NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Turn the ignition switch OFF.

4. Remove the fuel fill cap.

5. Turn the ignition switch ON (II).

6. Check the FTP SENSOR in the DATA LIST with the

HDS.

Go to step 10.

Go to step 7.

7. Install the fuel fill cap.

8. Start the engine.

9. Monitor the OBD STATUS for DTC P0452 in the

DTCs MENU with the HDS.

Go to step 10.

If the screen indicates PASSED, intermittent

failure, the system is OK at this time. Check for
poor connections or loose terminals at the FTP
sensor and the PCM. If the screen indicates NOT
COMPLETED, go to step 5 and recheck.

10. Turn the ignition switch OFF.

12. Turn the ignition switch ON (II).

13. Check the FTP SENSOR in the DATA LIST with the

HDS.

Go to step 24.

Go to step 14.

14. Measure voltage between FTP sensor 3P connector

terminal No. 1 and body ground.

Go to step 20.

Go to step 15.

17. Disconnect PCM connector A (44P).

18. Connect FTP sensor 3P connector terminal No. 1 to

body ground with a jumper wire.

19. Check for continuity between PCM connector

terminal A19 and body ground.

Go to step 32.

Repair open in the wire between the PCM

(A19) and the FTP sensor, then go to step 26.

20. Turn the ignition switch OFF.

21. Jump the SCS line with the HDS.

22. Disconnect PCM connector A (44P).

23. Check for continuity between FTP sensor 3P

connector terminal No. 2 and body ground.

Repair short in the wire between the PCM

(A33) and the FTP sensor, then go to step 26.

Go to step 32.

24. Turn the ignition switch OFF.

25. Replace the FTP sensor (see page 11-374).

26. Reconnect all connectors.

27. Turn the ignition switch ON (II).

DTC Troubleshooting (cont’d)

30. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the FTP sensor and the 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 PCM, then go to step 1. If the screen
indicates NOT COMPLETED, keep idling until a
result comes on.

32. Reconnect all connectors.

33. Update the PCM if it does not have the latest

software (see page 11-7), or substitute a known-
good PCM (see page 11-8).

34. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the FTP sensor and the PCM. If the
PCM was updated, substitute a known-good PCM
(see page 11-8), then recheck. If the PCM was
substituted, go to step 1.

Go to step 34.

35. Monitor the OBD STATUS for DTC P0452 in the

DTCs MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated in step 34,
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 PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-8), then recheck. If
the PCM was substituted, go to step 1. If the screen
indicates NOT COMPLETED, keep idling until a
result comes on.
