Land Rover Part Number: MHK500960 - Lambda Sensor
MHK500960 is a Lambda Sensor fitted in the exhaust system to monitor the oxygen content of exhaust gases on the Cologne 4.0 Petrol V6 and AJ Petrol 4.4 and 4.2 V8 engines. It provides the engine control unit with an oxygen signal to support closed-loop fuel control and catalyst management; a failing sensor can raise emissions, alter fuel trim and economy, and may illuminate the engine warning lamp.
