Fuel trim bank 1 refers to the adjustment of fuel delivery for the engine's bank 1, which is typically the side of the engine containing cylinder number one. This adjustment is made by the engine's electronic control unit (ECU) to optimize air-fuel mixture based on feedback from the oxygen sensors. Proper fuel trim settings are essential for engine efficiency, performance, and emissions control. Issues with fuel trim can indicate problems in the fuel system, air intake, or exhaust systems.
