bank 1 sensor 1 2002 on toyots sienna
its is located downstream on the backside exhaust manifold
Bank 2 sensor 1 is the O2 sensor in the exhaust manifold closest to the firewall.Cut and paste the link below for a detailed fix with pics of the O2 sensor repair."http://polifrogblog.blogspot.com/2009/11/sienna-o2-sensor-change.html"
Bank 2 is the sensor opposite from the number one cylinder, and on your vehicle is the front of the engine. Sensor 1 is the first oxygen sensor you come to from the engine in the exhaust pipe.
Bank 2 is the side of the engine that faces the front of the vehicle, sensor 1 is the upper sensor, it is in the exhaust manifold
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.

its located in the back of the motor.
Trouble code P0150 means:O2 sensor circuit malfunction (Bank 2 Sensor 1)
The Toyota Sienna code P0156 indicates a problem with the O2 sensor circuit, specifically for the bank 2 sensor 2. This sensor is located after the catalytic converter and monitors the efficiency of the exhaust system. A triggered code can suggest a malfunctioning oxygen sensor, wiring issues, or exhaust leaks. It's important to diagnose the exact cause to ensure proper vehicle performance and emissions compliance.
Trouble code P0153 means:O2 sensor circuit slow response (Bank 2 Sensor 1)
Trouble code P0153 means:O2 sensor circuit slow response (Bank 2 Sensor 1)
Bank 1 oxygen sensor is the closest to the engine exhaust manifold. It is usually can seen and replaced if necessary with open hood.
