Lambda Sensor for the 3.0L AJ20P6 six-cylinder petrol engine, mounted in the exhaust system as part of the fuelling feedback and emission control circuit. The sensor measures resid ual oxygen in the exhaust gas and reports it to the engine control module, which uses the signal to hold the air/fuel mixture at the correct ratio under closed-loop running. A degraded sensor typically shows as increased fuel consumption, rough running or an illuminated engine management lamp. Show more
