Can anyone tell the location of each o2 sensor location such as bank 1 sensor 1, bank 1 sensor 2, and so on for 1999 Toyota Camry V6 Sedan? Thank you.

 

The engine has 2 cylinder banks. The bank closest to the firewall is Bank 1 and the bank closet to the radiator is Bank 2. Each cylinder head has an exhaust pipe with an emissions converter and plus sensor prior to this converter (deemed Sensors 1). The two exhaust pipes join into one then attach to another emissions converter which has a sensor after the converter (deemed Sensor 2).

Bank 1 Sensor 1 is the first sensor on the exhaust system coming from Bank 1.

Bank 2 Sensor 1 is the first sensor on the exhaust system coming from Bank 2.

Bank 1 Sensor 2 is the sensor after the converter on the combined exhaust pipe.

 

Thank you very much for your very helpful information.

 

Hi Joey,

I am still unable to locate this "Bank 1 Sensor 1 is the first sensor on the exhaust system coming from Bank 1" for my 1999 Toyota Camry V6 car. Is it more to the Driver side or the Passenger side? Is it easier to look from the Top or from the Bottom of the car? Would you mind taking a photo with an arrow pointing to this "Bank 1 Sensor 1" please?

Bank 1 is the cylinder bank closest to the firewall. Sensor 1 is the first senor on the exhaust system coming from the head. It is before the first converter on that exhaust system.

Find the converter nearest the the exhaust manifold on the rear cylinder bank. The sensor is located prior to this converter.

 

Maybe I'm blind but can you tell me which of the 4 photos is this "Find the converter nearest the the exhaust manifold on the rear cylinder bank. The sensor is located prior to this converter." Would you mind marking with an arrow pointing to this "Bank 1 Sensor 1" please?
