P0401 Exhaust Gas Recirculation Flow Insufficient Background

Egr stands for exhaust gas recirculation and it does pretty much it’s namesake by rerouting a prescribed amount of exhaust gas back into the intake to be drawn into the cylinders to help reduce nox emissions. Exhaust gas is fairly inert meaning it’s already spent and does not help. When fixing this code, people quite often just replace the egr valve just to get the obd code. Egr passage clogged faulty egr vacuum modulator valve faulty egr valve faulty egr solenoid valve egr solenoid valve harness is open or shorted egr solenoid valve circuit poor electrical connection dead (weak) battery faulty egr temperature sensor and circuit exhaust gas leaks Exhaust gas recirculation valve defective;
