On a 2008 Toyota Highlander, Bank 1 Sensor 1 refers to the upstream oxygen sensor located in the exhaust system. Specifically, it is positioned before the catalytic converter on the driver's side of the engine. To access it, you may need to lift the vehicle and remove any necessary components for better visibility. Always ensure the engine is cool and take safety precautions when working on the exhaust system.
its located in the back of the motor.
Bank 2 Knock Sensor under intake manifold block, near the passenger side. Bank 1 is near driver side
The rear cylinders are 1-3-5 so that is bank 1. Front cylinders are 2-4-6 so that is bank 2. Follow the exhaust pipe from bank 2 and you will find the O2 sensor.
bank2 is opposite side of the cylinder 1 and sensor 1 is before catalytic converter so the 1 near the radiator on the top
Assuming this is for the V6, Bank 1 refers to the bank of cylinders toward the back of the engine compartment, near the firewall. Bank 2 is in the front of the engine compartment. Sensor 1 is the top sensor on the exhaust manifold right before the pre-catalytic convertor. Sensor 2 is the sensor after the pre-cat and before the exhaust merge.
On a 2003 Toyota Highlander with a V6 3.0 engine, Bank 2 Sensor 1 refers to the upstream oxygen sensor located on the exhaust manifold on the driver's side. Bank 2 corresponds to the side of the engine that does not contain cylinder 1, which is the passenger side in this configuration. To access it, you may need to remove certain components for better visibility and reach.
replace oxygen sensor on the left bank(side towards front of car) it is located on the exhaust manifold staring you in face when hood is open Read more: Toyota Highlander Limited what does trouble code p1150 on - JustAnswer http://www.justanswer.com/toyota/490ow-toyota-highlander-limited-does-trouble-code-p1150.html#ixzz1T8tewlwW
bank 1 sensor 1 2002 on toyots sienna
That code means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be. It could be a bad oxygen sensor, a bad catalytic converter or and exhaust leak.
Bank 1 sensor 1 is closest to the firewall and located just below the exaust manifold. Easiest to change from under car.
bank one is close to the fire wall sensor one is before the cat
before cat
