ZJ 4.0 Oil Pressure Sensor twitchy meter syndrome
Pulling the wire sends it full scale, otherwise it tends to twitch to
full scale erratically every now and then. Wiring looks clean. Engine
ground OK, but bypassed anyway as a test--no help. Factory oil filter
replaced about a month ago, twitch didn't appear until about 2 days ago.
Do I need to drain the oil before swapping that thing or is there a
check valve behind it? For 13 bucks I'll swap it before I'll bother
pressure testing the pump.

That's exactly what mine was doing before it just started staying between
70 and 80 psi. I thought about taking it out and flushing with carb cleaner
but like you say, the replacement is cheap.

Draining isn't necessary. When I did mine there might have been a few
drips to wipe up but that was it.
I did put a little bit of thread sealant on the last few threads just
to stop any oil leaks.

Thanks Doug
It looks like it has a fairly low value on the pita scale...not as young
as I was last year.

It was easy. Only problem was space to move a wrench around.
Nobody is getting any younger even if they refuse to grow up. :)
Sittin here with my leg up on the computer. I found a camouflaged tree
at the company picnic today. While running to catch a frisbee I jammed
my small toes real good. Monday I'll probably have a Dr. take a look.
Haven't done something like this since I was a kid.
At least being older comes with a better stocked medicine cabinet and
there were some left over hydrocodone tabs. Right now I could park
a Jeep on my foot and not know. :)
