Why do I have an EGR code on my car?
Why do I have an EGR code on my car?
This is often due to carbon clogging passageways or improper operation of the egr-valve. However, we often find EGR codes on Ford products caused by inexpensive plastic parts that falsely report position to the control module.
What does the EGR error code p0401 mean?
In the shop’s defense, replacing your EGR valve probably would eliminate the error code, turn off the CEL, and allow you to pass emissions inspection. One thing is certain: the P0401 error code specifically means you have “reduced flow” in your exhaust gas recirculation system.
What should I do if my EGR light is not working?
The repair of this condition is removal of the EGR valve and inspection of the passageway to check for a blockage. Each model vehicle has different procedures for clearing the passageway due to many different configurations of the system. Some Fords have a removable tube.

Unfortunately, sometimes shop owners force their technicians to take the simplest, most obvious route rather than spending extra hours diagnosing a problem more thoroughly. In the shop’s defense, replacing your EGR valve probably would eliminate the error code, turn off the CEL, and allow you to pass emissions inspection.

Which is the correct formula for EGR error?
The EGR Error is also normalized for all types of EGR systems. The reading is based on a simple formula: (Actual EGR Position − Commanded EGR) ÷ Commanded EGR = EGR Error. For example, if the EGR valve is commanded open 10% and the EGR valve moves only 5% (5% − 10%) ÷ 10% = −50% error.
