Received an engine error on the dash. Using an OBD tool, it was showing the knock sensors 1 & 2 were an issue. Had to get vehicle towed to dealer. Dealer determined that a rodent chew had occurred. It is obvious from the pictures they were being honest.

Now, I know about the soy wiring harness stuff. And the interesting part of this is that if you look at the wiring harness, the parts that were fully enclosed did not suffer any chewing. It's the part of the harness that the wires were not fully encased as they entered the connector that were all chewed up. No nest or nesting material was found, it was clearly a chew incident, but it was something done and they left.

Seems a shame to leave exposed wires, not only because of issues like this, but also it allows the elements to penetrate the connector and over time will provide corrosion on the connector internal metal, the copper of the wire where it meets the connector, etc. It would take some simple shrink tubing around that part too, to help assist or eliminate rodent chews, but also slow down the mechanical break down of the connector/wiring within the connector.
