What does p0402 stand for in Ford Ranger?

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 causes the p0402 code on an EGR?

Code P0402 is triggered when the EGR temperature sensor sees more of a temperature change than the EGR has commanded to open. This is usually caused by the EGR backpressure control valve getting a burnt diaphragm from the exhaust backpressure over time or from a partly blocked catalyst. Need help with a P0402 code?

What does insufficient detected code p0401 mean?

Exhaust Gas Recirculation (EGR) Flow Insufficient Detected Code P0401 Meaning The exhaust gas recirculation (EGR) recirculates small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides.

When to use the Check Engine light p0402?

EGR is only needed in limited amounts under certain driving conditions. If the PCM detects that there is excessive EGR flow, it may turn on the check engine light and trigger code P0402.

What does the DTC p0402 stand for?

Diagnostic Trouble Code (DTC) P0402 stands for Exhaust Gas Recirculation “A” Flow Excessive Detected. It indicates that the powertrain control module (PCM) has detected excessive EGR. It is one of the generic diagnostic trouble codes in a number of makes and models that are related to the vehicle’s EGR.

EGR is only needed in limited amounts under certain driving conditions. If the PCM detects that there is excessive EGR flow, it may turn on the check engine light and trigger code P0402.
