Default P1412 How Bad is it Please Help......

I researched this error P1412... What can i look at to get this corrected? please help.

P1412 = Secondary Air Injection System Malfunction (Bank 1)
This is from the EOBD section of the manual.
From the SAI section:
If the vacuum operated SAI control valves malfunction, the following fault codes may be stored in
the ECM diagnostic memory, which can be retrieved using ’Testbook’:
P1412 is one of these, particulary described as : SAI system fault (LH side) - air delivery not reaching catalysts.
(DS note. The Left Hand side is as viewed from the drivers seat, not from the front of the enngine bay looking backwards!).
The above system faults could be attributable to anything which might prevent air delivery to the exhaust manifolds (e.g. disconnected or blocked SAI delivery pipe, disconnected or blocked vacuum pipe etc.)

The car runs fine, it must have been a really cold start for this to come up.
