21. Update the ECM/PCM if it does not have the latestsoftware (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
22. Hold the engine speed between 3,000 4,000 rpm for at least 10 seconds.
23. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the knock sensor and the ECM/PCM. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then go to step 22.
If the ECM/PCM was substituted, go to step 1.
Go to step 24.
24. Monitor the OBD STATUS for DTC P0325 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 23, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the knock sensor
and the ECM/PCM. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see page 11-7),
then go to step 22. If the ECM/PCM was substituted,
go to step 1. If the screen indicates NOT
COMPLETED, go to step 22. 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 to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Check for Temporary DTCs or DTCs with the HDS.
Go to step 5.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the CKP sensor and the ECM/PCM.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the CKP sensor 3P connector.
7. Turn the ignition switch to ON (II).
8. Measure the voltage between CKP sensor 3P connector terminal No. 3 and body ground.
Go to step 9.

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 throttle
body, the MAF sensor/IAT sensor, and the ECM/
PCM. If the screen indicates EXECUTING, keep
idling until a result comes on. If the screen
indicates OUT OF CONDITION, go to step 6.
10. Do the ETCS TEST in the INSPECTION MENU with the HDS.

11. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle. 12. Monitor the ENGINE SPEED in the DATA LIST with
the HDS, and hold the engine speed at 2,500 rpm
for at least 30 seconds.
13. While holding the engine speed at 2,500 rpm, check the MAF SENSOR in the DATA LIST with the HDS.
Go to step 14.
Replace the MAF sensor/IAT sensor (see page
11-224), then go to step 20.
14. Turn the ignition switch to LOCK (0).
15. Allow the engine to cool to ambient temperature.
16. Note the ambient temperature.
17. Turn the ignition switch to ON (II).
18. Note the value of IAT SENSOR quickly in the DATA LIST with the HDS.
19. Compare the value of the IAT SENSOR and the ambient temperature.
Replace the MAF sensor/IAT sensor
(see page 11-224), then go to step 20.
Check for dirt, carbon, or damage in the
throttle bore. If there is dirt or carbon, clean the
throttle body (see page 11-344), then go to step 20.
If there is damage in the throttle bore, replace the
throttle body; K20Z2 engine (see page 11-348),
