Volvo All Engines (2017 Emissions) Fault Code: P055A64 PID: EMS Engine Oil Pressure Sensor/Switch “B” Circuit descriptionThe Engine Piston Cooling Oil Pressure Sensor is used to detect engine piston lubrication and cooling system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Engine piston cooling 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...

Volvo All Engines (2017 Emissions) Fault Code: P055F00 PID: EMS Engine Oil Pressure Out of Range 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...

Volvo All Engines (2017 Emissions) Fault Code: P056000 PID: ACM System Voltage Circuit descriptionThe aftertreatment control module (ACM) uses the aftertreatment diesel exhaust fluid (DEF) dosing pressure sensor value to adjust and maintain DEF pressure at the DEF dosing valve by controlling DEF pump speed. If the pressure decreases below expected value when the pump is in initial pressure build-up mode or if the pressure increases above expected value when pump is in idle speed mode, the ACM considers DEF pressure outside of normal operating range and indicates a malfunction in a DEF dosing pressure sensor. Conditions for diagnostic trouble...
