11-349).

22. Start the engine.

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

If DTC P0365 is indicated, check for poor

connections or loose terminals at CMP sensor B
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.

Troubleshooting is complete.

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

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

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

If DTC P0365 is indicated, check for poor

connections or loose terminals at CMP sensor B
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

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).

CMP Sensor B Circuit Intermittent

Interruption
(2005-2006 models)

1. Record all freeze data and on-board snapshots with

the HDS.

2. Clear the DTC with the HDS.

3. Start the engine, and let it idle for 10 seconds.

4. Check the CMP NOISE B COUNT in the DATA LIST

with the HDS.

Go to step 7.

Go to step 5.

5. Test-drive the vehicle for several minutes in the

range of these recorded freeze data parameters:

• Engine speed
• Vehicle speed

6. Check the CMP NOISE B COUNT in the DATA LIST

with the HDS.

Go to step 7.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
CMP sensor B and the ECM/PCM.

7. Check for poor or loose connections and terminals

at these locations:

• CMP sensor B
• ECM/PCM
• Engine ground
• Body ground

Go to step 8.

Repair the connectors or terminals, then go to

step 11.

8. Check the CMP sensor B pulse plate for damage

(see page 6-33).

Replace the CMP sensor B pulse plate

(see page 6-33), then go to step 11.

Go to step 9.

9. Turn the ignition switch OFF.

10. Replace CMP sensor B (see page 11-281).

11. Turn the ignition switch ON (II).

12. Reset the ECM/PCM with the HDS.

13. Do the ECM/PCM idle learn procedure (see page

11-349).

14. Start the engine, and let it idle for 10 seconds.

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

If DTC P0369 is indicated, check for poor

connections or loose terminals at CMP sensor B
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.

Troubleshooting is complete.

Ar e 0 counts indicated?

Ar e the connections and ter minals OK ?

VSS Circuit Malfunction

(2002-2004 models)

1. Test-drive the vehicle.

2. Check the vehicle speed with a scan tool or the HDS.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
the VSS and the ECM.

Go to step 3.

3. Turn the ignition switch OFF.

4. Block the rear wheels and set the parking brake.

5. Raise the front of the vehicle, and make sure it is

securely supported.

6. Turn the ignition switch ON (II).

7. Block the right front wheel, and slowly rotate the

left front wheel.

8. Measure voltage between ECM connector

terminals A18 and A24.

Update the ECM if it does not have the latest

software, or substitute a known-good ECM
(see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM,
replace the original ECM (see page 11-284).

Go to step 9.

9. Turn the ignition switch OFF.

10. Disconnect ECM connector A (31P).

11. Turn the ignition switch ON (II).

12. Block the right front wheel, and slowly rotate the

left front wheel.

13. Measure voltage between ECM connector

terminals A18 and A24.

Update the ECM if it does not have the latest

software, or substitute a known-good ECM
(see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM,
replace the original ECM (see page 11-284).

Check for a short or an open in the wire

between the ECM (A18) and the VSS. If the wire is
OK, test the VSS (see page 22-75).

Wire side of female terminals

Is the cor r ect speed indicated?

Does the voltage pulse between 0 V and 5 V or
batter y voltage?
