Volvo All Engines (2017 Emissions) Fault Code: P052612 PID: EMS Fan Speed Sensor Circuit Circuit descriptionThe auxiliary fan provides extra engine cooling based on requests from the engine control module (ECM) Conditions for diagnostic trouble code (DTC)Engine runningThe voltage at pin A14.EA:35 is more than 65 % battery voltage Observable symptomsFan noiseThe fan will either be fully engaged or fully disengaged. Engaging and disengaging will however take some time.High fuel consumptionEngine cooling fan, does not reach expected speed Probable cause1) Fan speed sensor2) Wiring harness3) Connector4) Engine control module (ECM) Volvo All Engines (2017 Emissions) Fault Code: P052200 PID: EMS Engine...

Volvo All Engines (2017 Emissions) Fault Code: P053E00 PID: EMS Crankcase Pressure Too High The Crankcase Pressure Sensor is used to detect crankcase pressure system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Crankcase 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 engine control module (ECM) will set a diagnostic trouble code (DTC) if the sensor signal is not within predetermined limits. The ECM can also disable the engine brake, derate or shut down the engine to avoid engine damage.The...

Volvo All Engines (2017 Emissions) Fault Code: P054011 PID: EMS Intake Air Heater “A” Control The preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function. Conditions for diagnostic trouble code (DTC):1) Preheating requested2) The voltage at pin A14.EB:7 is less than 91 % of the battery voltage Observable symptoms1) Intake air heater (IAH) does not function2) White smoke at cold start3) Difficult to start in extreme cold Probable...
