When you see the fault code 0401 on your Ford Ranger, it means that the Exhaust Gas Recirculation (EGR) flow is not enough. Several factors could lead to this problem, but the primary suspect is often a malfunctioning DPFE sensor. This sensor, which measures the delta pressure feedback, can fail and give inaccurate readings of the exhaust flow. Another possible culprit is blocked EGR ports in the intake system. The EGR valve is responsible for allowing exhaust gases to mix with the air fuel mixture in the intake manifold. Lastly, a clogged exhaust gas orifice or a tube with a hole could also be to blame for the 0401 fault. It's advisable to seek assistance from a professional to accurately diagnose and address any other underlying issues that may trigger this fault code.
