Exhaust Gas Recirculation Flow Excessive Detected

Select a Code:


po402,rubs rough,starts hard

Looks to be a problem with the EGR which is the Exhaust Gas Recirculation. Three basic components of the EGR are the: valve, solenoid, and a differential pressure sensor. You should check the sensor to make sure its working correctly, make sure the EGR isn't clogged and check and make sure you're getting a good vacuum seal.
