terminals at the FTP sensor and the ECM/PCM, then
go to step 1.
Go to step 31.
31. Monitor the OBD STATUS for DTC P0452 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 30,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the FTP sensor
and the ECM/PCM, then go to step 1. If the screen
indicates NOT COMPLETED, keep idling until a
result comes on. 32. Reconnect all connectors.

software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
34. Start the engine, and let it idle.
35. Check for Temporary DTCs or DTCs with the HDS.

good ECM/PCM (see page 11-7), then go to step 34.
If the ECM/PCM was substituted, go to step 1.
Go to step 36.
36. Monitor the OBD STATUS for DTC P0452 in the DTCs MENU with the HDS.
If the ECM/PCM was updated,
troubleshooting is complete. If the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228). If any other Temporary DTCs or
DTCs were indicated in step 35, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the FTP sensor
and the ECM/PCM. If the ECM/PCM was updated,

NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Check the fuel fill cap (the cap must say TIGHTEN TO CLICK). It should turn 1/4 turn after it’s tight,
then it clicks.
Go to step 2.
Replace or tighten the cap, then go to step 19.
2. Check the fuel fill cap seal (A) and the fuel fill pipe mating surface (B). Verify that the fuel fill cap tether
cord (C) is not caught under the cap.
Replace the fuel fill cap or the fuel fill pipe,
then go to step 19.
Go to step 3.
3. Turn the ignition switch to ON (II).
4. Clear the DTC with the HDS. 5. Do the EVAP FUNCTION TEST in the INSPECTION
MENU with the HDS.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the FTP sensor or the EVAP canister vent shut
valve and the ECM/PCM.
Go to step 6.
6. Turn the ignition switch to LOCK (0).
7. Remove the EVAP canister vent shut valve from the EVAP canister (see page 11-409).
8. Connect the 2P connector to the EVAP canister vent shut valve.
9. Turn the ignition switch to ON (II).
10. Select EVAP CVS ON in the INSPECTION MENU with the HDS.
11. Check the EVAP canister vent shut valve (A) operation.
Check the routing of the EVAP canister vent
tube,thengotostep18.
Go to step 12.
