Evaporator Sensor Failure

SYMPTOM
EVAPORATOR SENSOR FAILURE

WHEN MONITORED
With the ignition key on and battery voltage greater than 10 Volts.

SET CONDITION
Input voltage is above 4.88 Volts (open sensor) or input voltage is below 0.313 Volts (shorted sensor) for more than 10 seconds.

POSSIBLE CAUSES
- Open sensor ground CKT- BCM to sensor
- No response/CCD bus failure (BCM)
- No response/CCD bus failure (PCM)
- Open EVAP TEMP SEN SIG CKT
- Evaporator TEMP sensor SIG CKT - short to ground
- Evaporator temperature sensor signal - short to battery
- Evaporator TEMP SEN/AC system
- Evaporator TEMP SEN/BCT codes - reconnected
- Evaporator TEMP sensor - signal grounded
- BCM/EVAP TEMP SEN SIG CET SH/GND
- BCM/open EVAP TEMP SEN SIG CKT
- BCM/sensor GND CKT
- System OK at this time
