Oxygen Sensor (Lambda Sond) Voltage Vs. Exhaust Oxygen Content
SIGNAL
The sensor signal voltage is in direct proportion to the amount of oxygen in the exhaust gases. This depends on the air/fuel ratio. A "Lambda" value of 1
represents the theoretically perfect ratio. A rich mixture results in a higher voltage then a lean mixture.
The voltage produced by the oxygen sensor varies between 0.1 - 1.0V. The fuel injection ECU uses this information to adjust the amount of fuel injected.
