Lambda Sensor Default

Specifies a failsafe reading that will be used when the lambda sensor has failed (one or more DTCs are being reported for the sensors).

Note

Lambda is a measure of the air/fuel mixture in the combustion chamber. A lambda value of 1.0 indicates that there is exactly enough oxygen in the combustion chamber to burn the fuel present. Higher values indicate an excess of oxygen (a "lean" mix). Lower values indicate a shortage of oxygen (a "rich" mix).
