steventothemax 0 Report post Posted February 3, 2017 I have what seems like a common issue. Locked in 4LO, Check engine light with P2442 code. (bank 2) Changed to a new secondary air pump. Fan and filter on old one was intact. 50a fuse for Air Pump is fine. With new pump in it still stays in 4LO and Seondary air pump doesn't turn off. Any suggestions?
