i recently had a check engine light on and ran a diagnoses and it came up as code 12, egr valve sensor. So i replaced it(egr brand new from honda) last weekend and cleaned up the egr ports as well, i also reset the battery too, then for a couple a days i drove the car, yet again the check engine light came on. I dont know what else to replace or diagnose? Any ideas?? Suggestions??

 

Bump.....Anyone?

 

Did you jumper the Blue two pin connector and make sure it is the same code again?
With the engine warmed up, you should be able to open the throttle by hand and watch for the EGR valve to lift as the RPM rises up around 1700 RPM.
If the EGR doesn't lift there is another problem with the vacum control circuit, or the lift sensor wiring.
