DTC DETECTING CONDITION: Detected when two consecutive driving cycles with fault occur. TROUBLE SYMPTOM: Improper idling 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 This monitor intrusively performs a functional check to detect incorrect purge flow. The monitor seals the EVAP system (i.e. isolate from atmosphere) by closing the ELCM switching valve intrusively after recovering from a fuel cut event. In the case of normal condition, and the commanded purge control duty ratio is more than 0%, ELCM pressure (gauge) will decrease due to engine vacuum and reach to the threshold value. However, in the case of malfunction condition (e.g. fuel cap open, purge valve stuck closed, purge line disconnected or blocked), if the ELCM pressure (gauge) does not reach the threshold within a predetermined time, the monitor determines a malfunction and stores a fault code. Malfunction Criteria ELCM pressure (gauge) > Threshold
2. EXECUTION CONDITION
* It takes approximately 2 min at 40 MPH
3. GENERAL DRIVING CYCLE Perform the diagnosis only once during ordinary driving. 4. DIAGNOSTIC METHOD Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 30000 ms − 10000 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
