My manual 95 240 with stock ka engine has had the CEL on for nuetral position sensor, I was getting tired of looking at the light so I finally got around to changing it. I think it was the sensor nearest to the shifter on the top right of the tranny. I reset the ECU and it seemed to go away but 2 days later it came back. What else could it be? or what can I do to test it's working? Thanks
