I have a 2000 CHEVROLET EXPRESS 3500 7.4L V8. Where is the MAP sensor located? does anyone have any images/drawings that will show its location. I have looked all over the intake manifold and retraced every vacuum line, but still can't find it! The code indicated a bad MAP sensor, but I can't find one to replace?!?!
Thanks for the images. That was exactly what I was looking for. I failed to mention earlier in the post that the van just had a full tune up a few months ago. I'm planning on pulling the existing MAP sensor and bench testing it before I purchase a new part.
I'm just not familiar with these Chevy's...I'm more of a Jeep guy...specifically the 4.0 xj.
