This is why I wrote "Pending Code" -twice.
Good luck with the diagnostics. Awful access ,much sympathy.
Before you dig in, may be worth running the engine longer to see if any other Pending Codes appear. I suggest this because it would be a pity to have to do over.
If you remove the SAI pump, run it on the bench for 5 minutes to see if it makes distressed noises or becomes hot. The internals of these pumps have issues. There is a diy to refurb and lube it.Dismantling the pump part is easy but the motor itself is staked. So if the motor is getting hot ,that may become a failure eventually.
On mine you can run the SAI pump with key on engine off using Durametric. If you try the valves - you can hear them make a muffled click.
