2018 MDS Issue

Just bought a power wagon 2 weeks ago and the CEL is on. It’s throwing codes P3402, 3426, 3442, 3450. The truck has 1100 miles on it and I’m currently on vacation. The truck drives fine and seems ok. I put new gas in it and some Lucas fuel cleaner in it. Have you guys had any experience with these codes and what’s a good course of action to take. I’ll be taking it to the dealer once I get back home.

Light went out this evening. Must have not liked the gas that I put in it last night. Weird.

take it to the dealer.
let them check and clear codes.
run the Lucas fuel cleaner for a few tanks.
Run 93 for a full tank, and you can dilute the current tank with 93 as well.


pretty much the same thing happened to me a few weeks back, and it was the first time i filled up at this crap station in 20k miles.

Took that course of action above, and it hasnt happened since.
