ο‘
ο‘
ο‘
ο‘
1. Turn the ignition switch to LOCK (0).
2. Install the parts in the reverse order of removal.
3. Turn the ignition switch to ON (II).
4. Reset the PCM with the HDS See HOW TO TROUBLESHOOT THE A/T SYSTEM or HOW
TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS .
ο‘
ο‘
5. DO THE PCM IDLE LEARN PROCEDURE .
6. Select the EVAP TEST in the INSPECTION MENU, and do the FUNCTION TEST with the HDS.
Is the result OK?
YES : Troubleshooting is complete.
NO : Check for poor connections or loose terminals at the FTP sensor, the EVAP canister purge valve, the
EVAP canister vent shut valve, and the PCM, then go to step 1.

Is there about 25 -30 ohms at room temperature?
YES : The EVAP canister vent shut valve is OK. Go to step 5.
NO : REPLACE THE EVAP CANISTER VENT SHUT VALVE , then do the repair verification .
5. Shorted wire check (VSV line):
ο‘
ο‘
ο‘
1. Turn the ignition switch to LOCK (0).
2. Jump the SCS line with the HDS.
3. Disconnect the following connector.
PCM connector A (49P)
ο‘
4. Check for continuity between test points 1 and 2.
Test condition IG LOCK (0)
EVAP canister vent shut valve 2P connector: disconnected
PCM connector A (49P): disconnected
Test circuit VSV

ο‘
ο‘
ο‘
1. Turn the ignition switch to LOCK (0).
2. Reconnect all connectors.
3. Turn the ignition switch to ON (II).
4. Reset the PCM with the HDS See HOW TO TROUBLESHOOT THE A/T SYSTEM or HOW
TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS .
ο‘
ο‘
5. DO THE PCM IDLE LEARN PROCEDURE .
6. Select EVAP TEST in the INSPECTION MENU, and do the EVAP CVS ON in the SINGLE
SOLENOID with the HDS.
ο‘
7. Monitor the OBD STATUS for DTC P0498 in the DTCs MENU with the HDS.
DTC Description
OBD STATUS
P0498 EVAP CANISTER VENT SHUT VALVE CIRCUIT LOW VOLTAGE
Does the HDS indicate PASSED, FAILED, or NOT COMPLETED?
PASSED : Troubleshooting is complete. If the PCM was substituted, replace the original PCM See PCM
REMOVAL AND INSTALLATION or PCM UPDATE . If any other Pending or Confirmed DTCs are
indicated, go to the indicated DTC's troubleshooting.
FAILED : Go to step 1 and recheck. If the PCM was updated, substitute a known-good PCM See PCM
REMOVAL AND INSTALLATION or PCM UPDATE , then check the OBD STATUS again.
NOT COMPLETED : Meet the test condition, and check the OBD STATUS again.
