Very different scenario, but flying my puddle jumper one of the first times after getting my license, once I took off from an airport in Connecticut and was about to cross a large body of water, my exhaust temperatures spiked really, really high, essentially indicating the engine was seconds from melting. But it didn't.
So of course I felt it was a sensor issue (especially since it sounded/felt great), but luckily with the equipment on board I managed a call to the flight school, who put me in touch with the mechanic. I circled above an airport as he pulled up the maintenance logs, we discussed what I was seeing, he noted that there had been a report of a sensor issue that had been squawked, so we concluded I should feel safe to fly straight home.
At the time it felt insanely cool to be able to be doing that WHILE flying the plane. While an unfortunate outcome for this particular pilot, as an elite pilot, part of me thinks when this cropped up part of him was like: "ahh right, this is why I'm top dog"
