2006 Toyota Tundra SR5 4.7L MIL Lamp on
Posted to Asian Driveability on 11/5/2018 11 Replies

I have a 4.7 tundra with rich codes. Smoked the system and no leaks. Both up stream sensors are at 3.25 volt and will change with load. The rear 02 sensors are at .85 and stay there. If i create a vacuum leak the fronts will go to 4.2 then come back to 3.2...
