Oil Pressure Sensor Help

i am having the problem with my 2002 liberty oil light coming on at stop lights. through the searching on this forum, it looks like the most likely culprit is the oil pressure sensor ....

can someone help me with some info?. ..... where is it located? is it hard to change it? how much is the part? .....

please let me know.



thanks!

Located just above the oil filter. Not difficult to change... took me 15 minutes or so, mostly because it's in an awkward location. Part itself is around $40.

Before you do all that, make sure your oil level is up to snuff. Not trying to insult your intelligence but it's worth checking if you haven't!

You'd be surprised. There's a thread on the XJ forum from a guy in Oregon who changed his radiator fluid and replaced it with straight water. It then froze solid with the recent weather and he wanted to know how to thaw his engine out. He then proceeded to ask what temperature water froze at. I'd like to think these threads are pranks, but the longer I live and the more people I meet the more I begin to think there's a whole segment of society that don't have a clue.

Anyway...disconnect the wire from the end of the sensor and use a wrench on the silver nut looking part of it to remove it. An open end wrench works best. It will take a while to get it out, and the new one in, because of the tight space. Lots of wrenching. But it is easy enough.
