Oxygen Sensor: Description and Operation
DESCRIPTION AND OPERATION
The Heated Oxygen Sensor (HO2S) detects the oxygen content in the exhaust gas and signals the ECM (Engine Control Module). In operation, the
ECM receives the signals from the sensor and varies the duration during which fuel is injected. To stabilize the sensor's output, the sensor has an
internal heater.
