One of those mysteries! I had a similar thing happen with our Jeep. Got a check engine light and codes said Intake Air temp sensor and knock sensor. Popped hood and found dipstick pulled half way out, wires severed for both sensors that are not that close to each other? The knock sensor wire looks like it was cut by wire cutter but the other wire was more smashed like? Only thing I can figure is a critter (Cat) got in there for the warmth and when it was started up it panicked and thrashed around and did the damage?
There are bold motorcyclists and old motorcyclists, but (OK) there are few old bold motorcyclists
