does anyone have a wiring diagram for the map sensor of 99 Cherokee with 4.0 I have 5v on both power and signal wire with plug disconnected trying to locate short

 

Note from DJ
Here is a link to a thread from 4-15-12 about a 98XJ with similar problem.
Test information goes on for two pages then refers you to another tread for the final solution.
Hope this information helps.

98 P0107 CEL code MAP on 4-5-12
The code says "Manifold Absolute Pressure/Barometric Pressure Circuit Low Input".

Note from DJ
More information on your possible short point on the MAP wiring.

XJs have a known chafing point where the harness is damaged.
