Way to Test Air Mass Sensor Off-Engine?
2003 C230 Kompressor, had check engine light, did online research, gambled that air mass sensor (mass air sensor?) was bad. Wrong guess: cost of part plus $200 labor later, still CEL. Turned out to be a valve guide/seat problem on cylinder #1, nothing to do with any sensors.
So am now trying to sell my original, apparently still just fine sensor. Have a prospect but he justifiably would like some assurance from me that the old sensor is still good. (Only has 47k miles on it and was NOT the cause of my CEL, so I presume it is, but in his position I'd want more of a guarantee than that myself).
Anybody know a way to test the used sensor without having to put it back on the car?
