Frequently asked questions

What is the LR166505 lambda sensor and what does it do?
The LR166505 is a diesel lambda (oxygen) sensor for the Discovery 5 (2017+), Range Rover L405 (2013-2022) and Range Rover Sport L494 (2014-2022). It measures oxygen in the exhaust so the engine management can control fuelling and emissions. Made by Bosch.
Where is this lambda sensor fitted?
On the Discovery 5 the sensor typically sits on the exhaust front pipe and catalyst as a heated exhaust gas oxygen (HEGO) sensor. It threads into the exhaust to sample gas flow. Exact position varies by engine, so check against your vehicle.
What are the signs of a failing lambda sensor?
A failing lambda sensor typically causes a check-engine light, poor fuel economy, rough running, or failed emissions readings, as the engine loses accurate exhaust oxygen data. Fault codes usually point to the specific sensor. Diagnosis with a scan tool confirms it before replacement.
How do I confirm this sensor fits my vehicle?
The LR166505 fits diesel Discovery 5, Range Rover L405 and Range Rover Sport L494 (2.0D, 3.0D and 4.4D per Bosch listing). Check your engine is diesel and confirm the sensor position, as these engines use more than one oxygen sensor. Use your VIN to verify.
