On older cars operated by engine vacuum, the EGR valve diaphragm can deteriorate and leak, causing a rough idle and a check engine light. In that case, the valve should be replaced. Also, over time the valve can accumulate carbon buildup and stick open, causing a rough running engine.
Why would an EGR valve need to be replaced?
On older cars operated by engine vacuum, the EGR valve diaphragm can deteriorate and leak, causing a rough idle and a check engine light. In that case, the valve should be replaced. Also, over time the valve can accumulate carbon buildup and stick open, causing a rough running engine.
What can trigger an EGR code?
Clogged EGR passages. Faulty EGR valve. A failed sensor (e.g., differential pressure sensor, manifold absolute pressure sensor, etc.) Inadequate vacuum supply to the EGR valve.
