The EGR valve can become clogged with carbon, which causes the Check Engine Light to illuminate. The valve needs to be removed and the system cleaned.

    Check engine light came on. EGR valve replaced. After a few months check engine light came back on. Mechanic said EGR hose was now clogged. Could unclog hose but the heads may still be clogged and cause the check engine light to come back on. Won't pass inspection in current condition.
