VOLVOUU All Engines (2013 Emissions) Fault Code: P240F00 PID: EMS EGR Slow Response

VOLVOUU All Engines (2013 Emissions) Fault Code: P240F00 PID: EMS EGR Slow Response

This function is used to calculate the EGR Mass Flow. The Engine Control Module (ECM) monitors the EGR diffpressure sensor and the EGR temperature sensor after cooler and uses these signals to calculate the EGR Mass Flow data.

Conditions for diagnostic trouble code (DTC):
1) EGR mass flow above calculated value
2) EGR mass flow is below calculated value

Observable symptoms
1) Exhaust smoke

Probable cause
1) EGR Valve
