New oxygen sensors can reduce emissions, maximize fuel economy and boost engine performance. With gas prices skyrocketing, you can’t afford to drive around with outdated O2 sensors!
Each Land Rover Discovery 2 requires four (4) oxygen sensors. Two of these sensors are mounted in front of the Land Rover’s catalytic converter and two behind it. The front O2 sensor or pre-cat sensor measures the oxygen levels of gases leaving the combustion chamber. The amount of fuel entering your engine is then adjusted based on the oxygen levels of your exhaust gas. As an oxygen sensor ages, it becomes contaminated, reducing its ability to 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.
We recommend replacing your oxygen sensors every 60k miles. O2 sensors should be bought in pairs; two front sensors and two rear sensors. For Discovery 2 rear sensors Click Here.
