Check Gauges, No Oil Pressure

This is regarding a 2005 Jeep Wrangler.I have an intermittent issue, after driving for 10 or 15 miles, when I come to a stop, the check gauges alert comes on with a series of beeps and the oil pressure drops to zero. At soon as I get over 1250 RPMs, the oil pressure goes back to normal and the light goes off. But if the RPMs drop below 1250, the light comes back on and the oil pressure drops again (no beeps). It will do this every time the the RPMS go below 1250 until I shut off the engine, then it is fine for a period of time. Oil level is fine. No change in performance when this happens. Any thoughts would be most appreciated!

The oil pressure switch on the engine is probably bad and needs to be replaced.

Or, you could really have low oil pressure. This can be tested with an oil pressure test gauge that can usually be borrowed from most auto parts stores.

Find & install a Mopar oil pressure sender, there's 99% chance that is all that is wrong. Avoid the cheap aftermarket oil pressure senders like Autozone sells, odds are not good you'd get one that worked properly the first or second time. It took 3 Autozone oil pressure senders in one day for me years ago from Autozone before I finally got one that worked properly. Never again.

Jeep's connectors are a different type of beast, that is for sure. I've been in the electronics industry for 50 years and have never seen a connector style more difficult to master than what is in our Jeeps. The short answer is I don't have a good answer as I haven't figured them out well enough yet to consistently be able to disconnect them without some kind of a struggle lol. I guess they don't want them coming apart accidentally. Basically you slide the red tab over and that releases the center tab but that makes it sound easier than it usually is, at least for me. I have to 'mess with them' to get them apart half the time.

I've found that spraying them with WD-40 makes them come apart easier.

Okay, fresh from fooling around with this thing. If you have the red tab or release, it moves side to side, or up and down, depending on how your sender is clocked, then pull the connector straight off closest to the where the wire is. Then you are free to do the sender dance. I found access is best from below, or rest your hood on the windshield header
