Walker Products Oxygen Sensor P/N:250-25144
Walker Products 250-241141 center left oxygen sensor for the 2022-2025 Land Rover Defender 110 V8 5.0L and other vehicles measures the oxygen in the exhaust gas. The engine control unit gets diagnostic feedback from that reading.
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, because a damaged wiring harness or connector can produce the same ones.
As a center left oxygen sensor, it fits the 2022-2025 Land Rover Defender 110 V8 5.0L, the 2022-2025 Land Rover Defender 90 V8 5.0L and the 2024-2025 Land Rover Defender 130 V8 5.0L. This listing is one sensor, and the 2022-2025 Land Rover Defender 110 V8 5.0L takes one in this position; a sensor for any other position is a separate order. If your Land Rover is not named here, look it up by year and engine in the "Vehicles it fits" section.
