I have a 2010 Tundra 4.6L V-8 with Code P2445 which is the Secondary Air Injection Pump Bank1. These airpumps are notorious for going bad and the engine goes into limp mode which restricts power to 50%. Before replacing the pump or bypassing it with a kit I want to check the relay just to be sure a bad relay isn't causing the pump not to work.
Unfortunately, I can't figure out here the relays for the pumps are. They are numbers 45 and 46 according to the cover and what I found online but the location on the actual underhood fuse panel is blank. Are they hidden under a panel and, if so, how do I access them?
