I have a 2008 Tundra d-cab with a 4.7 v8 just got this dang code P2442. My question is this, how do i know what is damaged between the Air pump and the Secondary air injection check valve? i disconnected the hose that goes from the air pump to the check valve, disconnected the battery and i got no codes truck is working fine just idling a little lower. has anybody figured this out? dealer wants to replace air pumps and both secondary air injection check valves. charging me $3200 that i don't have. can anybody give me a hint please?
