My name is ***** ***** I will assist you.

That code is for Doser fuel valve not plausible.

Unfortunately, this code wil need DDDL hooked up to the truck to diagnose. The reason is the issue can be a bad valve, bad air to the valve, bad fuel to the valve, or the injector doser. It can;t be determined which without connecting a laptop to it and going through the different doser testing procedures. You will need the DDDL program to activate the air valve, shut it off and check for dribbling, open the valve and see how good it sprays, test the air valve for the proper air pressure, etc. Without this and just replacing parts, you can burn out the dpf filter and very quickly which will cost $5k to repair it in parts alone, not including the labor to replace the filter and all the sensors/harnesses.

I highly suggest getting to a shop or if you are in a shop to connect up the DDDL program and go through the doser troubleshooting tree.

You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see,
touch, smell, hear, or taste the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

The system DOES NOT automatically give me credit from your deposit. A rating is REQUIRED. You are rating me for the information I provide,
not the website. I have no control over the site fees, site errors, category errors, or how long it took for a response for these reasons.

I am not an employee of this website, so please rate with a POSITIVE (green) rating for me to get credit for assisting you. You still pay
the website for negatives or by not rating at all. I just get nothing from that payment you made. So please rate each answer I provide.

I want you pleased with my service to you so please inform me before rating negative (red) and I will do my best to make it right. Follow
ups for same question are always free after ratings have been made.

I do have many workshop manuals, diagrams, etc that I pay to get access to out of my pocket. If one is needed, please ask and I will give
you an offer at my technician discounted cost to you for such manuals. I never charge above that cost.

Thank you for allowing me to assist you through Just Answer!
