3.2TL TYPE S V6-3.2L SOHC (2002)
Oxygen Sensor: Description and Operation
Secondary Oxygen Sensor
Secondary Heated Oxygen Sensor (Secondary HO2S)
The secondary HO2S detects the oxygen content in the exhaust gas in the downstream of the Three Way Catalytic Converter (TWC) and sends signals to
the PCM which varies the duration of injection accordingly. To stabilize its output, the sensor has an internal heater. The secondary HO2S is installed in
the TWC.
