On the 5.7l. Run a extra strap between the pcm and a good ground.if you dont it will melt the system down when it looses ground. Multiple grounds.

That certainly is a mystery ... keep at it Dave, we are cheering for you

Going through similar issues with my 2011. Thanks for videos, I’ll learn to be an electrical guru with you as it will be my next step also.

You onto it Scottrods....looks like some kind of grounding issue that's confusing your ecu. Reground everything?!

The saga continues.

Food for thought during my stint as a lift truck tech ( hate that word ) prefer mechanic for Toyota had a few incidents where codes were set by alternator issues. Weired that code needs high rpms before setting. Possible voltage spikes from alt. Maybe possible voltage test.

Hey Sir. I love the new ground straps, I am going to need to get some for the TRX4. Interesting that you had a cam sensor code at first. Your scan tool should have a cam/crank relearn task. Mopar suggests that any time a component involving the cam or crank gets changed that a relearn should be run. I got a few others thought, but don't want to throw a lot of stuff out at once.

No solution to propose, but a suggestion nonetheless: use AlfaOBD to run your diagnostics. It's a $50 US Android app + a $90 US Bluetooth dongle that plugs into the OBD-2 port. AlfaOBD is Mopar-specific diagnostic software and it's bidirectional. You can run all of the individual component tests on the engine controller as well as the other control modules, which is a great help in diagnosing problems like this. If you don't have an Android phone but you have a Windows laptop, you can use that instead. If you don't have a subscription to AllDataDIY for diagnostic information on the P codes you're getting, that would also be a great help, although here in the US our public libraries offer Chilton or Motor online diagnostics; I imagine it might also be the case up there in the Great White North. Cheers from Metro Detroit where your truck was built. (I have a 2011 Ram 1500 Outdoorsman, looks like it's pretty much the same as yours.)

Damn man I totally feel your pain.

Not sure if you ever got it figured out, but... Are the replacements mopar? second maybe oil pressure sending unit? I believe the crank, cam and presuure unit are all on the same 5v loop, one can take all three down.

Hi, i from belgium.. Where do you connect the earth braid from the cylinder head which goes down to the bottom of the engine?

There’s an actual procedure to tighten the intake down

My sympathy. Electrical gremlins are terrible. It seems like the things you replaced have all been possible causes, but there's still something lurking in the background. One of the things I've learned over the years, if something is driving you crazy and nothing seems to be working, it is often some fundamental, simple thing. I know you've just replaced your earth straps, but that's the kind of thing it usually turns out to be. Or something like that, low voltage, a bad sensor that got replaced with another bad sensor. Who knows. A good meter will allow you to check a lot of that, and much more. Good luck, at this point you need and deserve it.

Fuel cap

Did you try to disconnect the battery and clean the terminals?

Welp i know what im about to go check 😂

Hi guys from Victoria Australia

makes me think injector/s or electrical

can that ground strap make my gas pedal act up if it goes bad

Check with KZfaq Wes at work

It still bothers me that you still buy the cheap Chinese replacement parts. Go to the bone yard and get some used Mopar parts like you did with the BMW. IMO used OEM stuff is far better than stuff from the land of almost fits.

It can't be a TPS issue, sensor, or bad throttle body(needs cleaning)? Camshaft or crankshaft sensor? At which cylinder was that cracked seal?

Ground on computer

Question: did you check your cats had proper flow. Had this issue on my hummer. bad cats

Did you ever figure out what was wrong with it?

Corrosion in the edu connector?
