What causes p0401 code?
What causes p0401 code?
Code P0401 is triggered when the EGR temperature sensor does not see enough of a temperature change when the EGR is commanded to open. These sensors tend to get a lot of carbon buildup that causes them to lose sensitivity to the heat from the EGR gases.
What is OBD code p0401?
P0401 is a common OBDII trouble code that’ll pop up in the Ford Explorer. It has to do with the emissions system and stands for: P0401: EGR → Insufficient Flow.
What is Ford p0402?
P0402 is an OBDII trouble code that’ll pop up in the Ford Ranger. It has to do with the emissions system and stands for: P0402: EGR → Excessive Flow Diagnosis. The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output.
What is the OBD p1404 fault?
OBD II fault code P1404 is a manufacturer specific code that is defined by General Motors (Chevrolet in particular) as “Exhaust Gas Recirculation (EGR) Closed Position Performance”, and is set when the actual position of the EGR valve pintle does no coincide with the position of the EGR valve pintle the PCM (Powertrain Control Module) is expecting to see when the EGR valve is closed.
