Narrow-Band Lambda Sensor

If using a simple narrow band sensor (that outputs 0-1V depending on mixture being rich/lean) then connect its signal wire directly to your chosen Analog V input, and its ground to the sensor ground pin of the ECU.


It may also have a heater element. Connect one wire of this to the chassis ground, and other to the power feed for the fuel pump, so that the heater only operates when the engine is running.


For more information on configuring Lambda sensors please see the Lambda Sensors section.
