PGM-FI System

DTC Troubleshooting (cont’d)

CMP Sensor Intermittent

Interruption

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 ON (II).

2. Clear the DTC with the HDS.

3. Test-drive the vehicle for 10 minutes in the range of

these recorded freeze data parameters:

• ENGINE SPEED
• VSS

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

Go to step 4.

Intermittent failure, the system is OK at this

time. Check for poor connections or loose terminals
at the CMP sensor and the PCM.

5. Check for poor or loose connections at these

connectors and terminals:

• CMP sensor
• PCM
• Engine ground
• Body ground

Go to step 6.

Reconnect or repair the connectors or

terminals, then go to step 9.

6. Check for damage to the CMP sensor pulse

projection on the front camshaft pulley (see page
11-203).

Replace the front camshaft pulley (see page

6-11), then go to step 9.

Go to step 7.

7. Turn the ignition switch OFF.

8. Replace the CMP sensor (see page 11-203).

9. Turn the ignition switch ON (II).

10. Reset the PCM with the HDS.

11. Clear the CKP pattern with the HDS.

12. Do the PCM idle learn procedure (see page 11-273).

13. Do the CKP pattern learn procedure (see page 11-4).

14. Test-drive the vehicle for 10 minutes in the range of

these recorded freeze data parameters:

• ENGINE SPEED
• VSS

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

Check for poor connections or loose

terminals at the CMP sensor and the PCM, then go
to step 1.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

DTC P0562:

YES

11-121

Charging System Low Voltage

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

• If any high current load accessories are installed, this

DTC can be set.

• If DTC P16BB and/or P16BC is stored at the same time

as DTC P0562, troubleshoot DTC P16BB and/or P16BC
first, then recheck for DTC P0562.

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine.

4. Check under these conditions:

• A/C on
• Temperature control at maximum cool
• Blower fan at maximum speed
• Headlights on high beam

5. Hold the engine speed at 2,000 rpm (in Park or

neutral) for 1 minute.

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

Replace the alternator (see page 4-34), then

go to step 7.

Intermittent failure, the system is OK at this

time. Check for poor connections or loose terminals
at the alternator and the under-hood fuse/relay box,
and check the battery performance (see page
22-74).

7. Turn the ignition switch ON (II).

8. Reset the PCM with the HDS.

9. Do the PCM idle learn procedure (see page 11-273).

10. Start the engine.

11. Check under these conditions:

• A/C on
• Temperature control at maximum cool
• Blower fan at maximum speed
• Headlights on high beam

12. Hold the engine speed at 2,000 rpm (in Park or

neutral) for 1 minute.

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

Check for poor connections or loose

terminals at the alternator and the under-hood
fuse/relay box, then go to step 1.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
