Hi- I had a friend do a diagnostic on my 2004 Liberty. It showed a code
P0122. Turned out it was referring to the 'throttle position sensor'.
Can someone send me a site where I can learn how to change it myself?
It can't be that difficult since it's somewhat close to the top of the
engine. Thanks, jmc

It is right on the throttle body, on the RIGHT side, a three wire connector.

There should be only two screws that hold it on, so unplug the harness, and remove it to replace it.

REPLACE:
Install TPS and retaining screws.
Tighten screws to 7 N-m (60 in. lbs).
Manually move the throttle to be sure there are no bindings.
Replace air hose.

TESTING:
Off-Idle .06 Volts
WOT 2.608 Volts above learned idle.

0.26 Volts Minimum.
4.49 Volts Max WOT

The TCM only supplies 5V to the TPS, so it can't go higher than that.
