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. Hold the engine speed at 3,000 rpm (A/T in P or N, M/T in neutral) until the
radiator fan comes on, then let it idle.
4. Test-drive under these conditions:  Engine coolant temperature (ECT SENSOR 1)above70°C(158°F)
 A/TinD,M/Tin4th
 Vehicle speed at 56 km/h (35 mph)
 Drive about 15 seconds
5. Monitor the OBD STATUS for DTC P0139 in the DTCs MENU with the HDS.
Go to step 6.
If the screen indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals at the
secondary HO2S (Sensor 2) and the ECM/PCM. If
the screen indicates EXECUTING, keep driving until
a result comes on. If the screen indicates OUT OF
CONDITION, go to step 3 and recheck.
6. Turn the ignition switch to LOCK (0).
7. Replace the secondary HO2S (Sensor 2) (see page 11-221).
8. Turn the ignition switch to ON (II).
9. Reset the ECM/PCM with the HDS.
10. Do the ECM/PCM idle learn procedure (see page 11-310).
11. Start the engine, and let it idle without load (A/T in P or N, M/T in neutral) until the radiator fan comes
on. 12. Test-drive under these conditions:
 Engine coolant temperature (ECT SENSOR 1)above70°C(158°F)
 A/TinD,M/Tin4th
 Vehicle speed at 56 km/h (35 mph)
 Drive about 15 seconds
13. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the secondary HO2S (Sensor 2) and
theECM/PCM,thengotostep1.
Go to step 14.
14. Monitor the OBD STATUS for DTC P0139 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 13,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the secondary
HO2S(Sensor2)andtheECM/PCM,thengotostep
1. If the screen indicates EXECUTING, keep driving
until a result comes on. If the screen indicates OUT
OF CONDITION, go to step 11.
