14. Monitor the OBD STATUS for DTC P0506 in the
DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 13,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, go to step 19. If
the screen indicates EXECUTING, keep idling until
a result comes on. If the screen indicates OUT OF
CONDITION, go to step 11.
15. Remove the intake air duct from the throttle body; K20Z2 engine (see page 11-348), K20Z3 engine
(see page 11-349).
16. Check for dirt, carbon, or damage in the throttle bore.
If there is dirt or carbon, clean the throttle
body (see page 11- 344). Also check for damage to
the air cleaner element (see page 11-346), then go
to step 9. If there is damage in the throttle bore, go
to step 8.
Go to step 17.
17. Recheck with different load conditions (turn on the headlights, blower motor, rear window defogger
and/or A/C, change the gear position, etc.).
18. Monitor the OBD STATUS for DTC P0506 in the DTCs MENU with the HDS.
Intermittent failure, the system is OK at this
time.
If the screen indicates FAILED, check the A/C
system and/or the charging system, then go to step
1 and recheck. If the screen indicates EXECUTING,
keep idling until a result comes on. If the screen
indicates OUT OF CONDITION, go to step 17. 19. Update the ECM/PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
20. 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.
21. Check under these DATA LIST conditions with the HDS:
 ECTSENSOR1above70°C(156°F)
 IAT SENSOR above 0 °C (32 °F)
 VSSis0km/h(0mph)
 ST FUEL TRIM between 0.69 1.47
 FSS is CLOSED
22. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the throttle body and the ECM/PCM. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then go to step 20.
If the ECM/PCM was substituted, go to step 1.
Go to step 23.
23. Monitor the OBD STATUS for DTC P0506 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 22, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the throttle body
and the ECM/PCM. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see page 11-7),
then go to step 20. If the ECM/PCM was substituted,
go to step 1. If the screen indicates EXECUTING,
keep idling until a result comes on. If the screen
indicates OUT OF CONDITION, go to step 20.

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. 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 for at least 20 seconds.
4. Monitor the OBD STATUS for DTC P0507 in the DTCs MENU with the HDS.
Go to step 5.
If the screen indicates PASSED, intermittent
failure, the system is OK at this time. If the screen
indicates EXECUTING, keep idling until a result
comes on. If the screen indicates OUT OF
CONDITION, recheck with different load conditions
(electrical, A/C, gear position, etc.), then go to
step 3.
5. Check for vacuum leaks at these parts:  PCV valve
 PCV hose
 EVAP canister purge valve
 Throttle body
 Intake manifold
 Brake booster hose
 Brake booster
Repair or replace the leaking part(s), then go
to step 6.
Go to step 6. 6. Turn the ignition switch to ON (II).
7. Reset the ECM/PCM with the HDS.
8. Do the ECM/PCM idle learn procedure (see page
11-310).
9. 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 for at least 20 seconds.
10. Check for Temporary DTCs or DTCs with the HDS.
Go to step 12.
Go to step 11.
11. Monitor the OBD STATUS for DTC P0507 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 10,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the throttle body
and the ECM/PCM, then go to step 1. If the screen

Idle Speed Inspection (cont’d) ECM/PCM Idle Learn Procedure
4. 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.
5. Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air
conditioner off.
6. Let the engine idle for 1 minute with high electric load (A/C switch on, temperature set to max cool,
blower fan on high, and headlights on high beam).
NOTE: If the idle speed is not within specification,
dotheECM/PCMidlelearnprocedure(seepage
11-310). If the idle speed is still not within
specification, go to the symptom troubleshooting.
7. Reconnect the EVAP canister purge valve connector. The idle learn procedure must be done so the ECM/PCM
can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of
these actions:
 Replace the ECM/PCM.
 Reset the ECM/PCM.
 Update the ECM/PCM.
 Replace or clean the throttle body.
 Disassemble the engine or the transmission.
NOTE: Erasing DTCs with the HDS does not require you
to do the idle learn procedure.
1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch to ON (II), and wait 2 seconds.
4. 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, or until the
engine coolant temperature reaches 90 °C (194 °F).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include
its running time in the 5 minutes.
