[Hyundai tucson]

Hi we have a 2007 Hyundai Tucson it’s recently had a new EGR valve fitted its not a genuine EGR valve I guess it’s now developed a slight miss on start up it does not idle smooth the revs drop a bit and it seems too smoke several people say the egr valve needs coding or calibrating to match the ecu ? Any ideas
Thanks

AFAIK, there isn't any position feedback sensor on the Hyundai EGR valve, so it won't need any calibration/coding. You can tell if there's a position sensor by counting the number of wires on the valve's harness connector. There will be (usually) 5 wires if there's a sensor built into the valve and only 2 wires on a valve with no position sensor.

Why did you replace the valve?
