Our cars use a MAF sensor, so I'm not sure there is a MAP. If you know the air coming in via the MAF, you don't really need to know the pressure in the manifold. MAP sensors are generally used on speed-density systems.

MAP sensors are generally used on speed-density systems. Aurora40, Actually, the 4.0L V8 does have a MAP sensor. In fact, it has a MAP (manifold absolute pressure) and a MAF (mass air flow) sensor. I looked this up in my 2003 factory service manual. For the V8, the MAP sensor is located on top of the intake manifold, right after the MAF sensor. I know that this is the forum for the 3.5L V6, but I wanted to inform you about this. As for the V6, I am not sure if it has a MAP sensor or not because I do not have a 2001 or 2002 service manual. I would think that it would being that it was designed from the V8 architecture. Perhaps someone who has a 2001 or 2002 manual can check it and let johnj1277 know? skexius |

Well the place changed the map sensor. But the code that keeps coming up now is the secondary air sensor...They said the part is 275 thats not labor....does anyone know anything about that sensor?
