The sensor voltage changes very quickly when the lambda value exceeds 1.
The lambda control factor is 1.00 when the lambda control is inactive. As soon as the lambda control is activated the oxygen sensor voltage is allowed to
affect the control correction factor. If the sensor voltage is less than 0.50 V (weak mixture) the correction factor will slowly be raised, i.e. more petrol is
injected. Conversely the correction factor will slowly be lowered if the sensor voltage exceeds 0.50 V.
