Oem or aftermarket filter?

Mine will drop to 20psi at idle (hot). Check your o rings on the filter? Or just change the filter

No idea what's wrong with your truck. However, if I may, a related suggestion: try typing your actual question/concern instead of relying on (what I assume is) text-to-speech. You may end up with something a bit more coherent. More people may then be willing to chime in.

Good luck.

Try reinstall the filter or replaced with another one. You will get low pressure if the output port oring or the bypass valve oring isn't sealling. Fully warmed up should be around 18-19 psi at idle. Aftermarket filter plastic cartridge material may be different than oem and could deformed under hot oil.

Simple things first. Double check the tightness of the oil filter to make sure it fully seated and tightened. Then what @Vtur said, replace the filter.

Mopar only sells the filter with a new cap for this reason. People were not installing the filter correctly in the cap. Is it possible that happened? Although it should have happened right away I guess.
Just a thought.

That's your problem. Doc's filters are garbage. Go back to Mopar or a different aftermarket brand.

It's a red flag when a company advertised a filter as high flow but the media cartridge shape and micron rating are the same as factory. Where's the additional flow comes from? Cellulose or synthetic media materials?

Most of them can advertises whatever they wanted knowing majority of the consumers has no ways of verifying and or testing their products.

Doc's doesn't even design or manufacture their filters. Their filters are sourced in different locations. I can't tell you how many times people have had oil leaks, fitment issues, and low-pressure codes when using Doc's.

Doc's is notorious for putting money into advertisements, commercials, and other clever social media pandering. They are just a reseller, not a true filter or oil brand.

I started having this issue intermittently after I had the HPFP replaced under recall (no failure, 62k miles). My gut feeling was that it had something to do with the software update they did at the time, as oil pressure in these vehicles is a triangulation of sensor data, not reliant on an actual oil pressure sending unit. If you were still under warranty, I would take it in and have it documented just in case you do have a mechanical issue. If you are outside of warranty I would suggest doing a full oil change with Mopar filter and sending an oil sample in for testing (blackstone or similar). If the jeep is running fine and temperatures look good and the pressure shoots up to a normal range a few seconds after the error, this is likely just a software glitch. When the error pops up, I would turn the vehicle off and then immediately turn it back on and see if it re-presents.

Obviously, if the jeep is acting strange in any way or running hot, you should not drive it or turn it on in any capacity. I would strongly suggest sticking with OEM filters sourced from a reputable place (not Amazon or eBay).
