NOTE:

• Before you troubleshoot, record all freeze data and

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

• Information marked with an asterisk ( ) applies to the

front bank (Bank 2).

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle 2 minutes.

4. Check for Temporary DTCs or DTCs 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/F sensor (Sensor 1) and the PCM.

5. Turn the ignition switch OFF.

6. Jump the SCS line with the HDS.

7. Disconnect the A/F sensor (Sensor 1) 8P connector.

8. Disconnect PCM connector B (44P).

9. Check for continuity between PCM connector

terminal B38 (B22) and body ground.

Repair short in the wire between the PCM

(B38 (B22) ) and the A/F sensor (Sensor 1), then go
to step 14.

Go to step 10.

10. Reconnect PCM connector B (44P).

11. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the

12. Measure voltage between A/F sensor (Sensor 1) 8P

connector terminal No. 8 and body ground.

Go to step 20.

Go to step 13.

13. Replace the A/F sensor (Sensor 1) (see page

11-199).

14. Reconnect all connectors.

15. Turn the ignition switch ON (II).

16. Reset the PCM with the HDS.

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

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

Check for poor connections or loose

terminals at the A/F sensor (Sensor 1) and the PCM,
then go to step 1.

Go to step 19.

19. Monitor the OBD STATUS for DTC P2245 and/or

P2249 in the DTCs MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated in step 18,
go to the indicated DTC’s troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the A/F sensor
(Sensor 1) and the PCM, then go to step 1. If the
screen indicates NOT COMPLETED, keep idling
until a result comes on.

20. Turn the ignition switch OFF.

21. Reconnect all connectors.

22. Update the PCM if it does not have the latest

software (see page 11-7), or substitute a known-
good PCM (see page 11-8).

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

Check for poor connections or loose

terminals at the A/F sensor (Sensor 1) and the PCM.
If the PCM was updated, substitute a known-good
PCM (see page 11-8), then recheck. If the PCM was
substituted, go to step 1.

Go to step 24.

24. Monitor the OBD STATUS for DTC P2245 and/or

P2249 in the DTCs MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated in step 23,
go to the indicated DTC’s troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the A/F sensor
(Sensor 1) and the PCM. If the PCM was updated,
substitute a known-good PCM (see page 11-8), then
recheck. If the PCM was substituted, go to step 1. If
the screen indicates NOT COMPLETED, keep idling
until a result comes on.
