Common Faults
A clogged EGR (Exhaust Gas Recirculation) passage can significantly impact your engine’s performance and emissions. Common symptoms of a clogged EGR passage include:
- Rough idling: The engine may struggle to maintain a steady idle speed.
- Reduced fuel efficiency: Increased fuel consumption is often linked to a malfunctioning EGR system.
- Increased emissions: A clogged EGR can lead to higher NOx emissions, potentially causing your vehicle to fail an emissions test.
- Engine knocking or pinging: You may hear unusual noises from the engine due to improper combustion.
- Check Engine Light (CEL): Fault codes related to the EGR system may trigger the CEL.
Addressing EGR passage blockages is critical for maintaining emissions compliance and engine health.
