and have that alt checked as well by a auto shop
 

Sounds like you need a new battery. 

You should reference your owners manual. It contains the manufacturer recommended maintenance intervals. 

Good example of what a bad rocker sounds like.
 

My 2013 has just over 80k and brakes look great. However the rotors are a another story. Slightly warped and grooved. Nothing to warrant a replacement but it's there and felt under heavy braking 

Without using test equipment we would be guessing. If it was a remanufactured alternator 3-4 years ago, I would think it’s probably the cause.  Charge up battery first and load test it. Then run car and see what alternator does. Measure voltage loaded and unloaded etc.
There is a huge fuse that protects electrical system from bad alternator doing any damage.  Even batteries seem to last shorter than a few years ago. Lots of load with all the power options, most cars have 160 amp alternators now. Typical car in the 1980s was probably 80amps.

Reading that i was like... have you been watching me do my plugs?!?! ? ? ? 

Most common mistake people do is start with the worst case scenario. Start small then work up frim there. Otherwise you'll end up replacing the engine each time the air filter gets clogged.
 
The smallest things sometimes cause the biggest problems.

YUP, I agree with you ! AND it does not comprehend that it's been a "done deal" for 8 months and NOT just a possibility if it had scanned the whole thread of my posts here.
But I must also say that there's not much to be done about it, our moderator has asked for help and nobody has stepped up. I can barely do posts and beyond TYPING, I'm lost as to linking in photos or other info from the site to a posting....In other words I'm barely computer literate.
On a side note that we all be truthful, the '11 is now titled and insured in my son's name and resides at his home in the next town away from our home. So does this mean that I'm actually back to a 2 Journey family ? Yes I still "spearhead" the maint. work that it will require. IF he thinks something's wrong, he calls me. At least he has learned to check the oil and refill the washer tank!

And I quote  … “Ensure the chosen vehicle aligns with everyone’s satisfaction.”  Although technically proper english, almost no one normally speaks like this.  But the ChatGPT or Chatbot what ever, is getting better.  Robo-Johan has almost the  same reputation rating as me. I wonder if I should even bother posting anymore. ?
And the chatbot apps unlike the rest of us…are getting paid, some how, hilarious. 

@Locosiete @2late4u it was definitely (so far) just the hose clamps needing a little tightening! What a relief, thank you guys so much!!

There is a dealer ecm flash update for 2015-2017 Journey for nuisance oil pressure codes mentioned.
The poster from United Arab Emirates might have a issue getting update done. Even if pressure is ok, the codes might still trigger limp mode type issues. 
 
Pressure sensor harness is underneath intake manifold  between the cylinder heads on the oil cooler assembly. Lots of heat there, oil if it seeps a bit. Horrible place for access and wire trouble shooting.

Not really sure of what you are saying in the posting other than from the title of oil pressure trouble.
 
The engine oil pump is a 2 stage pump, unkie most other motors. It has been sort of problematic for a number of 3.6/3.2 engines. BUT it will set OBD trouble codes/ Check engine light for at least 2 different problems. Those are P06DD and P06DE
Both mean a new oil pump in the majority of cases. BUT I agree with putting in a new oil pressure sensor first. 
I did not post of my own oil pump code on the forum here, but recently on my '14 Journey had the P06DE show up and immediately had the oil pump replaced. cost me almost $600. US dollars. Most of that being the cost of an OEM pump and not an aftermarket supplier.
 

Get the battery tested and replace if needed.

oh well 152k and still going strong on mne

@Locosiete @2late4u awesome thanks for the tips! I will be bringing it into my shop later this week when the extreme cold warning is done. Will be sure to post how it goes!

I would def try to tighten the alum ridges that clamp around the tubes just be carefully,as mentioned above the tubes are sensitive to any movement, I wouldn't try to replace the o rings as they should still be ok

Welcome to the site. Push button start very sensitive to getting full 12 volts to function. Battery warmer pad  rather than block heater would probably help.
 
Need a very strong battery at your temps, if it’s more than 3 yrs old or alternator weak you will have problems.  Cranking amps on battery and voltage output from alt need checking. BMS systems on newer cars might get in way where you are;   sees low voltage from cold and interprets as draw from item left on. Shuts system down. Sensor right at negative terminal of battery I think sends signal to pcm. 
 
Key fob has driver door lock key built in. Little tab releases key. May have to lube with deicer etc first time used. If fob battery dead or low, press end of fob against start button directly. Use it to cycle button,  signal gets picked up. 
Portable lithium booster packs , biggest you can find , helpful this time of year.
 
 
 

 

looks like a cover for an air vent from the underside of your car ,crawl under where you found it and look around should be easy to find where it goes back also you could take it to your local dodge dealership and they would be able to tell you where it goes or any auto body shop should or could tell you as well if they want to help.please report back on what you find out    I have never seen one on a dodge journey BUT pickup trucks usually  have one located on the rear wall near the floor of the cabin to let air out of the truck cabins so the ac/heat work properly

The one on the right side of the cabin filter is the recirculate actautor.That's the one that causes fogging when it gets stuck in recirculate mode.

mine just done this but was stuck in the heat mode, drop the glove box door and then push the black fabric cover so you can see the blend doors there is one to the left side of the opening  which controls the different levels ( defrost floor and regular vents) of the air is sent ,the one closest to it on the right, is the one causing your trouble if you move the passenger side temp up and down it should be moving I just tapped on mine and it then started working and haven't caused me no more trouble now there is another one on the right side of the air filter don't know what that controls............
 

thanks for reporting back on the fix ,,,,that is what makes a blog help other folks,,, Have sa great New Year

yes new parts can be bad, return it to o'rileys and they should replace it for you,, from your statement was it more than 1 senor? are you sure you replaced the right one? no problem driving with those lights that are on you just wont have abs braking just regular style brakes and also NO cruise control...I haven't been driving with those lights on for about a yr/and half while waiting on the dealership to get me a new abs module that are on backorder everywhere no one has replacement module,,,also you could have a bad wheel bearing as well causing your problem with that sensor showing bad but could be the wheel bearing...good luck
