15. Monitor the OBD STATUS for DTC P2238 in the
DTCs MENU with the HDS.
Troubleshooting is complete. 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 A/F sensor
(Sensor1)andtheECM/PCM,thengotostep1.If
the screen indicates NOT COMPLETED, keep idling
until a result comes on.
16. 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).
17. Start the engine, and let it idle.
18. Check for Temporary DTCs or DTCs with the HDS.
If the ECM/PCM was updated, substitute a
known-good ECM/PCM (see page 11-7), then go to
step 17. If the ECM/PCM was substituted, go to step
1.
Go to step 19.
19. Monitor the OBD STATUS for DTC P2238 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 18, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, go to step 1. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then go to step 17.
If the ECM/PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, keep idling
until a result comes on. 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.
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 ECM/PCM.
5. Turn the ignition switch to LOCK (0).
6. Jump the SCS line with the HDS.
7. Disconnect the A/F sensor (Sensor 1) 4P connector.
8. Disconnect ECM/PCM connector C (44P).
