Code Help Please?
P0410 and P1411. 1999 996. Just got it back for trace/repair of vacuum leak which I was assured was repaired. Drove 50 miles and CEL on again with these codes.

P0410 = Bank 1 secondary air injection Cell = ON
P1411 = Bank 2 secondary air injection Cell = ON
There is a shut off valve that is operated via vacuum with a solenoid involved. If they are looking for a vacuum leak this is where it may be. The SAI system is only used during warm up of car to pump O2 during cold starts and shuts off after loop is open to fresh air. There is also a 48amp fuse and a relay to check for the SAI.

Maybe something is vibrating loose. When they were in there it might of made the actual problemed connection good till vibrations disconnected elecrical or other. What ever it is good luck.
