Welcome aboard. Please read this- https://www.dodgejourneyforum.com/topic/18760-journey-maintenance-and-other-fun-facts/

2016, 3.6L 135k When, I got my DJ. I knew it would have electrical issues. Because of the 4 gauge battery and electrical cables. The only other engine to chassis ground. Being the very small gauge wire on the passenger mount. With all it's electronic modules (12-14) it needs plenty of good grounds. Bad grounds cause all kinds of strange problems. I went with more grounds the merrier for my DJ. At a minimum if people would add a 2 gauge cable. Negative battery stud on strut tower to engine block stud. 4 gauge cable from the engine passenger mount to the strut tower studs. They would be good to go . Cost wise pretty cheap to do, for the added reliability. So, I posted these threads- https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/ https://www.dodgejourneyforum.com/topic/18374-electrical-system-fyi-ground-system/ https://www.dodgejourneyforum.com/topic/18296-charging-system-101-with-diagrams/ I believe in building a good solid electrical foundation. Easiest upgrade to do yourself. Which, would eliminate some problems. Then narrow it down to troubleshooting the specific load ( module, light etc.) Connections and the very small wires throughout the vehicle . It's too easy to get focused on a part, and miss it being something simple. Causing the actual problem. Well, to be honest cut down on repeat forum posts! Dean

Yes. Now is the perfect time to do it. The Dodge spec of 120k miles is just crazy. 60k miles is a safe bet. Too keep it running right and last as long as possible. People let it go too many miles or do not service it at all. It starts to to get expensive after that. Even, if there is any kind of warranty on it. Get it serviced.

I found this on YouTube. Eric O., South Main Auto. Heater core flush using CLR on a Journey. https://youtu.be/LtnVyFNyU1w?si=uXpf8K_FffQeEqJ3

Hi 5R9, Would you post a picture of your spliced connections on the heater core tubes?

Fluids and basic checks Know what specific type of fluids your year Journey uses. It matters. The reservoir tanks and dip-stick are marked for correct fluid levels. They have yellow caps on them. See pictures at end of this post. 1) coolant level. 2) power steering fluid 3) engine oil 4) brake fluid 5) windshield washer fluid 6) Transmission fluid - if your transmission has the dipstick tube. You will need to buy the dipstick. Read my post and thread here on the Forum. https://www.dodgejourneyforum.com/topic/18151-automatic-transmission-fyi-please-read/ Tire pressure. Consult label on driver's side door jamb. Heater hoses. The Journey has a lot of heater hoses. You should definitely check for leaks. If you have the rear seat AC-Heat controls. There is 2 heater hoses that run from the engine bay. Underneath the passenger floor boards through metal lines to the rear heater core. Then connect to that heater core with rubber hoses. Cabin air filter. Located behind the glove box. EVIC screen located in the center of the instrument cluster. Use the keypad on the left side of the steering wheel. Arrow buttons and the back button. Explore what things you can display on the screen. V6 3.6L engine info. The engine oil filter is located on the top of the engine. Beneath the twist off cap on the engine cover. The oil filter housing and the cap you remove to change it are plastic. If over tightened, the housing will crack and cause an expensive oil leak. Wherever you go for oil changes. You better talk to them so they know all about it. The Journey has a lot of things going on under the hood. That you should monitor and know about. The more often you check your fluids and look around the engine bay. You can catch problems and fix them at your convenience. Before you get stranded somewhere. Dean.

Owners manual 2016.

Go with a cigarette lighter-power port adapter to USB.

Welcome! First thing, you should do is a correct transmission filter and fluid change. Do not wait. The transmission correct service is often neglected. Dodge recommends 120k miles. Your on borrowed time at that mileage. Here is a post, I put together on everything regarding that. https://www.dodgejourneyforum.com/topic/18151-automatic-transmission-fyi-please-read/

Go to Rockautocom. For research it is excellent. Look up your DJ and read through brake pads. Different variables for rotor size and vehicle production date.

Does your steering wheel have the top 2 keypad buttons as seen in the picture below? The VR button, phone button?

Happy to! Do this. For you, get a standard 2 gauge ground cable. Run it from the battery ground stud on the driver's side strut tower to the engine block. The DJ has a weak electrical ground system. Here is my post that explains it entirely. https://www.dodgejourneyforum.com/topic/18374-electrical-system-fyi-ground-system/ Here is my post regarding necessary battery maintenance and upgrades https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/ Dean

You have an engine vacuum leak. The no power brake booster and these codes are vacuum leak related. Trace vacuum lines from the map sensor to the brake booster and the engine source.

You need to have a bi-directional scan tool. That can communicate with all the modules and test individual components. Perform relearn procedures. I have this one- LAUNCH X431 CRP919EBT Elite... https://www.amazon.com/dp/B0C68BKGN3?ref=ppx_pop_mob_ap_share Please scan for codes and tell me exactly. What they all are right now.

When you replace cam position sensors and the throttle body. There is a scan tool relearn function, that has to be done. Start here.

Life issues. Say no more, I know. So what all have you replaced so far?
