My check engine light is on, and the code it returns is for the EGR valve. The AutoZone computer tells me this:
EGR system fault
The ECM has detected too little flow on the EGR System.
The AutoZone person told me that the valve needs replacement.
The dealership mechanics told me that replacing it would be a waste of money, and that the system only needs decarbonization. Would cleaning the system be enough to turn off the Engine light (and therefore pass inspection)? Thanks for the help!
