Symptom: P0111-INTAKE AIR TEMPERATURE SENSOR PERFORMANCE When Monitored and Set Condition: P0111-INTAKE AIR TEMPERATURE SENSOR PERFORMANCE When Monitored: The engine off time is greater than 480 minutes. Ambient Temperature is greater than 4 deg C (38 deg F). Set Condition: After a calibrated amount of cool down time the PCM compares the ECT Sensor, IAT Sensor, and the Ambient Air Temp Sensor values. The IAT Sensor value is not POSSIBLE CAUSES GOOD TRIP EQUAL TO ZERO (K21) IAT SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE IAT SENSOR (K21) IAT SIGNAL CIRCUIT OPEN (K900) SENSOR GROUND CIRCUIT OPEN (K21) IAT SIGNAL CIRCUIT SHORTED TO GROUND (K21) IAT SIGNAL CIRCUIT SHORTED TO THE (K900) SENSOR GROUND PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read DTCs and record the related Freeze Frame data. Is the Good Trip Counter displayed and equal to zero? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION Symptom (Diagnos- tic Procedure). 2 Turn the ignition off. All Yes → Repair the short to voltage in the (K21) IAT Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 3 61 DRIVEABILITY - NGC |
