In this video I show you how to switch out the Secondary Air Injection Valve on bank 1. This is a 2008 4.7 tundra. The valves tend to get stuck due to water getting in them. This is now the 3rd time I've had to switch out a aip valve.
Temp Fix: (I'm not responsible if you break your truck)
If you can't wait to fix this issue, and need to get your truck out of limp mode. Reset your ecu to get rid of the cel, and the truck will work fine until you can swap the valve out.
