Nice that the warranty clerk caught that, same thing happened to me with a rental car coverage add on I never asked for. Saved my ass when a rock cracked the windshield.

Have you checked the resistance on the old OEM sensor before you tossed it? I saved mine and tested it side by side with a fake, the real one sat around 300 ohms at idle but the cheap one was all over the place depending on temperature. That little test saved my sanity later when I bought another cheap one for a beater, it worked fine for a year but I only trust it on a truck that won't leave me stranded.

Tethering my phone to my laptop got me through a crowded lounge once.

Six hours of rules means you got six hours of entertainment before the game even started, which is more than most nights give you. Sounds like the real problem was your group lacking the patience to actually enjoy figuring it out.

Man, that exact same thing happened to me with a loose plunger on a fire alarm panel, brutal wake-up call.
