Hello every one, I have a 1997 pathfinder 3.3l 4wd, where is the map sensor located and how do I change it?

What problem(s) are you having with the vehicle? Have you had a diagnostic scan done to check if any codes are stored in the computer? If so, what codes did you get?

It will be either mounted on top of the throttle body or on the firewall, with a hose going to the throttle body. It likely has a 3-pin connector going to it. They are, however, a very reliable and expensive component.
