Normal Operation and Fault Conditions
Evaporator Temperature Sensor, REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1B71:11 | Evaporator Temperature Sensor: Circuit Short To Ground | The module senses excessive voltage drop on the sensor reference voltage circuit, indicating a short directly to ground. The module defaults to calculated evaporator temperature and the compressor is shut off. |
| B1B71:15 | Evaporator Temperature Sensor: Circuit Short To Battery or Open | The module senses no voltage drop on the sensor reference voltage circuit, indicating a short directly to voltage or an open circuit. The module defaults to calculated evaporator temperature and the compressor is shut off. |
