Lambda symbol

Question : WHAT does the constantly lighted Lambda symbol mean ?

Any effect on engine function ?

Answer : More likely than not, it means that the 02 sensor is faulty.

Another name for the Lambda sensor is 02 sensor and its function is to sample the amount of oxygen in the exhaust system in cars having catalytic convertors.

Its purpose is to enable the fuel injection system to vary the air-fuel mixture such that it is close to the stochiometric ratio for complete combustion of about 14.7kg air per 1kg petrol.

When it fails, the fuel mixture could go "haywire" with either very rich or very lean mixtures with unpleasant results.
