13. Check for continuity between ECM/PCM connector

terminal A11 and body ground.

Update the ECM/PCM if it does not have the

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

Repair open in the wire between the ECM/

PCM (A11) and the MAP sensor.

14. Turn the ignition switch OFF.

15. Connect ECM/PCM connector terminals A11 and

A19 with a jumper wire.

16. Turn the ignition switch ON (II).

17. Check the MAP with a scan tool or the HDS.

Update the ECM/PCM if it does not have the

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

Repair open in the wire between the ECM/

PCM (A19) and the MAP sensor.

1. Turn the ignition switch ON (II).

2. Check the MAP SENSOR in the DATA LIST with the

HDS.

Go to step 3.

Intermittent failure, system is OK at this time.

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

3. Turn the ignition switch OFF.

4. Disconnect the MAP sensor 3P connector.

5. Connect MAP sensor 3P connector terminals No. 2

and No. 3 with a jumper wire.

6. Turn the ignition switch ON (II).

7. Check the MAP SENSOR in the DATA LIST with the

HDS.

Go to step 8.

Go to step 19.

8. Remove the jumper wire from the MAP sensor 3P

connector.

9. Measure voltage between MAP sensor 3P

connector terminals No. 1 and No. 3.

Go to step 15.

Go to step 10.

10. Turn the ignition switch OFF.

11. Jump the SCS line with the HDS.

12. Disconnect ECM/PCM connector A (31P).

13. Connect MAP sensor 3P connector terminal No. 3

to body ground with a jumper wire.

14. Check for continuity between ECM/PCM connector

terminal A24 and body ground.

Go to step 26.

Repair open in the wire between the ECM/

PCM (A24) and the MAP sensor, then go to step 21.

15. Turn the ignition switch OFF.

16. Connect ECM/PCM connector terminals A24 and

A30 with a jumper wire.

17. Turn the ignition switch ON (II).

18. Check the MAP SENSOR in the DATA LIST with the

HDS.

Go to step 26.

Repair open in the wire between the ECM/

PCM (A30) and the MAP sensor, then go to step 22.

19. Turn the ignition switch OFF.

20. Replace the MAP sensor (see page 11-412).

21. Reconnect all connectors.

22. Turn the ignition switch ON (II).

23. Reset the ECM/PCM with the HDS.

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

11-349).

25. Check for Temporary DTCs or DTCs with HDS.

If DTC P0108 is indicated, check for poor

connections or loose terminals at the MAP sensor
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.

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

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

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

If DTC P0108 is indicated, check for poor

connections or loose terminals at the MAP sensor
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).
