P0410 and OPS
Car was at a stoplight and the oil pressure sensor gage pegged at 80psi (and has stayed there)and simultaneously threw the P0410 Secondary AIR system fault code. Coincidence or is it related? I think it is a coincidence but if somebody else has ever heard of the parts failing at the same time I would like to hear about it.

Unless something got behind the intake and screwed with the OPS wires/connector and goofed up the A.I.R. pluming at the same time, Id say they are NOT related and you just met Murphy! 
Just for the hell of it, attempt to clean the valve using carb cleaner through the hoses for the valves and see if it goes away for a period of time.
The only true fix for that A.I.R DTC is to replace the check valve or eliminate the system.

Not 100% true. I had that code and it wasn't due to a bad valve—the hard vacuum line from the pump to the vacuum manifold under the battery had developed a crack, so it wasn't holding vacuum. Ran a new rubber hose and the code problem was solved.
