Volvo All Engines (2017 Emissions) Fault Code: P030600 PID: EMS Cylinder 6 Misfire Detected Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a common supply voltage to injectors 4,5,6 (Bank 2) and there are individual output transistor drivers inside the ECM to control each individual injector’s ground circuits. There are two solenoid circuits within the injector; a Needle Control Valve and a Spill Valve. Although they are separate circuits, the same fault code is used to identify a fault in the Needle Control Valve circuit and/or the Spill Valve circuit. Conditions for diagnostic trouble...

Volvo All Engines (2017 Emissions) Fault Code: P03351F PID: EMS Crankshaft Position Sensor “A” The Crank Speed Sensor is an inductive sensor that will generate a variable voltage signal when the sensor’s magnetic field is excited. When the engine is running the flywheel’s teeth rotate past the sensor’s tip and voltage pulses are generated. The Engine Control Module (ECM) monitors the frequency of the signal generated by the Crank Speed Sensor and calculates the engine RPM. Conditions for diagnostic trouble code (DTC):1) Incorrect crankshaft position (CKP) sensor signal Observable symptoms1) Long start time2) Uneven operation3) Loss of power Probable cause1)...
