My car runs absolutley fine. But at around 1500 rpm the check engine light comes on. It doesn't come on EVERY single time, but most of the time. It then shuts off usually around 2000 rpm. It doesn't matter if it's part throttle or full throttle, it still comes on. I pulled the codes and got a code 31.
I checked the EGR valve and it's fine. So I'm thinking it's the EGR valve position sensor. Would this make sense? I want to know before I go out and buy the new sensor. Is there any way to test the sensor? Any help is appreciated!
