Mazda Protege Problem Report

Mazda Protege Check Engine Light Due to Restricted EGR System

(13 reports)

The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.

Didn't need to be replaced. Pulled it out and cleaned the inside. Check engine light has not come back on since. I have gone about 4000 miles since then and still good. -
