  2. So if I create suction on the MAP sensor, the resistance between the sensor output pin and sensor ground pin should change, correct? If it doesn't does that mean the MAP sensor needs replacing?

    1. Sounds logical to me, yes. You could always try the same with a MAP sensor that you know is working and see if this holds true, assuming you're replacing it because you've been experiencing engine problems.

  3. I P sensor with a used one and it ran fine, the following day however the same problem started again,( engine died when stopped at a light and did"nt restart for 5 or 10 minutes), any ideas if there might be something else causing this to happen ?
