Volvo Engine D11L (Tier 4) Fault Code: P04009C PID: PPID 35 FMI: 1 Exhaust Gas Recirculation “A” Flow – Low/Insufficient Flow

Volvo Engine D11L (Tier 4) Fault Code: P04009C PID: PPID 35 FMI: 1 Exhaust Gas Recirculation “A” Flow – Low/Insufficient Flow

CONTROL UNIT:
Engine ECU

FAILURE EVENT:
Temperature difference too low in inlet manifold when activating EGR valve (<3?C / <5?F). SYMPTOM: 1. Low power because of engine derate. 2. Display message: SCR system failure, derate will occur soon. CONDITIONS: 1. Ambient air pressure between 75 kPa (10.9 psi) and 200 kPa (29.0 psi). 2. Engine coolant temperature between 65?C (149?F) and 100?C (212?F). 3. Engine Speed between 400 rpm and 2000 rpm. 4. Engine torque between 50 Nm and 3000 Nm. INHIBITING THE DTC: 1.
