Need a wiring diagram for map sensor in 2006 Jeep Liberty 4x4 3.7L


Go to autozone and ask for the wiring diagram. They will print one for you for free. If you dont have an autozone near you try another parts store. If you purchase a haines of chiltons manual ($25 in a retail store or $18 on amazon), it will have a detailed wiring diagram of the MAP sensor.

Good Luck!

The age of your vehicle guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers(pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive.

Have you hooked a scanner to the computer and checked the oxygen sensor(s)? If they are bad they could lean out the engine.

Also, a restricted exhaust system can lower engine performance. If you dont know old the plugs and wires are, replace them. With plug wires, its the age not the miles. How old is the coil pack? It could be "breaking down" at higher rpm's. Does your engine have a cam sensor? It would be located where a Distributer used to be on older engines.

Remember an engine needs three things to work properly...Air / Fuel / Ignition(Spark)

MAF sensor if bad, the engine may not even start let alone run.
MAP sensor on most Olds engines is located just behind the rear valve cover. It may have a 3 or 4 wire plug connected and a vacuum line. Its about 1 1/2 inches tall X 4 inches long X 3/4 inch thick.
Hope this helps and good luck!

Nothing electrical works on rear door wiper, licen


Open the rear hatch and look for the wiring harness that goes into the door. Inspect the harness for cut or damaged wires. Also look for failed fused links. These are wires that are design to fail when the circuit is over loaded or shorted. They serve the same purpose as fuses but usually more than one circuit is wired thru them. If you dont find anything wrong then you will need to aquire a wiring diagram to further trouble the circuits.

Runs fine off idle but at idle with AC on the engine misfires


theres alot of 2002 chevys of different kinds but they all can get a vacume leak the 3.1 and 3.4 even the 4.3 and the 5.7 blow intake gaskets. un plug the pcv valve and the vent hose from the valve cover to the air cleaner hose. plug the holes good with tape and rags till sealed if it runs smooth ar idle then the intake is leaking. Coming into cold weather I did then as fast as I could as there was always another one in the parking lot. Leak coolant too. about half and half, some both. a few were driven too far they were blown. Plug wires and injectores dropping out will do it too. but check engine light on with codes P0300 or any code P0301-308. Vacume leak can set all kinds of stuff from map senser, cam senser Egr back pressure, ramdom cylinder miss to certain cylinder miss. and the leak will be the problem not the sensers or wires
