UPDATE: I've decided to sign up for Autoauth with my XTool and attempted to perform the crank/cam relearn....it was not able to do it. It did let me do the throttle body relearn and it passed. But then as I attempted to drive the vehicle there was no reaction to the gas pedal which was wild. I had to park it and do a manual throttle body reset (again) and then the gas/pedal was in sync. This is very strange and I'm not happy with this... Everything I have attempted to fix or etc, keeps coming back or cant complete the relearns or etc. Then all of a sudden out of know where I get another new code.. -Body Controller (BCM0 Code) -Occupant Restraint(ORC) B273413 -Instrument Panel Cluster(IPC) U010000 Lost Communication With ECM/PCM- I have no clue where to go from here, and no idea why random codes keep popping up. But hey the engine is running, there is no torque still (torque request denied code)...and the random brake signal failure is still there.

100% haha.

Still working on it, but the car is running. Also I am using the XTool any scan, I've been complaining that the relearns arent being allowed/performed and I just found out thats because autoauth or the bypass cables is REQUIRED to clear codes or do any special functions (relearns, oil reset, or etc) on any Dodge Chrysler 2018 or newer. THAT IS CRAZY, nobody told me that haha. I'm now getting the bypass cables and will be doing it tomorrow. I will keep you all posted.

After cleaning the Throttle body, the vehicle would not start, I then did a throttle body reset using the pedals/flicking light method and the vehicle started right up. (A little rougher idle prior to cleaning) but it leveled out after letting it sit and then driving for 20 mins. Even though the vehicle is running and driving, the XTOOL A30D scan tool is not allowing the crankshaft/camshaft and throttle body Relearns to be performed. This is driving me nuts, it also wont let me delete any codes. I'm also getting random ass codes like tire pressure sensor 3 & 4 failure even though its giving me appropriate tire pressure. See attached...The ones circled in green, those sensors or items that have been replaced....(The relearned cant be performed) JCJourney202608171334_260817_143154.pdf

Ok, I will go ahead and try that. I still didn't do the Crankshaft/Camshaft relearn, so should I do that first? And then do the Throttle Body relearn? Just want to make sure I approach it correctly: 1. Crankshaft/Camshaft relearn 2. Let car run 1-3 minutes (idle only, then turn off) 3. Throttle body relearn (then start car/idle for 1-3 mins) 4. Scan/delete codes if any. 5. Drive it around for 10-15 to see if any codes come back. Should this be my approach?

Sorry for the delay, I didn't address that entirely because it seems to still be a possible issue. But here is where I am...I went through multiple cam/crank sensors and still did not get it to start. Now we just went all in and replaced the cam/crank sensors with mopar and the crank sounded much healthier (no start) and did kick over a few times. We then went back to basics and followed up with the throttle body and opened it manually by hand and it officially started. It ended up running crazy rough, super aggressive with fluctuations between 500-900 rpms. Here is what through us for a loop, we ran the obd using a snap on OBD tester (most codes were gone) and ended up getting a MAF code so we replaced the sensor and after 30 seconds the engine started and stabilized. After driving around, the codes above came on. We went to autozone to see what codes they get and the original codes showed up as well....twice. P0016 — Crankshaft/Camshaft Position Correlation, Bank 1 Sensor A (Showed up twice) P0017 — Crankshaft/Camshaft Position Correlation, Bank 1 Sensor B (Showed up twice) P0008 — Engine Position System Performance, Bank 1 (Showed up twice) P000B — Exhaust “B” Camshaft Position Slow Response, Bank 1 (Showed up twice) C0021-02 — Brake Booster, General Signal Failure C121C-00 — Torque Request Signal Denied C212A-16 — voltage-below-threshold type fault U0401-00 — Invalid Data Received From ECM/PCM C2101-17 — another voltage-related chassis/ABS fault It now seems because of these voltages codes, we are getting all sorts of other random codes, mind you we had NO Brake issues prior to the cam shaft Crankshaft issues. We also never did the relearn. Any ideas on where to go from here?

Hey John, Thank you for responding. Yes, the brake fluid reservoir was a little under the middle so I filled it up but the issue is still there. I did order new brake pads and rotors and will be installing them this weekend. If the issue continues, what would you look at after?

