Test 11:

SYMPTOM
EVAPORATOR SENSOR FAILURE - ATC and MTC

WHEN MONITORED
With the ignition on.

SET CONDITION
This DTC will set if the BCM detects voltage below 0.06 volts or above 4.8 volts on the evaporator temperature sensor signal input.

POSSIBLE CAUSES
- Evaporator temperature sensor signal CKT short to voltage
- Evaporator temperature sensor open
- Evaporator temp sensor signal CKT open
- Sensor ground open
- Body control module - evaporator temp sensor stays high
- Evaporator temperature sensor
- Intermittent wiring problem
- Evaporator temp sensor signal circuit short to ground
- Evaporator temp sensor signal CKT short to sensor ground
- Body control module - evaporator temp sensor stays low
