The O2 sensor Bank 1 Sensor 2 on a Toyota Sienna is located after the catalytic converter on the driver's side of the vehicle. It is typically found along the exhaust system, near the rear of the engine. This sensor monitors the oxygen levels in the exhaust gases, helping to optimize fuel efficiency and emissions. Accessing it may require lifting the vehicle for better clearance.
On a Toyota Sienna, Bank 1 Sensor 2 is located on the exhaust system, specifically after the catalytic converter on the driver's side. This sensor monitors the exhaust gases to help manage emissions and fuel efficiency. To access it, you may need to lift the vehicle and possibly remove some underbody shields for better visibility and reach. Always consult the vehicle's service manual for precise locations and instructions.
its not a sensor you timing belt jumped a tooth on the camshaft sprocket on the rear of the motor...the Bank 1 camshaft...which is the one that sucks to get to
