1. OUTLINE OF DIAGNOSIS Detect the drain filter clogging by the pressure change during purge introduction. Judge as drain filter clogging malfunction if the pressure in the evaporative emission system piping suddenly decreases by the purging. 2. COMPONENT DESCRIPTION
3. EXECUTION CONDITION
4. GENERAL DRIVING CYCLE Perform the diagnosis continuously when purging is performed after 20000 ms have passed since the engine started. 5. DIAGNOSTIC METHOD Calculate the difference between the ELCM pressure sensor output value as of 5 seconds ago and the current one, and if the value is greater than judgment value, detect and judge as filter clogging trouble. Judge as NG when the following conditions are established.
Time Needed for Diagnosis: Approx. 5.5 seconds Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
