Volvo All Engines (2013 Emissions) Fault Code: P253913 PID: EMS Low Pressure Fuel System Sensor Circuit

Volvo All Engines (2013 Emissions) Fault Code: P253913 PID: EMS Low Pressure Fuel System Sensor Circuit

The Fuel Pressure Sensor is used to detect low fuel pressure system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Fuel 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) if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EB:16 is less than 0.2?V

Diagnostic monitor condition
1) Key in ON position

Probable cause
1) Open circuit, Signal wire
2) Open circuit, Supply wire
3) Engine wiring harness
4) Engine Fuel Pressure Sensor
