Each Range Rover and Freelander requires four (4) oxygen sensors. Two of these sensors are mounted in front of the Rover’s catalytic converter and two behind it. The front O2 sensor – also known as the pre-cat sensor – measures the oxygen levels of gases as they exit the combustion chamber. The amount of fuel entering your engine is then adjusted based on the oxygen levels of your exhaust gas. Oxygen sensors become contaminated as they get older, reducing their ability to properly read and react to your vehicle’s O2/gas mixture. A sudden drop in fuel economy and a “check engine light” are common symptoms of a failed O2 sensor.
