Map sensor connector
The connector to the map sensor on my 4.7 is totally broken and the wires don't seem to be connecting well throwing a p0121 code and causing my wj to stall. I taped it up but that only fixed it for a day or two. Should I try to find a new connector somewhere or can I just bypass it and wire it straight to the sensor?
No it's behind the alternator attached to the intake manifold. I used a 20 or 25 torx bit and a 6 inch extension and it was still tough to get it out. Just look in between the alt and the AC unit and you'll see it attached
I had a similar problem in the spring. I replaced the sensor but broke the wiring connector. The new sensor didn't seem to work. Eventually I found that the rubber elbow that comes out of the back of the map sensor and elbows into the throttle body had a small crack in it, causing the code and for the truck to stall out if I wasn't on the gas. I have the 4.0 but it wouldn't hurt to check this because I overlooked it and it was a really easy fix.
