Volvo All Engines (2017 Emissions) Fault Code: P008B97 PID: EMS Low Pressure Fuel System Pressure – Too High

Volvo All Engines (2017 Emissions) Fault Code: P008B97 PID: EMS Low Pressure Fuel System Pressure – Too High

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 delivery pressure too high

Observable symptoms
1) None

Probable cause
1) Wiring harness
2) Aftertreatment Fuel Pressure Sensor
3) Fuel filter
4) Fuel pump
