2017 Sierra 5.3 4x4 crew cab short bed. So I had a Rhino liner sprayed in my truck yesterday, and when I picked up the truck the CEL was on for the first time since I’ve owned it. It was pouring rain and I was in a hurry to get back to work, so I figured I’d deal with it later, and maybe they unplugged something or let the battery drain. Light stayed on back to work and again on the way home. Checked the codes and it had a p0449 and another one for throttle position, but drove fine. Reset the codes and drove to work today with no CEL. Remote start wouldn’t work when I left work, and sure enough it was back, but just the p0449 this time. I checked all of the hoses, wiring, and what I could see of the tank and etc but I see no problems. The solenoid is under the cab and not near the bed, so any ideas if they could have jacked something up when prepping or spraying? Truck is under warranty but I don’t want to pay $100 for GM to say that Rhino folks messed something up and it’s not covered under warranty, but don’t want to harass the bedliner guys if it truly was a coincidence and not related to anything they did. Thoughts?
