Error code P0341 Camshaft position sensor ’A’ circuit range bank1 or single sensor

[Hootbro]

Finished up this evening. Ended up using 1/4, 3/8 and 1 inch diameter heat shielding to do the wiring harnesses shown.

also wrapped the wiring with high temp fabric tape first since there where several areas of exposed wiring under the plastic cover. Was a tight fit to get the plastic cap back on but went together pretty smooth.

the cam sensor wiring are some of the smallest gauge wires in the harness and the insulation isn’t very durable on these so I could see them possibly rubbing through on tight corners mixed with the heat and vibration?
I checked all the wiring in the areas Im working on and didn’t see any signs of chafing but again can see why the service bulletin says to replace with larger gauge wire and to reroute it.

Again to clarify I didn’t have any check engine lights for the cam sensor. I just wanted to be proactive on the wiring and try to prevent mine from getting the issue.

Looks good!

I’ve has this code twice. Both times were after a 10min drive, backed In to (the same) parking spot and ran in to the post office. Both times, I came out, hopped in the truck, pulled out out and cranked the steering wheel to the right….pop, code hits. I’m changing the way I pull away from that parking spot to see if the code comes back. Either way, I’m not really worried about it.

Communications network wiring - no current to speak of. Can be really really thin wires.
However - that also makes them vulnerable.
Good job protecting them.
Loss of communication across the LIN or CANbus networks can cause things to freak out.

So - has anyone here had the P0341 code with no drivability issues (ie, code & MIL, and no limp mode), and had the TSB repair, and not had any further issues with the P0341 code? I haven't gotten around to getting to the dealership, figured I'd see what people's results are....

I am 18 months and about 8000 miles into my repair and have had no issues. Fingers crossed! Mine was the one that had one of the prototype shielded harnesses on it (see April 2024 post). But I still have no idea what that is, sorry I can’t be more helpful.

Well looks like I'm in the club now, 2023 with 29k on it. I guess I'll see what the dealer does, is there a consensus that the "fix" the engineers came up with works? I hope I don't have to jump through too many hoops to get my dealer to proceed with fix.
I've had no operational problems (power loss) that I can tell, the first time it was after it was full hot and shut down briefly, engine light reset itself, then yesterday it did it on a cold start. The problem with a factory warranty is you have to go to the dealer....

Heating of wires can change the resistance of the wire and depending on what they are doing would make sense as the problem, repeated heating could make the damage permanent. It's like burning the windings in an electric motor. I thought having the problem after a brief shutdown of a hot engine made sense (radiated heat when there is no airflow from operation), but now mine did it on a cold start so....

It has been covered before whiring just needs shielded from heat. And FYI
The gas ones have the camshaft sensors go clear out . Mine did . But the diesels are experiencing this in early mileage and several ha e figured it out . Its one of 2 things either twisted up wiring or unshielded wiring sitting too close to the egr heater area. Once the wiring to the sensor is compromised then it doesn't send signal then you end up in limp mode . Limp node occurs because of lack of input. Then the computer doesn't know how to mix the fuel etc. The very same thing occurs in the gas motors . This is a very o early simplified explanation so dont hammer me on it. But I have owned 2 Ram diesels previously so I am quasi familiar with diesels.

Has anyone heard if there is a similar problem on the Wrangler diesels?...

IF it is a diesel the heat may get to it .. go to the JL Wrangler forum its a sister forum to this one probably info there on this issue.

The resistance returns to normal once cooled. Repeated heating and cooling within the wires design limitations does not permanently increase resistance. (burn insulation, yeah)
Heating and cooling can result in other things - but the resistance returns once cooled unless taken to the point of annealing and so on.

Burning windings in a motor is a totally different animal - that's extreme heat beyond what the wire itself - the metal wire - can handle.

Insulation damage is what happens in extreme heat like that - the lacquer is burned off, or the wire is literally taken to the point of being orange, destroying the molecular structure, making it hard, brittle, and breaking.
Vibrations and extreme heat can cause the wire to get brittle, work harden, and break. The insulation will often break down first before heat ruins the wire itself.

These won't "radiate" enough heat to cause the wire to gain any resistance to the point of any trouble or voltage drop.
You should see the extremes I run into in restorations, wiper and blower motor repair and so on.
I've probably seen about any sort of wire damage that can happen.

Update: As he didn't have the TSB, they didn't do EVERYTHING that they were supposed to. Part on order for almost 4 weeks now.

Bobholthaus- thanks for your pursuit and information on this potential fix. I have been following the Gladiator and Wrangler forums where you have been commenting. I also have this same issue among other issues and am curious to know if you have any more information on the fix. I think your last comment was there was a part on order early July. Have they installed it yet? I would ask you in the Wrangler forum but am waiting for approval from an administrator to comment on that forum.

So the dealer did my final "fix" about a week ago; they had claimed that there was one more thing to do to "complete the TSB". And then the light went on about 3 days later. I am going to try another dealership next, and then I am going to open another case with Jeep.

Took mine in yesterday, they have given me little information so far other than "parts are ordered and supposed to be in today", the advisor is going to give me a call this morning with more information. I'm just hoping I get it back today, the "to die for" Compass I have as a loaner isn't likely going pull my trailer to the job site. Not sure if it will really be fixed from what I've seen on these posts but at least I'll be in their system as a known problem should something happen in the future. I'll just clear the code from here on out and let them know.....

Got mine back after 3 days, they did the "fix" of re-routing the wires and shielding, but they found something I haven't heard mentioned here. There were loose pins on the cam sensor wiring harness connectors (three pin connector).
That would actually better explain the problem than "electro magnetic" or "heat" because it would seem those problems would be a constant rather than intermittent if they appeared at all. Loose pins on the other hand could be quite variable and come and go depending on driving condition vibrations or even be constant. And with these parts suppliers if they shipped one defective part, they shipped a thousand or more.
Keeping my fingers crossed the loose pins were actually the problem.

And with these parts suppliers if they shipped one defective part, they shipped a thousand or more.

And having personally worked in electronic manufacturing - it can be 1 in 100,000. A fluke, a miss out of thousands.
There's absolutely a such thing as a "one-off".

And then there's this example - real, not internet rumor, from a company that made electric and electronic components for auto makers, including Toyota.
There was a special relay being made - a new guy in QA was trained - 10 iterations of the test, if it fails, it's done.
So he goes on to testing those 10 iterations of each part - if it failed, he kept testing until it succeeded passing the test, and called it good.
Toyota started having an abnormal number of warranty claims and followed the path to the company in Illinois and visited the company in person. When it was seen what that guy was doing..........
He thought his goal was to see if it would pass, and if he could make it pass, it was ok, but the real goal was "see if it will fail, and if it fails, it's done.

One might slip by
or
there's a flaw either in automated assembly (one reason to trace LOTS, times made, and so on) or someone is messing up a process.
And in the case of one Chines company, it was traced to the women doing electronic assembly work - because of body chemistry changes certain times of month - there were periodic surges in failures, and then back to ok, then xx days later, another surge in failures..............
The solution was - everyone wears gloves, especially certain times. It slowed things a bit, but got rid of the periodic failures.