As I was working on my vehicle (Previously had crankshaft/camshaft issues) all of a sudden, I got the following codes: -C0021-02 code which is Brake Booster - General Signal Failure -C121C-00 Torque Request Signal Denied -C212A-16 System Voltage - CIrcuit Voltage Below Threshold -U0401-00 Implausible Data Received from ECM/PCM "A" -C2101-17 Battery Voltage High - Circuit Voltage Above Threshold. (The battery was overcharged, it's tested at 14V, and now we are trying to run it down.) The car is driving and braking smoothly when the ground is level, I can drive forward and reverse with no (braking) issues. But when I drive up the driveway (10%-20% incline, then levels outs) the BRAKE light comes on the dash and then the pedal gets rock hard and it becomes difficult to brake. This happens when I am going forward or reverse into the driveway. How should I approach these?

This is my girlfriends cars, she slacked on the oil changes for sure. My dad and I did confirm that the timing marks are lined up correctly, there is NOT any damage or etc either, my dad used to work on cars a long time and is doing the grunt work with me. He swears everything is lined up correctly. The vehicle has 95K miles, and sadly the cars warranty ran out at 90K, we tried taking it in multiple times when it was under warranty but they stated if its working/running without a consistent check engine light it can't be covered (multiple places told us this)...as the check engine like would go on and off on occasion. Yes, the plugs are getting wet from gas and we tested the coils for power, ground, but it is NOT getting a signal from the computer to start (according to codes and research we did thats normal).

We ordered the VVT solenoids but will probably install those tomorrow, and yes we will continue to watch youtube videos haha.

We have a low voltage code still even though we replaced the battery, so there is a possible battery sensor/ground issue somewhere. I believe this is giving us the code which is preventing a startup, we are getting power to the coils, but no signal for startup (we were told thats because of the codes).

Previous post: https://www.dodgejourneyforum.com/topic/19766-battery-died-now-it-wont-start/#comment-106151 I replaced the crankshaft/Camshaft sensors, and got the Xtool D6s for the relearn, and it was denied and still no start. So today we decided to Crack open the valve cover and take a look at the timing chain...see pics below. The timing chain is tight and doesnt have any wiggle room, at all.

Is my issue the timing chain?

I ended up getting the XTOOL D6S and it wouldn't clear the codes, or do the relearn (denied it) I ended up opening the valve cover, will post the photos in the next post

Get a better scanner that does relearns.....will order it now. Thank you for letting me know that the relearn can be done while the engine is off and while the car doesn't start, that is very helpful and was gonna be my next question. I'll wait for the scanner to come in and get back to you asap with my results.

UPDATE: crankshaft position sensor - replaced Exhaust camshaft sensor - replaced Status: Crankshaft (No start) Codes still present: P0016 – Crankshaft/Camshaft Correlation (Bank 1 Sensor A) P000B – Exhaust Camshaft Position Slow Response P0562 – System Voltage Low I am now checking for spark, there is no spark in Cylinder 1.

What if I change the CPS and it doesn't start? Whats my next step? What if I erase the codes and it comes back? Im still getting the system violated low code too.

What do I do after the crankshaft position sensor is replaced? I read a few different things online....one said disconnect the negative for 15mins, another said immediately start? If doesnt start erase codes?

Will check them first thing.

So the previous cooling issue was a HUGE pain the ass, I ended up replacing the fan which worked but still had the issue of HIGH not kicking on when needed, so I replaced the radiator fan resistor which seemed to solve that issue. There was also a little bit of sludge in the radiator, which I'm going to assume is from oil shops using different coolant, but I drained it and use MOPAR coolant now and it seems to be running smooth. Sadly I think all these coolant issues started happening at once and made it difficult to pinpoint what exactly was going on. I am planning on replacing the radiator after getting this issue sorted. The car has 95K miles on it, and yes the spark plugs have been replaced. I'll check my log to see when I last did it when I get home but I try to stay on schedule. I just received the crankshaft position sensor and camshaft sensors yesterday. So I will be replacing the crankshaft position sensor this weekend. Any tips and or suggestions is appreciated.

I'll double check it, but is there a way to test it? How do I know if its bad? The car is still getting power every where else.

Thank you very much, I ordered the parts from RockAuto and will replace it. Any idea on why the system low voltage code is still popping up? The new battery was checked prior to installing, and is good. Would that prevent the car from starting as well?
