Frequently Asked Questions
Q: Can an EGR fault be caused by more than the valve? A: Yes. Wiring, sensors, blocked passages, the EGR cooler, intake deposits, and engine-management faults should also be diagnosed.
Q: Is this an original OEM part? A: This is an aftermarket replacement; brand names and part numbers are used only to identify compatibility.
