Volvo All Engines (2017 Emissions) Fault Code: P041A11 PID: EMS Exhaust Gas Recirculation Temperature Sensor “B” Circuit
Volvo All Engines (2017 Emissions) Fault Code: P041A11 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)
Actuator voltage is less than 8 volts for 13 continuous seconds
Observable symptoms
Loss of power
Probable cause
1) Wires between EGR Valve and Engine Control Module (ECM)
2) Connector
3) EGR Valve
