I’d attach a pic for you all to make fun of me but hey at least I’m trying to learn the ways of the wrench turning truck driver! I picked up the back pressure sensor but didn’t have the 27mm socket with me so I’ll get it in the morning. Wish me luck!

Be sure to spray a bit of brake cleaner in the sensor hole while the sensor is off of it and crank the truck, let it fire up for a moment to ensure it blows the brake cleaner back up out of the hole ... that circuit for the exhaust pressure sensor likes to get blocked up with carbon buildup.
