Leveling kit

Hey guy, my truck started acting up after I used 4 wd hi and put it back in 2 wd. The 4wd hi started flashing and I found a broken vacuum line. Now it still flashes and my ck engine light, antiskid and 4 wd low all came on at the same time and the truck went into limp mode. Code read is p-2440 which is secondary air pump which is emissions and shouldn't put it in limp mode. I bought this truck new in 08 and never had a problem until now. I've got 166,000 miles on it now. Any ideas?

take it to a parts shop to plug into their scan tool. Almost sounds like SAIS emissions BS.
