Purge Control System Inspection

If simulation function of M-MDS is used:

1. Start the engine.
2. Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .)
3. Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
4. Put a finger to the purge solenoid valve and verify that there is no vacuum applied when the engine is cold.
   • If there is a vacuum, inspect the following:
     • Wiring harness and connectors (Purge solenoid valve-PCM terminal 1AW)
     • Purge solenoid valve (stuck open) (See PURGE SOLENOID VALVE INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .)
5. Connect the M-MDS to the DLC-2 and verify that DTC P0443:00 is displayed. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .)
   • Perform the DTC inspection. (See DTC P0443:00 [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .)
6. Select the EVAPCP simulation item.
7. Increase the duty value of the purge solenoid valve to 50 % and inspect if the operation sound of the valve is heard.
   • If the operation sound is heard, inspect for loose or damaged vacuum hoses. (Intake manifold- Purge solenoid valve-Charcoal canister)
   • If the operation sound is not heard, perform the purge solenoid valve inspection. (See PURGE SOLENOID VALVE INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .)
8. Warm up the engine to normal operating temperature.
9. Monitor the EVAPCP PID using the M-MDS, and drive the vehicle approx. 2000 RPM for 30 s or more. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .)
   • If the EVAPCP PID is 0 %, inspect the following PIDs:
     • MAF, APP1, APP2, TP REL and LOAD PIDs (See PCM INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .)
