CEL - P1411 Secondary Air Injection System

I got a CEL this morning and my OBD is telling me it's a P1411 - the Bentley Manual gives two possible causes...

- Signal implausible/ implausible operating range / malfunction
- Short to Ground / below lower limit / lean mixture threshold

Can someone shed a little more light on this?

One thing to note, and I'm not sure if it means anything but this morning it was raining, the first time in several weeks. Also I just recently replace my MAF, not sure if that's related.
