Evaporator Sensor Failure

Test 1:

Test 2 - 5:

Test 6 - 9:

Test 10 - 14:

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 sensor signal CKT
- Evaporator temp sensor signal CKT - short to ground
- Evaporator temperature sensor signal - short to battery
- Evaporator temp sensor IAC system
- Evaporator temp sensor/ BCM codes - reconnected
- EVAPORATOR temp SENSOR - signal grounded
- BCM/EVAP temp sensor signal CKT SH/GND
- BCM/OPEN EVAP temp sensor signal CKT
- BCM/sensor GND CKT
- System ok at this time
