WHAT does the constantly lighted Lambda symbol mean ?
Any effect on engine function ?
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
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.
