In a Toyota Tundra, the bank 2 sensor 2 is located just after the catalytic converter on the side with cylinder #2. It's responsible for measuring oxygen levels in the exhaust gases coming out of the engine. Experts recommend changing this oxygen sensor every 60,000 to 90,000 miles since it can wear out over time. A failing oxygen sensor can mess up the fuel delivery and combustion systems, affecting your vehicle's gas mileage. If there's a problem with the sensor, it can disrupt the air-fuel mixture, causing too much fuel to be injected into the engine and reducing your gas mileage.
Um, alright, but can you tell me which side cylinder 2 is on?
