Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

Go to step 32.

32. Monitor the OBD STATUS for DTC P0453 in the

DTCs MENU with the HDS.

Troubleshooting is complete.

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, go to step 30 and
recheck.

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

software, or substitute a known-good ECM/PCM
(see page 11-6).

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

If DTC P0453 is indicated, check for poor

connections or loose terminals at the FTP sensor
and the ECM/PCM, then go to step 1. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

If the ECM/PCM was updated, troubleshooting
