Confirm my suspicions??

2017 JKUR 3.6 w/52k miles.

@ my last oil change I tossed in 6 ozs of SeaFoam.
Figured it would do some good to clean things up a bit.

After about 100 miles I threw the
P06DE code. (Oil pressure sensor).

I was on my way out of town, vehicle was running fine w/o any low oil pressure symptoms. I cleared the code and continued my trip.

My suspicions are that the SeaFoam loosened some gunk that may have hindered the sensor.
After about 50 more miles the light returned w/same code. I again cleared it and continued driving.
50 more miles, same thing.

Iíve now driven over 750 miles w/o the code returning.

Iím not having any symptoms of low oil pressure. The Jeep is running fine.

Iíve ordered a new sensor just in case but Iím assuming it was gunk loosened by the SeaFoam, I think Iím good to go and probably have no need to worry.
Iíll replace the sensor next time I have reason to be under the hood.

Do yíall concur?

Edit:
Was on my way to Hot Springs for wheeling.
Drove most of the way there w/o code return.
Wheeled all day without it returning, and w/o any other issues.
Made entire trip home w/o issues.

The oil pressure sensor is under the intake manifold and attached to the oil filter housing. Unless they have changed the material of the housing I would suggest changing the whole housing as they tend to take a crap at around 65k or so.

my bet will always fall on the most rudimentary possibility when discussion includes the topic of these primative ecu's in these Jeeps goes; I'm betting the 6 oz of seafoam was just enough of a volumetric increase in oil sensor detection that the code was just that volume discrepancy being recalibrated ( ne: relearned) after being detected...

tho it could have been some particulate flushed by the sensor , I doubt that thing's sensitive-enough or its job isn't that precise.. to read in that manner ..unless completely inhibited ,yeah? l






(edit:
crap.
I just saw the " after 100 miles ..." detail. I think your diag is accurate,OP. )

I'd really bet the sensor has gone out. It's a notorious problem for the 3.6L.

I had it go out and it was exactly the same, it'd intermittently trip the code, then it'd work for days, then start tripping again. I replaced the sensor and never had a problem again (which is a real pain, do your spark plugs while you're in there).

52k miles? Is that enough to seafoam? Did you notice any improvement in performance?

*oops. Miles not km, good morning

Seafoam is not modified tech. It's snake oil tech.

IDK
Iím not an expert.

I run some Lucas fuel treatment about every 4th-5th tank.

I figured @ 50k it wouldnít hurt to toss in something to clean up the lower end and other oil passages.

SeaFoam seems to have a good reputation.

Iím not putting any blame on the product, what little common sense I have told me that itís possible that something in the process effected the sensor.
Like I said, I have no symptoms of low oil pressure.

Iíve ordered a new sensor, and as suggested Iíll probably order the filter housing as well. Iíll do the work next time I have reason to get the tools out.

As far as noticing any performance improvement?

No, and I wasnít expecting too. I simply thought it wouldnít hurt to clean things up a bit.

YMMV

I'm no expert either. I do know you want a little bit of resistance in the engine... not a ton of sludge that would accumulate over 200-400k then you may look at a treatment. I did at that time and it was noticeable improvement.

My bad Bro Tater.
Maybe a mod will move the thread read to a more appropriate forum.

In the mean time, is there a better product to clean up the places that engine oil goes?

Iíve always heard that SeaFoam is a good choice for said purpose.

If I get 200k plus out of this 3.6 Iíll be pleasantly surprised.

I donít abuse it but I surely donít baby it.
I try to take good care of my stuff but Iím gunna use it.

Dam, thatís almost a poem.

Just giving your daily ration of shit. I've never used additives. Back in the 90's I remember Slick50 being the big thing. The name "seafoam" gives me an instant soft-on for some reason. Now if they gave it a sexy name, I'd buy it.
