If your oxygen sensor goes bad, your feedback control system reverts to an open loop with a fixed, rich fuel mixture. This causes fuel consumption and emissions to go up. It also may cause damage to the catalytic converter. Replace your O2 sensor for Land Rover approximately every 80,000 miles to ensure peak performance.

An o2 sensor produces its own voltage based on the difference between the amount of oxygen inside the exhaust stream as compared to the oxygen outside the exhaust stream. During combustion inside the engine, oxygen is left over or not left over directly proportional to the amount of fuel burned. A lot of left over oxygen indicates a lean condition and vice versa. It's important to keep your Land Rover oxygen sensor functioning properly. Replacement parts come standard with a 1-Year, Lower Price Guarantee at AutoAnything.
