Secondary Air Pump system will not complete drive cycle

A "drive cycle" should have no bearing on SAP.

I don't think 01 has MAF for the sap so I'm not even sure how it checks for it working.

I would unplug the SAP to force an error and see what comes of plugging it back in.

It "feels like" a soft failure. Pump runs but it's not really outputting what's needed. No idea why that's not presenting as an error.

Sap only runs on a cold start "drive cycle" doesn't really apply.
