Symptom: P0112-INTAKE AIR TEMPERATURE SENSOR LOW When Monitored and Set Condition: P0112-INTAKE AIR TEMPERATURE SENSOR LOW When Monitored: With the ignition on. Battery voltage greater than 10 volts. Set Condition: The Intake Air Temperature (IAT) sensor voltage is less than 0.0784 of a volt. One trip Fault. POSSIBLE CAUSES IAT SENSOR VOLTAGE BELOW 1.0 VOLT IAT SENSOR INTERNAL FAILURE (K21) IAT SIGNAL SHORTED TO GROUND (K21) IAT SIGNAL SHORTED TO (K4) SENSOR GROUND CIRCUIT PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read the IAT Sensor voltage. Is the voltage below 1.0 volt? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION symptom in the Driveability category. 2 Turn the ignition off. t, read IAT Sensor voltage. Is the voltage above 1.0 volt? All Yes → Replace the IAT Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 3 3 Turn the ignition off. All Yes → Repair the short to ground in the (K21) IAT Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 4 62 DRIVEABILITY - NGC |
