Volvo All Engines (2013 Emissions) Fault Code: P041A12 PID: EMS Exhaust Gas Recirculation Temperature Sensor "B" Circuit

Circuit description
The EGR Valve operation is controlled by the Engine Control Module (ECM) using a pulse width modulated signal.? The ECU provides both the power and ground circuits. The EGR Valve assembly consists of a solenoid, operating a valve by hydraulic pressure provided by the engine?s oiling system.

Conditions for diagnostic trouble code (DTC)
Supply voltage greater than 35V volts for more than 5 seconds

Observable symptoms
Loss of power

Probable cause
1) Connector
2) Wiring harness
3) EGR Valve
