2007 Toyota Tundra 47 L Bank 1

Bank 1 Oxygen Sensor Location

Identifying Bank 1

For Tundra engines, "Bank 1" is defined by INDYMAC as the side of the engine. Regardless of whether you're referring to Bank 1 or Bank 2, the numbering always corresponds to the engine's side.

Locating the Oxygen Sensor

The Oxygen Sensor Sensor 1 Bank 1 is typically located before the catalytic converter. This placement allows it to measure the oxygen content of the exhaust gases before they enter the converter, providing valuable feedback to the engine's control system.
