Is O2 sensor bank 1 sensor 1 upstream or downstream?

Is O2 sensor bank 1 sensor 1 upstream or downstream?

Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.

Is O2 sensor bank 2 sensor 1 upstream or downstream?

It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor. It is always going to be located after the catalytic converter.

Can I use the same O2 sensor for upstream and downstream?

A: Each vehicle is different in the amount of O2 sensors they have. A: The upstream sensor threads into the pipe coming from the engine, closer to the front of the car, and the downstream sensor threads into the catalytic converter, more toward the rear of the vehicle. They are not interchangeable.

Which O2 sensor goes bad first upstream or downstream?

The main o2 sensors go bad first from the crap that flows & burns through them (Gas).

Is bank 1 driver or passenger side?

No, bank 1 refers to the engine bank with number 1 cylinder. On a small block chevy, this is the driver side. Bank 2 refers to the bank opposite of cylinder 1’s bank. On a small block chevy, this would be the passenger side.

Are bank 1 and bank 2 sensors the same?

Bank One is always the bank where cylinder number one is located. Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine. Bank Two is post catalytic converter.

How do I know if it’s my upstream or downstream O2 sensor?

The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The location of the oxygen sensor is usually identified by position (sensor 1, sensor 2) and by cylinder bank (bank 1, bank 2).

Is Bank 1 driver or passenger side?

Where is the upstream O2 sensor?

The upstream oxygen sensor is located before the catalytic converter. This measures the level of pollutants coming directly from the engine. It also senses any raw, unburned fuel coming from the combustion chambers.

Are bank 1 and bank 2 O2 sensors the same?

Bank One is always the bank where cylinder number one is located. On the Corvette it will always be the driver side. Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine.

How do I know if I need an upstream or downstream oxygen sensor?
