| Engine code trouble
So I got the SES light yesterday and decided to check it out. I stopped at Advance Auto and they did their free check. the codes that came up were
P0492 secondary air system bank 1
P0491 bank2
Any help on what could cause those? The dealer said those codes meant nothing to them and I would have to use their diagnostics which takes them an hour.
Also, it's been really cold here lately. Snowin all day today. I heard that might cause the problem.
