P1407 Fault Code: Understanding The Description And Troubleshooting Steps
The P1407 fault code indicates that the exhaust gas recirculation (EGR) flow is outside the self-test range. The EGR system is responsible for recirculating a portion of the exhaust gases into the intake manifold to reduce combustion temperatures and NOx emissions. During the Key On Engine Running (KOER) self-test, the EGR system is commanded ON at a fixed engine speed.
If the measured EGR flow falls above or below the required calibration, the test fails and the P1407 code is triggered. This code signifies that the EGR flow is not within the expected range during the self-test.
