Volvo All Engines (2013 Emissions) Fault Code: P06B200 PID: ACM Sensor Power Supply “A” Circuit High

Volvo All Engines (2013 Emissions) Fault Code: P06B200 PID: ACM Sensor Power Supply “A” Circuit High

The control module provides the following sensors with 5V supply voltage
B115: Aftertreatment DPF Differential Pressure Sensor
If an abnormal voltage or current is detected on the common supply a DTC is set

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A137:50 is more than 5.5?V

Probable cause
1) Wiring harness
2) Connector
3) Aftertreatment Control Module (ACM)
