Lambda Sensor for the 3.0L AJ20P6 six-cylinder petrol engine, mounted in the exhaust system as part of the fuelling feedback and emission control circuit.

The sensor measures residual oxygen in the exhaust gas and reports it to the engine control module, which uses the signal to hold the air/fuel mixture at the correct ratio under closed-loop running. A degraded sensor typically shows as increased fuel consumption, rough running or an illuminated engine management lamp.

Frequently asked questions

What does the lambda sensor do?
The lambda or oxygen sensor measures oxygen in the exhaust and feeds the ECU so it can trim the air-fuel mixture for clean, efficient running. It fits the 3.0L AJ20P6 six-cylinder petrol engine and sits in the exhaust system.
Which models does this lambda sensor fit?
This lambda sensor fits 3.0L AJ20P6 petrol engines in the Discovery 5, New Defender L663, Range Rover L405 (from VIN KA000001) and Range Rover Sport L494 (from VIN KA000001). It's specific to the petrol six, so confirm your engine before ordering.
What are the symptoms of a failing lambda sensor?
A failing lambda sensor typically triggers the engine warning light, rough idle, higher fuel use and failed emissions tests. Because the ECU relies on its readings to set fuelling, a faulty sensor can hurt economy and performance even when the engine is otherwise healthy.
Can I replace the lambda sensor myself?
Replacing a lambda sensor is usually a DIY job with a lambda or open spanner, though it can seize in a hot exhaust and may need penetrating oil. This engine has several oxygen sensors, so identify the correct one before fitting.
