CEThomas Posted April 27, 2007 Share Posted April 27, 2007 What all does the MAP sensor control in the 2.5? I replaced the MAP sensor in the MJ last night and now I have more problems :headpop: The old one we had to unplug and just leave the vac hooked up to the sensor keep the engine running, know it was bad as we tested in my daughters olds and it did not work in it. Now we put the new one in it last night and it starts backfires and dies right away. Can not keep it running :mad: Tested it in the Olds and works fine. Hook the old one back up on vac and it starts and runs :nuts: So got a feeling something else is also out :headpop: Charles Link to comment Share on other sites More sharing options...
87manche Posted April 27, 2007 Share Posted April 27, 2007 map sensor tells the computer how much air the motor is ingesting, so it's crucial to A/F ratio. sure you got the map plugged into the right hole? IIRC there's two ports, one is blocked off, the other is the actual vac port. Link to comment Share on other sites More sharing options...
