Lambda Sensor - Front (pre-catalyst oxygen sensor) for the exhaust and engine management system of the 4.2L V8 Supercharged and 4.4L V8 petrol engines.

The sensor is fitted upstream of the catalytic converter and measures residual oxygen in the exhaust gas. Its output is the closed-loop feedback signal the engine control module uses to hold the air/fuel mixture at stoichiometric, which governs both catalyst conversion efficiency and fuel consumption.

The unit is heated, allowing closed-loop control to start shortly after a cold start. A sluggish or contaminated sensor typically presents as raised fuel consumption, rough running or a fuel-trim fault code. It is not serviceable and is replaced complete.

Frequently asked questions

What is this front lambda sensor and what does it do?
It's the front, pre-catalyst lambda sensor for the 4.2L V8 Supercharged and 4.4L V8 petrol engines. Fitted upstream of the catalytic converter, it measures exhaust oxygen to give the closed-loop feedback the ECM uses to hold the air/fuel mixture at stoichiometric. Fits the Range Rover L322.
What are the signs the lambda sensor needs replacing?
A sluggish or contaminated lambda sensor typically presents as raised fuel consumption, rough running or a fuel-trim fault code on the L322 V8. It's heated for early closed-loop control after a cold start, and is replaced complete rather than serviced.
How do I confirm this fits my vehicle?
This front lambda sensor fits the Range Rover L322 (2002-2009) 4.2 V8 Supercharged and 4.4 V8 petrol, in rest-of-world (ROW) specification from VIN 7A00001. Check your VIN and market spec before ordering, as sensors differ between ROW and other markets.
