Fault codes P0492 and P0581

[tom-4hcey]

Hi my 2013 vantage s has recently come up with the following fault codes when plugged in with my foxwell code reader.

P0492 Secondary air injection system insufficient flow (bank 2)

P0581 Speed control multi-function input A
circuit high

The car has barely been driven over the past year apart from for an MOT and a couple of other trips. I got the emission system service light come on when I last deove it and also noticed when I switched on the cruise control it came on and switched off and said engine system service on the dash. That cleared when I switched then cruise control off.

Any advice would be much appreciated.

Thanks

I’m afraid that all I can offer is the very typical, get your battery checked. Especially if it’s not been driven much.
Hopefully it’s as simple as that.

Anyone had either of these codes?
