How would you handle this (check engine light)?

is 85psi a typo?

That's what I was wondering. Cuz I could only get up to 49psi

I was wondering the same thing.

Granted, my data is limited to the functioning of a healthy 2.0T, but...its oil pressure usually hovers at 18 PSI or so when idling or at steady-state cruising on level ground.

On ascents and/or during acceleration, the pressure will increase to ~49 PSI, fluctuating only slightly and then only as long as conditions (including driver inputs) requires.

That's where mine are too. So I assume that means my oil pump is ok....? I have ordered the sensor and will install when it arrives (Assuming I can find a video on how-to)

What engine is in your Jeep? If a 2.0T, I'd say your observed PSI range is acceptable.

lets see what they have to say. maybe its 45psi. My guage has never and will never see 85psi

 

[hamiamham69]

Mine is the 3.6L

 

[NAZJeeper]

Mine is the 2.0

Speaking of which, does anyone know of a video showing how to replace the sensor? My searches have found nothing for a JL, only the JKs.....

So just took it out for a run, and it's working perfectly. CEL is off, it's idling at 16psi and gets up to 49psi when revved. If it were you, would you feel comfortable taking it on a 5 hr drive?

By way of example, a couple of years ago I assisted my neighbor as he chased down a recurrent CEL. He eventually determined that an emissions fitment adjacent to the fuel filler neck required replacement, but what a goose chase it was to get to that point.

Anyway, we observed that his truck, a Dodge Dakota (i.e., a Mopar product) would store the CEL codes in the vehicle's computer until the vehicle was driven at least 100 miles without the problem reoccurring...i.e., without the dashboard light illuminating again. Codes can be stored even if a consumer-grade code reader is used to extinguish the Check Engine Light.

With that in mind, I'd personally (a) carry a code reader with me, and (b) drive the Jeep at least 150 miles to ensure that (c) the CEL didn't reilluminate, and that my reader didn't pull any codes during that time, before taking the planned trip.

Just a suggestion.
