Hi I have a p0394 so I replaced both can sensors just cuz it has 100 thous miles and it still comes back. Thing is that it comes on in exactly the same mileage or time every damn time? So it's not intermittent or it would come on sooner or later Everytime not exact same time? Any ideas appreciated?

15 dodge ram 3.6 code p094

- Start date
I have checked every in or harness and connectors, I have checked pins, and if it was wireing you'd think a wiggle test would cause code and it don't and there's no way it would happen at exactly the same time or mileage Everytime? It would vary in how long it took to come on I'd think?
How many times has it repeated setting the code? How many miles and minutes does that require? Are each of these settings of the code after a single key-on and engine start cycle? Have you disconnected every connector, inspected contacts, and re-connected? Wiggling wires is not a definitive test.
It has repeated 7 times now, it takes right at 8 miles at 60-65 mph,yes single key on start,I have disconnected most, not all, I havnt dun sum of the big connectors, but most small ones,and cleaned out dielectric grease and reconnected,ya I know it's not definative but you'd think since my scanner has a wiggle test on it where u wiggle the harness it would eventually make something diff happen? Like longer or shorter time til code set?

That is about a mile/ min.
What if you just let it set and idle or run at some other rpm for 8 - 10 min, or even at the same rpm as it would be at 60-65 mph, (2000 or whatever) will it code?
And what if you go 8 miles at another mph, (like 30 or 40) will it code?
Not sure what that tells us, but it may help us diagnose.
BTW, what is the code-- you listed 2 different ones in your post.
Let's try again...
P094 is not a valid P-code number, there must be a "P" and four more characters. I think we are all assuming it is P0394, but please confirm; and take more care in avoiding typos. Typos will tend to cripple our efforts to help you; they give us bogus info to work from.

I am having this same issue in my 2016 Jeep Wrangler. Only comes on at the same time. I have replaced both sensors had a wiring overlay done changes out many other things and about to pull my hair out did you ever get an answer to why yours was doing this?

I know the early days when jeep and dodge got together the aftermarket sensor didn't make the same signal so even new sensors would not fix the issue.
Also when you installed new sensors did you set them correctly?
There is a lot of information on this topic.
P0394 Camshaft Position Sensor Intermittent - Bank 2 Sensor 2 - This diagnostic runs continuously when the following conditions are met, Battery voltage is above approximately 11.0 volts, with the engine running. Set conditions, with the engine running, the Powertrain Control Module (PCM) acquires and locks in on a pattern for the camshaft position (CMP) sensor signal. If the CMP sensor signal pattern changes between unlock and lock at least four times during a period of eight crankshaft revolutions, a fault is set.
Possible causes P0394 code
