I was driving in the mountains the other day ( went snow-shoeing with my 10yr old ). On our way home I drove over some object on the road, which I never saw, but heard a loud BANG under the truck, looked in the rear view mirror and saw what I assume was a rock spinning back up the highway behind me. Being in the mountains, it was most likely a rock, but I didn't stop and back up to investigate. I can only assume the front wheel must have hit the edge of it just right and caused it to flip up and hit the underneath of the vehicle. I said to myself " well at least I have skid plates, hopefully they took the blow", and drove on.
Stopped an hour or more later at a gas station, and on re-starting the vehicle I had the CEL illuminated. Truck seemed OK and nothing looked wrong on any of the gauges ( temps, pressures etc ), so I drove on home another hour and half or so.
At home I checked the code and this is what I had :
P048D Exhaust Pressure Control Valve Position Sensor / Switch Circuit Low
Guessed it must be something to do with the rock I hit so crawled under the truck on the passenger side where I knew the exhaust is and immediately saw what I'm sharing in the attached picture.
That connector is mounted on the side of the frame, and does have a metal bracket that it sits into. You can't see the bracket in the picture, it's behind the connector. It is however bent out of shape.
You can see in the lower right of the picture a scuff mark where the rock hit the frame.
of all the places it could have hit, it had to hit right there and bash up that connector !
It seems a pretty safe bet that the code I'm seeing is related to this connector being bashed up.
The truck is currently at the dealership and I'm waiting to hear back from them on what to do about it. Somewhat worried they're going to want to replace a whole section of harness rather than just replace the connector.
