P0112
Test 1 - 3:
Test 4 - 5:
SYMPTOM
P0112-INTAKE AIR TEMP SENSOR VOLTAGE TOO LOW
WHEN MONITORED
With the ignition on and battery voltage greater than 10.4 volts.
SET CONDITION
The Intake Air Temperature (IAT) Sensor circuit voltage at the PCM goes below 0.8 of a volt.
POSSIBLE CAUSES
- IAT sensor voltage below 1.0 Volt
- IAT sensor
- (K21) IAT sensor signal circuit shorted to ground
- (K21) IAT sensor signal shorted to (K4) sensor ground circuit
- PCM
