Kindly reminder:
Finding Your Oxygen Sensor's OEM Part Number
Please try to confirm the exact sensor (such as part number, sensor position) for your own car before placing the order.
If for any reason you cannot find your oxygen sensor by entering your vehicle's year, make and model, you can find it by its Original Equipment Manufacturer (OEM) number. The OEM part number can be found directly on the part itself. You can also call a dealership with your VIN, and they will provide you with the OEM part number.

INSTRUCTIONS RELATED TO O2 Oxygen SENSOR
1. Oxygen sensor is located on the exhaust line.
Oxygen sensors located before the catalytic converter are known as upstream sensors(FRONT), while oxygen sensors located after the catalytic converter are called downstream sensors(REAR). Upstream sensors are usually more sophisticated because their role is to report to the ECU the oxygen concentration. Conversely, the downstream sensors main function is in helping the ECU to determine the catalytic condition.
2.Knowing the location of the oxygen sensor at fault is important.
The number and location of the oxygen sensors are specific to every vehicle's year, make and model. The location of the oxygen sensor is usually identified by position (sensor 1, sensor 2) and by cylinder bank (bank 1, bank 2).
Bank 1 is the side of the engine where cylinder #1 is located.
Bank 2 is opposite to Bank 1.
Sensor 1 is the upstream sensor.
Sensor 2 is the downstream sensor.
In case of a four-cylinder engine, there is only one bank: bank 1.
FOR EXAMPLE:
3.How many oxygen sensors does my vehicle have?
This depends on your automobile's year, make and model. Older automobiles had a minimum of two sensors whereas newer automobiles can have six, eight or more oxygen sensors.
4.How do I know if my upstream or downstream oxygen sensor is bad?
There are several signs that you might notice when your o2 sensor malfunctions:
Reduced gas mileage
Reduction in overall power
A gas smell coming from the exhaust
Check Engine Light
Rough idle
Misfire
Hesitation when trying to accelerate
Emission test fails
