Volvo All Engines (2013 Emissions) Fault Code: P06DD00 PID: EMS Engine Oil Pressure Control Circuit Performance/Stuck Off

The Engine Oil Pressure Sensor is used to detect engine lubrication system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Engine oil pressure causes the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.
The sensor’s signal is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the engine to avoid engine damage if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) Oil pressure regulation valve is not working

Observable symptoms
1) Engine de-rated
2) Low Power

Probable cause
1) Lubrication and Oil System
2) Piston Cooling Valve
3) Engine oil pressure (EOP) sensor
4) Oil Pump
