    Change MAP sensor - What can go wrong?


    I've had a slight problem with my opel astra 1998 model which was diagnosed to be a faulty MAP sensor. I went and bought another MAP sensor with the same serial number. But when I bought it, I found out that it has 2 numbers: one 8 digit number and another 4 digits number. Do both have to match or is just the 8 digits number enough?

    The numbers are: 90225716
    and 4-869

    Each number is written on a different corner at the bottom of the MAP sensor. If I tried the wrong sensor, what could go wrong? How should I change it? e.g. disconnect battery....etc

    Any suggestions would be very much appreciated.

    Just unplug the old one and swap it over.
    The truth is always the truth even if you haven't realised it yet...
