DTC DETECTING CONDITION: Detected when two consecutive driving cycles with fault occur. CAUTION: After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION, and Inspection Mode Inspection Mode > PROCEDURE.
1. OUTLINE OF DIAGNOSIS Detect the malfunction of ambient temperature sensor characteristics. After the engine starts after the specified period of soaking time has elapsed, judge by correlation between ambient temperature sensor value, intake air temperature sensor value and engine coolant temperature sensor value. Judge as NG when the differences are both above the specified value by comparing between ambient air temperature and intake air temperature, ambient air temperature and engine coolant temperature. 2. COMPONENT DESCRIPTION Ambient temperature sensor is connected to combination meter. ECM receives the data of ambient temperature sensor via CAN communication with combination meter.
3. EXECUTION CONDITION
4. GENERAL DRIVING CYCLE Perform the diagnosis only once after the engine starts after a certain period of soaking time. 5. DIAGNOSTIC METHOD If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Time Needed for Diagnosis: Less than 1 second Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
