Ok.....about a month ago my truck threw DTC P2146 (Fuel Injector Group A Supply Voltage Circuit Open). I was in a parking lot and it ran rough for about 5 seconds and that was it. I cleared the code with my Superchips Flashpaq, which at that time was set on Performance Mode. After running perfect for 1 week, I started the truck early in the morning. It started and idled perfect, but died after about 5 seconds. It did this 3 times before I decided to drive the wifes car for the day. After sitting in the driveway for the day, I got home and it started right up. Idled and ran perfect. I programmed the truck back to STOCk and sold the programmer. Now, for the past couple weeks, when I start the truck in the morning it acts like it wants to die while idleing. It starts great and idles great for about 4-5 seconds, but then begins to die but quickly recovers itself and keeps idleing. It has died a few times, but I do get it restarted. Yesterday it gave a code after dying, P0341 (Camshaft Position Sensor Performance/Rationality). Below is a couple videos of it starting and chokin in the mornings. One thing to note......batteries are original and I have NO issues when starting and driving the truck after work when its warm!! Any ideas?!?! Could it be weak batteries and the truck tries to die when the grid heater cycles?!?

Couldn't tell ya where the cam sensor is, but if that's the only code you had show up, then it's obvious it's a bad sensor, wiring issue, or the ECM.

INJECTOR DTC’S PRESENT

If the batteries were that bad, you would be throwing other codes as well.

 

Sounds like an electric gremlin.. Check this out: https://www.dieseltruckresource.com/...re-t81936.html



Found this very same problem on my truck that was causing the truck to randomly shut down while cruising down the highway. Ended up being a short.

 

None of the pictures are showing up from that original thread. This will reallys show how dumb I am when it comes to this stuff....but where exactly is this wire and where is my AC compressor?!? I do change my own oil, so I know where the oil filter is!!!!

 

Let me see what I can dig up.. The ac compressor is on the passenger side of the engine compartment at the bottom just behind the radiator.

This picture is from the bottom side looking up directly at the oil filter.

 

Oh Ok....WOW....so those little tiny nicks in the wire coating were causing some issues?!!?

 

Especially if they are close to metal or any other means of grounding

Well, I have an appointment to take the truck to the mechanic Monday morning!! I REALLY dont want to do this, but I have no idea where to start!!! Any other ideas or suggestions are greatly appreciated!!!

 

Let us know what he finds.. Hopefully its a quick easy fix

 

Well, checked all my wires and they are all good! I went to Autozone this morning, and had my batteries load tested......turns out both were shot!!! Bought new batteries and I pray this was the culprit!!! Im still taking her in to the mechanic Monday to get checked out....keepin the fingers crossed!!!
