Volvo All Engines (2017 Emissions) Fault Code: P06B500 PID: EMS Sensor Power Supply B Circuit High

Volvo All Engines (2017 Emissions) Fault Code: P06B500 PID: EMS Sensor Power Supply B Circuit High

The control module provides the following sensors with 5V supply voltage
1) B51: Engine Fuel Pressure Sensor
2) B54: Crankcase pressure sensor
3) B118: Engine oil pressure (EOP) sensor
4) B207: Engine Piston Cooling Oil Pressure Sensor

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EB:17 is more than 5.5 V

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

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