Volvo All Engines (2010 Emissions) Fault Code: SPN 94 FMI 1 PID: Engine Fuel Delivery Pressure
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) Fuel pressure critically low
Observable symptoms
1) Fuel injection can be affected
2) Low Power
3) Leakage
Probable cause
1) High differential pressure across the filter
2) Engine Fuel Pressure Sensor
3) Wiring harness
4) Leakage
