P0112

Tests 1 - 2:

Tests 3 - 8:

Test 9:

SYMPTOM
P0112 - INTAKE AIR TEMPERATURE (IAT) SENSOR VOLTAGE TOO LOW

WHEN MONITORED
With the ignition ON and battery voltage greater than 10.4 volts

SET CONDITION
The intake air sensor circuit voltage at the ECM goes below 0.098 volt for more than 2 seconds.

POSSIBLE CAUSES
- IAT sensor signal circuit shorted to ground
- Intake air temperature sensor ground circuit shorted to ground
- IAT sensor wiring harness intermittent defect
- IAT sensor wiring harness observable defect
- Engine Control Module
- Intake Air Temperature Sensor (resistance < 100 k ohm)
- Intake Air Temperature Sensor (resistance out of range)
