What do these codes mean? Should I be concerned?

Hey everyone. This is a continuation of my other thread:

V6 engine light on while towing?

Basically the dealer flashed my PCM after finding these two codes:

First
PCM P000D Bank 2 Camshaft 2 position slow response.

Second
ACC C1266-00 ACC sensor blinded

I'm quite concerned about this as the dealership didn't really explain what these meant and I'm ready to pull the trigger on a new travel trailer. I was test towing the trailer when my engine light came on.

Thoughts please.

1. Cam position sensor - They should have checked or replaced this sensor, PCM flash may fix it. Like they said wait and see if it comes back.

2. Adaptive Cruise Control eye got blinded - something was obstructing it's "view"

All in all I'd say the same as they did...drive it and see if the codes come back.

Re: What do these codes mean? Should I be concerned?

Ok sounds good. I just happened to be down at the shop again and was speaking with a tech. I told him I'd read about a few 3.6's blowing the 2nd cylinder. He said well that camshaft 2 code is related to that and maybe I should bring the jeep back in the morning and speak to the foreman to get it looked at more closely. I agreed. Does this sound like a real fear to have?

I'd have it looked at more closely. It's worth the piece of mind you know.

Well I spoke to the shop foreman and he said he wouldn't be concerned. He didn't recommend I pull a trailer weighing 4300 lbs because it would wear on the Jeep. This confuses me. Jeep gives these vehicles ratings but your not supposed to use them for fear of breaking them?

You are close to limits (especially if you want to carry passengers) but I can't see how that would be a problem either.

Re: What do these codes mean? Should I be concerned?

The 2012 GC Laredo X 4x4 with the 3.6L is rated at:

5,000 lb towing (with factory tow package)

AND

1,240 payload inside the vehicle

The Limited and Overland are 90 lbs less payload due to their option package's weight. It's in your owner's manual.

As a former owner of several light-weight and full size pull-behind trailers, 4,300 lbs may be pushing the capability of the V6. 4,300 lbs is probably factory rated dry weight. By the time you add accessories (jacks, antenna, spare tire, etc), options (AC, TV, bedding, 2nd battery, etc), LP/fresh/grey/black water tanks full and fill the storage compartments on that trailer - you may surpass 5,000 lbs.




Jayco X213 Feather Weights
  • Unloaded vehicle weight (lbs.): 4295
  • Hitch weight (lbs.): 475
  • Gross vehicle weight (lbs.): 5500
  • Cargo carrying capacity (lbs.): 1205
The large frontal area of that trailer will be a big drag on the V6, even with the streamling and even if you are able to keep it under the 5,000 lbs. I would never consider to tow that trailer with the V6.
Personally, I would look around for a lighter trailer. There are many other "light-weight" low-profile trailers and extendable (high-low, etc) trailers out there. Best luck.

Based on those numbers I'd agree that the camper is too heavy. One other thing to keep in mind is that the V6 has a limited frontal area (don't remember the number but it's in the owner's manual).

That said, if the camper had a gross vehicle weight of 4300 lb you would be close but OK. Still don't know how towing a camper would cause a CEL.

Re: What do these codes mean? Should I be concerned?

Thanks for the info. I worked out what we take with us when camping. All in all I would be 600-700 under my absolute gross vehicle weight and towing weight so I've decided on a Jayco X19H which is 700 lbs lighter than the X213. Now even after being fully packed and ready to go I'll still be under the dry weight of the X213.

On another note while I was driving home a few minutes ago the engine (MIL) light chimed and came back on...phoned the dealer and made another appointment for the AM. The light is not flashing and the Jeep is driving fine as was the case on Saturday when it did this for the first time. I'll post what I learn tomorrow.

Re: What do these codes mean? Should I be concerned?

That is a lot of weight for the V6. I tow a cattle trailer in my V8 1/2 ton truck with 4.10 gears (yes I'm a country boy) that weighs around 5,000 pounds loaded and it is working to pull up hills so I can imagine how the much it works the V6 with a 3.06 gear ratio. The hemi's gear ratio is not much better but atleast it has the displacement to get the job done. Jeep should offer a better selection of gear ratio options for people who intend to do alot of towing but I guess that would hurt profits.

Re: What do these codes mean? Should I be concerned?

Well I just got back from the dealer. They said the "Cam phaser" needed to be replaced and they had to order the part. Does anyone know whether this is a big deal or not and whether test towing that heavier trailer would have hand something to do with it?

Re: What do these codes mean? Should I be concerned?

Your cam phaser is part of the VVT (variable valve timing). It operates all the time as you drive the Jeep. It advances and retards the camshaft depending on your RPMs to give you the most power possible at any given RPM value.

Towing has nothing to do with it. Bad part from the get go.
