DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B102E:11 | Air Quality Sensor: Circuit Short To Ground | This DTC sets when the FCIM senses lower than expected voltage on the sensor feedback circuit, indicating a short to ground. |
| B102E:15 | Air Quality Sensor: Circuit Short To Battery or Open | This DTC sets when the FCIM senses greater than expected voltage on the sensor feedback circuit, indicating a short to voltage or an open circuit or sensor. |
| B102E:92 | Air Quality Sensor: Performance or Incorrect Operation | This DTC sets when the FCIM senses erratic voltages from the evaporator temperature sensor. |
