Volvo All Engines (2017 Emissions) Fault Code: P06B316 PID: EMS Sensor Power Supply “B”

Volvo All Engines (2017 Emissions) Fault Code: P06B316 PID: EMS Sensor Power Supply “B”

Circuit description
The control module provides the following sensors with 5V supply voltage
B51: Engine Fuel Pressure Sensor
Engine oil pressure (EOP) sensor
B54: Crankcase pressure sensor

Conditions for diagnostic trouble code (DTC)
The voltage at pin A14.EB:17 is less than 4.5 V

Observable symptoms
Incorrect sensor value
Low Power
The engine oil pressure (EOP) gauge shows 0 when the engine is running

Probable cause
1) Wiring harness
2) Connector
3) Sensor
