Why is my 1391 code not working on my Dodge Ram?
Why is my 1391 code not working on my Dodge Ram?
The same thing applies to your 1391 code. It simply says that the cam and crank sensor don’t agree with each others timing, and the thing between them is the timing set. But again, if your supply voltage isn’t where it should be, you likely have other problems you should address.
Can a crank and cam sensor be replaced?
I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next. My car has 91000 miles. My car has an automatic transmission. You should check to see if your vehicle has jumped timing.
What’s the p1391 code on a Dodge Ram?
Need help with p0340 and p1391 codes on 01 dodge ram 3.9L 6cyl. Have replaced cam sensor (distributor pickup coil) 3 times and crank sensor. Truck runs fine when cold, but after fully warmed up, it surges and jerks and stalls, making odd noises like a misfire (or maybe timing chain sounds) and triggering CEL and p340 and p1391 codes.
How to set a blanket code for a cam sensor?
The cam sensor needs to be within 10 degrees of crank to by in-sync, otherwise the cam signal isn’t recognized by the PCM. The fleeting nature of a cam sensor sitting right on the fence between in and out of sync would be tough for the PCM to figure out, so it sets a blanket code (P1391).

Is the cranksahft position sensor on a Dodge Ram a problem?
The cranksahft position sensor (CKPS) on the second generation Dodge Ram can be a source of problems as your truck gets older. If your ECU is throwing CKPS codes, it’s time to pull out the tools and change it out for a new one.
