The same. 3.6 engine starter red cable goes to the under hood fuse box battery terminal stud. The dirty orange wire is the fusible link for the alternator on the cable that goes to it.

Both relearns using a capable scan tool.

Try the the throttle body relearn function.

So what resolved this issue?

The P0016 code needs to fixed first. The PCM is seeing the camshaft position out of phase with the crankshaft position. The PCM needs the timing to be correct to determine spark and fuel for the engine. Causes: Sensors and wiring Mechanical timing chain and camshaft VVT solenoids. Using a capable scan tool, the cam-crank relearn must be done. It's done engine off. Using the scan tool you can check if the cam crank sensors are in sync. The scanner may point you to a problem with a sensor. The cam crank sensors must be in sync. After that if the code is still present and the engine doesn't start. You will be looking into the mechanical aspect. Timing chain and cam related stuff.

There is a cam crank relearn procedure on a bidirectional scan tool. That has to be done to get the cam and crank sensors in sync.

I was unable to jack my vehicle off the ground. So, I cut through the seal from the inside.

To answer your questions regarding the grounds on the driver's side strut tower. On the large stud is a 2 gauge cable to battery. 2 gauge to the engine block ground stud. On the middle stud is 4 gauge ground to the engine block somewhere. I did that first before upgrading everything. Just left it on.

Hello, First, when I did this work, I had too much bulk cable and time and got a little crazy. First check out my thread on the battery below. https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/ A realistic ground upgrade would be this. Passenger motor Mount to strut tower ground studs. This is a weak ground. - 4 or 6 gauge cable to replace small ground wire. - mending bar or wire stud to stud. Driver's side strut tower battery ground stud. - 2 gauge cable from this stud to the engine block stud. Next to the electric vacuum pump. You need ⅜" size lugs on both ends of the cable. -Running a cable inside to the factory stud on the passenger side kick panel. To the right of the glove box. -A cable to the bolt to the left of the cabin air filter. That is all you need. I wish, I knew the length of cable to the interior. I don't.

Underhood battery connections below. Negative terminal large stud on the strut tower. Positive cable connection on TIPM under red cover.

Dodge journey service information. P0600 serial communication link. -PCM detects internal failure. -Check PCM connectors and grounds. Clear codes if it returns, Replace PCM. This is the battery negative ground on the right large cable. The PCM grounds through one of the 2 small studs. Check these and clean.
