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.

APP Sensor Signal Inspection
A
NOTE:
 This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor
stores DTCs which are covered in other
troubleshooting procedure.
 Check for Temporary DTCs or DTCs with the HDS before doing this procedure. If any DTCs are
indicated, troubleshoot them first, then do this
procedure.
 Press the accelerator pedal several times to check its operation. If it does not operate smoothly, check the
pedal. If you find a problem, replace the accelerator
pedal module; K20Z2 engine (see page 11-269),
K20Z3 engine (see page 11-270).
1. Connect the HDS to the data link connector (DLC) (A) located under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the ECM/ PCM. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11- 204).
4. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with
the HDS.
 If it is 0 %, the APP sensor is OK.
 If it is not 0 %, update the ECM/PCM if it does not have the latest software, or substitute a known-
good ECM/PCM (see page 11-7), then go to step
5. 5. With the accelerator pedal not pressed, then check
the APP SENSOR in the DATA LIST with the HDS.
 If it is 0 %, the APP sensor is OK.
 If it is not 0 %, replace the accelerator pedal module; K20Z2 engine (see page 11- 269), K20Z3
engine (see page 11-270), then go to step 1.
