Lambda Sensor - oxygen sensor for the lower, post-catalyst position on the exhaust front pipe, part of the engine management and emissions control system.

Mounted downstream of the catalytic converter, the sensor measures residual oxygen in the exhaust gas and reports it to the engine control module. The module compares this against the upstream sensor signal to assess catalyst conversion efficiency and to correct long-term fuel trim. Fitted to the 2.0L I4 AJ200 petrol engine in mid and high output form.

A degraded sensor commonly presents as an illuminated malfunction indicator lamp with an emissions or catalyst-efficiency fault code.

This lambda sensor is the oxygen sensor for the lower, post-catalyst position on the exhaust front pipe. Mounted downstream of the catalytic converter, it measures residual exhaust oxygen and reports to the engine control module, which compares it against the upstream sensor to assess catalyst efficiency. Fitted to the 2.0L AJ200 petrol on the Discovery Sport.
What are the signs this lambda sensor has failed?
A degraded sensor commonly shows as an illuminated malfunction indicator lamp with an emissions or catalyst-efficiency fault code on the Discovery Sport 2.0L petrol.
Which vehicles does this post-catalyst lambda sensor fit?
Confirmed for the Discovery Sport (2015+) with the 2.0L I4 AJ200 petrol, mid and high output, from VIN JH000001. Use your VIN to confirm the emissions variant before ordering.
