Symptom: P0112-INTAKE AIR TEMP SENSOR TOO LOW When Monitored and Set Condition: P0112-INTAKE AIR TEMP SENSOR TOO LOW When Monitored: With the ignition on. Set Condition: Any time the Inlet Air Temp Sensor Signal circuit voltage is less than 0.10 volt. POSSIBLE CAUSES INTERMITTENT CONDITION IAT SENSOR INTERNAL FAILURE (K21) IAT SENSOR SIGNAL SHORTED TO GROUND (K21) IAT SENSOR SIGNAL SHORTED TO (K921) SENSOR GROUND CIRCUIT PCM TEST ACTION APPLICABILITY 1 Turn the ignition on. t, read the IAT voltage. Is the voltage below 0.10 volt? All Yes → Go To 2 No → Go To 6 2 Turn the ignition off. t, read IAT voltage. Is the voltage approximately 5 volts? All Yes → Replace the Inlet Air Temperature Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L. No → Go To 3 3 Turn the ignition off. All Yes → Repair the short to ground (K21) Inlet Air Temperature Sensor Signal circuit. No → Go To 4 54 DRIVEABILITY - 1.6L GAS |
