Purge Control System Inspection

If simulation function of M-MDS is used:

Start the engine.
Remove the plug hole plate. (Refer to PLUG HOLE PLATE REMOVAL/INSTALLATION .)
Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
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 1AI)
  - Purge solenoid valve (stuck open) (Refer to PURGE SOLENOID VALVE INSPECTION .)
Connect the M-MDS to the DLC-2 and verify that DTC P0443:00 is displayed. (Refer to ON-BOARD DIAGNOSTIC TEST .)
- Perform the DTC inspection. (Refer to DTC P0443:00 .)
Select the EVAPCP simulation item. (Refer to ON-BOARD DIAGNOSTIC TEST .)
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. (Refer to PURGE SOLENOID VALVE INSPECTION .)
Warm up the engine to normal operating temperature.
Monitor the EVAPCP PID using the M-MDS, and drive the vehicle approx. 2, 000 rpm for 30 s or more . (Refer to ON-BOARD DIAGNOSTIC TEST .)
- If the EVAPCP PID is 0 % , inspect the following PIDs:
  - MAF, APP1, APP2, TP_REL and LOAD PIDs (Refer to PCM INSPECTION .)
