Get some contact cleaner that is safe for plastic.
Before you spray the contacts, put some paper towel around and use a bit
of cardboard to keep any of the contact cleaner off of the paint. Contact
cleaner is very good paint remover. It's also a very good idea to wear
eye protection.

Disconnect the plug, spray the contacts, work them a bit with a
toothpick, spray again, let dry, then put a bit of dilectric grease
(sparkplug grease) in the socket and on the gasket. Then reassemble.


If your moderatly skilled with electronics and have a digital volt meter
you can test the TPS sensor. There are three leads. one is ground, one
is voltage, and the other varies as you move the throttle body.

Basically:
Turn the ignition on but do not start the jeep.
back-probe the connector and find the ground and +5v
(should be the outside two wires)
If there isn't 5v there then you might have a break in the harness
or just not a good contact with the wire.
Now measure the center wire against the ground.

Throttle butterfly Voltage
CLOSED >200 mV
OPEN <4.8 V

The transition between full open and closed should be smooth
with no jumps or dropouts.
