Exhaust Gas Recirculation Flow Insufficient Detected Ford F150. 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. Defective egr vacuum modulator valve.
Obd ii fault code p0401 is a generic code that is defined as “ egr insufficient flow detected”, and is set when the pcm (powertrain control module) detects a lower than expected flow of exhaust gas through the egr (exhaust gas recirculation) system. There is a factory service bulletin for the following ford models: Obdii.already replaced the egr valve.fault code what else.

Remove egr valve and check for blockage in the passages of the exhaust and intake. Egr solenoid valve circuit weak electrical connection. Diagnostic trouble code (dtc) p0402 stands for exhaust gas recirculation “a” flow excessive detected.
The Egr System On A Vehicle Is Responsible For Recirculating Exhaust Gasses In Order To Lower The Vehicles Emissions Output.
I had the code read at autozone and it said code p0401 egr insufficient flow. A code p0401 most likely means one or more of the following has happened: The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type.

The electrovalve beam of the egr system is open or closed. If those are clean, replace the egr valve. It has to do with the emissions system and stands for:

What The P0402 Code Means.
It is one of the generic diagnostic trouble codes in a number of makes and models that are related to the vehicle’s egr. Insufficient egr flow causing p0401 trouble code in computer. When no change in the flow rate is needed, the ecμ does not issue the pulse signal.
