Canister Purge Control Valve: Component Tests and General Diagnostics
Purge Control System Inspection
1. Start the engine.
2. Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
3. 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 2AN)
-
Purge solenoid valve
4. Warm up the engine to the normal operating temperature.
5. Stop the engine.
6. Connect the WDS or equivalent to the DLC-2 and verify that the DTC P0443 is shown. Perform DTC inspection. See: Computers and Control
Systems/Testing and Inspection/Diagnostic Trouble Code Descriptions
7. Turn the ignition switch to the ON position.
8. Access ECT PID.
9. Verify that the engine coolant temperature is more than 78 degrees C (172 degrees F).
-
If the WDS or equivalent indicates less than 78 degrees C 172 degrees F), perform the EOT sensor inspection.
10. Set the vehicle on the dynamometer or chassis roller.
WARNING: When the dynamometer or chassis roller is operating, there is a possibility that the operator may come into contact with or
be caught up in the rotating parts, leading to serious injuries or death. When performing work while the dynamometer or chassis roller is
operating, be careful not to come into contact with or be caught up in any of the rotating parts.
11. Drive vehicle at engine speed approx. 2000 rpm for 30 seconds or more.
12. Put a finger to the purge solenoid valve and verify that there is no vacuum applied while step 2.
-
If there is no vacuum, inspect the following:
-
Wiring harness and connector (Main relay - purge solenoid valve PCM terminal 2AN)
-
Purge solenoid valve
-
MAP, APP1,APP2,TP and LOAD PIDs
-
If there is vacuum, inspect the following:
-
Vacuum hose (Purge solenoid valve - charcoal canister)
