Volvo All Engines (2017 Emissions) Fault Code: P021900 PID: EMS Engine Overspeed Condition

Volvo All Engines (2017 Emissions) Fault Code: P021900 PID: EMS Engine Overspeed Condition

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) Engine speed too high

Observable symptoms
1) Unit Injector, Cut-Out

Probable cause
1) Wrong gear may be engaged (when engine braking)
2) Oil leakage
