Oxygen Sensor: Description and Operation
DESCRIPTION AND OPERATION
The Heated Oxygen Sensors (HO2S) detect the oxygen content in the exhaust gas and signal the PCM. In operation, the PCM 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. The
Primary HO2S (Sensor 1) is installed in the exhaust pipe A.
