Yeah I'm wondering if it was a "wrong side of the bed" thing myself... it's extremely weird that's for sure.
As said when the light came on and flashed I turned the car off... then restarted, the light did not come back on and no codes were returned with the key check.
I just went out to the parking lot and started it and let it idle for 3 mins... was at the normal 750ish RPM's and all appears well.
The only thing I can think of was maybe it's water related? It rained extremely hard here yesterday and last night... although I drove it home fine yesterday and while it did get rained on all last evening the hood was obviously down
Will update the thread if it happens again...
