Fault Code P0401 what is the most common resolution to this, the replacement of the egr valve or the egr valve pressure sensor?

P0401 and P0402 I think have to do with the EGR Valve and EGR Sensor-However even though its one of the EGR problems" P0401" it is better to buy the sensor and the EGR Valve b/c you don't want another EGR problem again.-but I strongly suggest that its the EGR valve.-sensors are usually the next break down-"a employee's friend at autozone has a mustang". or someone came back b/c of another problem occured later.-autozone knows the codes so as them.
