Land Rover Part Number: LR140073 - Lambda Sensor
LR140073 is a Lambda sensor fitted into the exhaust system of 3.0L and 5.0L petrol engines. It measures the oxygen content of the exhaust gas and provides a voltage signal to the engine control unit so the air-fuel ratio can be adjusted; this feedback is used alongside catalytic converter control and closed-loop fuel management to meet emissions requirements such as SULEV and EU6.
