Volvo All Engines (2017 Emissions) Fault Code: P046C64 PID: EMS EGR Differential Pressure Sensor Circuit Range/Performance This Diagnostic Trouble Code (DTC) monitors and evaluates malfunctions in the (EGR) Exhaust Gas Recirculation Diff Pressure. A faulty (EGR) Exhaust Gas Recirculation differential Pressure can lead to uneven running and response problems. Conditions for diagnostic trouble code (DTC):1) Abnormal sensor signal Observable symptoms1) Possible engine de-rate2) Exhaust leakage Probable cause1) Connector2) Wiring harness3) Clogged ports4) EGR Cooler5) EGR system pipe and connections6) EGR differential pressure sensor Detailed information Activation1) The diagnostic trouble code (DTC) is first set after 30 min when driving with varying...

Volvo All Engines (2017 Emissions) Fault Code: P047012 PID: EMS Exhaust Pressure Sensor “A” Circuit descriptionThe purpose of the engine exhaust brake closed loop butterfly valve (butterfly valve) is to create a controlled exhaust back pressure upstream of the butterfly valve. The butterfly valve consists of the housing, shutter, shaft, bushings, pneumatic actuator, spring, and a bracket assembly. The shutter is kept in an open position by the spring when not activated. A pneumatic actuator closes the shutter when activated. The actuator is activated by the Engine Control Module (ECM). An exhaust pressure sensor located upstream from the shutter monitors...

Volvo All Engines (2017 Emissions) Fault Code: P047013 PID: EMS Exhaust Pressure Sensor “A” The Engine Coolant Temperature Sensor is a thermistor. The resistance of the Engine Coolant Temperature Sensor changes inversely to the temperature of the engine coolant. When the coolant is cold, the sensor resistance is high. As the temperature of the coolant increases, the sensor resistance decreases.The Engine Control Module (ECM) monitors the voltage drop across the Engine Coolant Temperature Sensor.The coolant temperature signal is used to calculate fuel injection and to evaluate operating conditions of the engine coolant temperature. Examples of conditions that may cause high...
