Heated Oxygen Sensor (HO2S) Description and Operation
| Description |
| • |
Heated Oxygen Sensor (HO2S), consisting of zirconium and alumina, is installed on both upstream and
downstream of the Manifold Catalytic Converter (MCC) to detect the air/fuel ratio and send it to the Engine
Control Module (ECM).
|
| • |
In order that this sensor operates properly, the temperature of the sensor tip must be higher than 370°C
(698°F).
For this reason, a heater controlled by the ECM duty signal, is built into the sensor.
|
| • |
When the exhaust gas temperature is lower than the specified value, the heater warms the sensor tip.
