Heated Oxygen Sensor (Ho2S) Activation Requirements

WARNING: This page is about a different variant/trim than selected.
NOTE: If the sensor has not become active, then DTCs will not be set.

The drive cycle required to activate all of the Heated Oxygen Sensor (HO2S) can vary greatly in time. This is dependent on all of the sensors reaching 'dew point' during previous drive cycles. 'Dew point' is where the moisture content in the exhaust has evaporated and can no longer damage the Heated Oxygen Sensor (HO2S). The closer a Heated Oxygen Sensor (HO2S) is to the engine, the faster it will achieve 'dew point'. When a Heated Oxygen Sensor (HO2S) has reached 'dew point' the Heated Oxygen Sensor (HO2S) heating is activated and shortly afterwards the Heated Oxygen Sensor (HO2S) will be functional. When functional the Heated Oxygen Sensor (HO2S) diagnostics become active and can report any error states with a DTC.
