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.

On my 5.7l. 2004 ram 1500. The single bolt on the bottom corroded badly and caused unstable voltage within the pcm. The top 2 bolts goes into a noncunductive panel. It has burned the transmission control module out and then 3,4, and 5th gear out in less than the 5 miles to get back to the trail head. Completely fubar-ing the transmission and transfer case. I had to run low range to get it to move and ifs constant snatching into gear broke the sun gear and chain. Everything now has extra grounds. When the trans and case get replaced I have 5 ground straps to install. Eng to firewall, eng to trans, trans to t case, trans to crossmember, t case to crossmember, crossmember to frame. Not to mention 3 ground straps to the battery from the pcm, and a spare to the body and frame.

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.

That is a great suggestion cam/crankshaft relearn must be performed whenever major engine work is performed. I had to do this myself when I replaced my camshaft and lifters.

@@marionoliver6004 I had both heads off two years ago to replace some valves. I never did a relearn, and it ran great for the last two years. I'll still try it though.
@marionoliver6004 Жыл бұрын
@@ScottRods yeah I think it’s worth a try. Tolerances were affected when you did the head/valve/timing chain work. If I remember correctly you put a new timing chain which can in theory effect the correlation of both the cam and crank. Also cam/ crank relearn must be performed when replacing the crank position sensor or cam position sensor. Just a thought

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.)

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.

Possibly easier said than done. These DS/DT trucks are still valuable enough at 13 years old that they're not turning up in the self-service junkyards here, which means the cost of the used parts is higher since you're paying someone to take them off for you.
