Oil pressure

I just drove my Jeep on my lunch break and noticed the oil gauge was high. After I sit at idle, it still reads a little high. Where should I start the trouble shooting?

Lubrication systems have a bypass valve that only filters some of the oil as it passes by the filter. Sometimes they can stick resulting in higher than normal pressure. I would change oil and filter and keep an eye on it.

I'll give it a try, I've changed the oil every 3,000 miles. I'm about 1900 miles into this last one.

At least it's not on the other end of the gauge. I have a 96 chevy dually with the 454 and 197k on the clock it still runs at 80 on start up and holds 60-70 after she's warmed up.

I have also read posts that the sender was a problem part. Either confirm what the pressure is with a mechanical gauge or go ahead and replace the sender

(note, I don't remember after what year but the gauges on later models is really a dummy indication and does not show an actual pressure)

I believe the 02's show actual pressure(I believe) but for $50 I'll replace it anyway.

I do not like aftermarket electrical parts, most are junk from china. I only use electrical parts from the dealer.

Just unplug the sensor. There's a pressure clip on both sides. Push in and pull out. Then unscrew the sensor itself from the block.

There is a red tag on the plug that needs to be pushed toward the front of the Jeep(I pryed it with a flathead screwdriver), it will then slide right off. Use a 1 1/16 deep well socket to remove the plug
