Secondary HO2S (Sensor 2)

Circuit Low Voltage
(2002-2004 models)

1. Reset the ECM/PCM (see page 11-4).

2. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on.

3. Check the secondary HO2S (Sensor 2) output

voltage with a scan tool or the HDS.

Go to step 4.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
C401 (located under middle of dash), C101 (located
under middle of dash), the secondary HO2S
(Sensor 2), and the ECM/PCM.

4. Turn the ignition switch OFF.

5. Disconnect the secondary HO2S (Sensor 2) 4P

connector.

6. Start the engine.

7. Check the secondary HO2S (Sensor 2) output

voltage with a scan tool or the HDS.

Go to step 8.

Replace the secondary HO2S (Sensor 2)

(see page 11-279).

8. Turn the ignition switch OFF.

9. Disconnect ECM/PCM connector A (32P).

10. Check for continuity between secondary HO2S

(Sensor 2) 4P connector terminal No. 2 and body
ground.

Repair short in the wire between the ECM/

PCM (E2) and the secondary HO2S (Sensor 2).

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).

Terminal side of male terminals

Does the voltage stay at 0.3 V or less?

Is ther e continuity?

(2005-2006 models)

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.

4. Check the HO2S S2 in the DATA LIST with the HDS.

Go to step 5.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
the secondary HO2S (Sensor 2) and the ECM/
PCM.

5. Turn the ignition switch OFF.

6. Disconnect the secondary HO2S (Sensor 2) 4P

connector.

7. Turn the ignition switch ON (II).

8. Check the HO2S S2 in the DATA LIST with the HDS.

Go to step 9.

Go to step 13.

9. Turn the ignition switch OFF.

10. Jump the SCS line with the HDS.

11. Disconnect ECM/PCM connector E (31P).

12. Check for continuity between secondary HO2S

(Sensor 2) 4P connector terminal No. 2 and body
ground.

Repair short in the wire between the ECM/

PCM (E20) and the secondary HO2S (Sensor 2),
then go to step 15.

Go to step 23.

13. Turn the ignition switch OFF.

14. Replace the secondary HO2S (Sensor 2) (see page

11-279).

15. Reconnect all connectors.

16. Turn the ignition switch ON (II).

17. Reset the ECM/PCM with the HDS.

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

11-349).

19. 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.

DTC Troubleshooting (cont’d)

20. Test-drive under these conditions:

• Engine coolant temperature above 176 °F (80 °C)
• A/T in D position (M/T in 4th gear)
• Engine speed at 1,500

3,000 rpm

• Drive 1 minute or more

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

If DTC P0137 is indicated, check for poor

connections or loose terminals at the secondary
HO2S (Sensor 2) 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.

Go to step 22.

22. Monitor the OBD STATUS for DTC P0137 in the

DTCs MENU with the HDS.

Troubleshooting is complete.

If the screen indicates FAILED, check for poor

connections or loose terminals at the secondary
HO2S (Sensor 2) and the ECM/PCM, then go to
step 1. If the screen indicates EXECUTING, keep
driving until a result comes on. If the screen
indicates OUT OF CONDITION, go to step 19 and
recheck.

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

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

24. 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.

25. Test-drive under these conditions:

• Engine coolant temperature above 176 °F (80 °C)
• A/T in D position (M/T in 4th gear)
• Engine speed at 1,500

3,000 rpm

• Drive 1 minute or more

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

If DTC P0137 is indicated, check for poor

connections or loose terminals at the secondary
HO2S (Sensor 2) and the ECM/PCM, then go 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).
