal is not within programmed limits.

Conditions for diagnostic trouble code (DTC):
1) Extreme variation in sensor values

Probable cause
1) Faulty sensor
2) Wiring harness
