oil pressure switch location?

So oil pressure was good, now drops to 0 with check gauges light on when idleing t light after warmed up. Sometimes gauges works, sometimes does not. Reads just under 40 or so when driving when it's acting up. Been driving for a while like this, no motor noise.

Where is the switch exactly so I can replace it? tools needed? i already have a new switch.

99 grand cherokee 4.0

Should be right above the oil filter.

Actually in the 4.0 it is between the oil filter and firewall on the passenger side of the block.

Word of advice. Take the oil filter out. It makes the job much easier. Also don't forget to slide the little red tab before you get it off.

Get it from the dealer....have had problems with other ones.

would this switch cause the gauge to be pinned all the time?

Mine would go down as soon as the engine warmed up or I came to a stop. It would read regular when I was on the gas.

You could actually have more of a problem then an oil pressure switch. I would start there and see what happens.
