Some of the vehicle information you will need includes:

ALWAYS COMPARE THE DIAGRAM DETAILS WE PROVIDE ON THIS WEBSITE before purchase to ensure the Connector Plug and Cable Length comply with the sensor you are replacing.
You will also need to identify if the sensor you require is BEFORE the exhaust system CATALITIC CONVERTER (PRE CAT) or AFTER the CATALITIC CONVERTER or Downstream (POST CAT). More information on the location and types of Oxygen Sensors can be found on the O2 Sensor Identification & Locations page

VIN Number (Vehicle Identification Number)
In some cases you may also need your vehicle VIN number (Vehicle Identification Number or sometimes referred as Chassis or Frame Number on older vehicles). Some models have different Oxygen Sensors depending on the VIN number.
VIN Numbers are made up of 17 characters stamped on the vehicle chassis or ID plate. To avoid confusion these characters never have the letter ‘O’ or ‘I’ they are always numbers zero or one.
This VIN number is unique to your specific vehicle and can be used to identify the correct sensor required,the same may apply for the need to find the vehicle Engine Number. Usually you can find the VIN stamped on a metal identification plate attached to the vehicle.
The diagram below highlights some places these ID plates, or Compliance Plates, may be attached to the vehicle.

The engine ID number will often be located on the lower left of the engine block (stamped on the rear end raised area of the Cylinder Block left side), however it can be located in one of several positions.
