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
indicates EXECUTING, keep idling until a result
comes on. If the screen indicates OUT OF
CONDITION, recheck with different load conditions
(turn on the headlights, blower motor, or A/C;
change the gear position, etc.), then go to step 9.

12. 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).

13. 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.

14. 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 13.
If the ECM/PCM was substituted, go to step 1.

Go to step 15.

15. Monitor the OBD STATUS for DTC P0507 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 14, 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 13. 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 13.

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

1. Start the engine, and let it idle.

2. Turn the blower switch on.

3. Turn the A/C switch on.

4. Check the A/C PRESSURE SENSOR in the DATA

LIST 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 A/C pressure sensor and the ECM/PCM.

5. Turn the ignition switch to LOCK (0).

6. Disconnect the A/C pressure sensor 3P connector.

7. Turn the ignition switch to ON (II).

8. Check the A/C PRESSURE SENSOR in the DATA

LIST with the HDS.

Go to step 10.

Go to step 9.
