Lambda Sensor – Rear – LH for petrol V6 and V8 engines, fitted in the exhaust downstream of the catalytic converter on the left-hand bank.

This post-catalyst sensor measures the oxygen content of the exhaust gas after the catalyst, allowing the engine control unit to assess catalytic converter efficiency and verify the upstream fuelling correction.

Vehicle Model Land Rover Discovery 3 2005-2009 (L319)
Range Rover Sport 2005-2013 (L320)

Fitment Notes DISCOVERY 3 2005-2009 — Lambda sensor, rear LH, petrol engines: 4.0 V6, 4.4 V8 AJ
RANGE ROVER SPORT 2005-2009 — Lambda sensor, rear LH, petrol engines: 4.2 V8 Supercharged, 4.4 V8 AJ

Frequently asked questions

What is the MHK500910 lambda sensor used for?

The MHK500910 is the rear (post-catalyst) lambda sensor for the left-hand bank, fitted downstream of the catalytic converter on petrol V6 and V8 engines. It measures exhaust oxygen after the catalyst, letting the ECU assess catalytic converter efficiency and verify the upstream fuelling correction.

Which models and engines does this rear LH lambda sensor fit?

This rear left-hand lambda sensor fits the Discovery 3 (2005-2009) with 4.0 V6 and 4.4 V8 AJ petrol engines, and the Range Rover Sport (2005-2009) with 4.2 V8 Supercharged and 4.4 V8 AJ petrol. It's specific to the post-catalyst, left-hand bank position. Confirm your engine before ordering.

How do I know if I need the rear LH lambda sensor or another position?

This is the rear (post-catalyst), left-hand bank sensor. These V6 and V8 engines use several lambda sensors, upstream and downstream on each bank, so the front/rear and LH/RH position matters. Check which sensor your fault code or location refers to before ordering, as they aren't interchangeable.

What are the symptoms of a failed rear lambda sensor?

A failed rear lambda sensor typically triggers the engine warning light and a catalyst efficiency fault code on the Discovery 3 or Range Rover Sport petrol. Because it monitors the catalyst rather than controlling fuelling, running usually stays close to normal, but emissions readings can be affected. Replacing it usually clears the fault.
