13. Reset the ECM/PCM with the HDS.

14. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

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

Is DTC P2252 indicated?

YES -Check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM,
then go to step 1. If the connector and terminal fits are OK, go to step 17.

NO -Go to step 16.

16. Monitor the OBD STATUS for DTC P2252 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 15, go
to the INDICATED DTCS TROUBLESHOOTING.

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the A/F sensor
(Sensor 1) and the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, keep idling
until a result comes on.

17. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

18. Start the engine, and let it idle.

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

Is DTC P2252 indicated?

YES -If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE
ECM/PCM ), then go to step 18. If the ECM/PCM was substituted, go to step 1.

NO -Go to step 20.

20. Monitor the OBD STATUS for DTC P2252 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or
DTCs were indicated in step 19, go to the INDICATED DTCS TROUBLESHOOTING.

NO -If the screen indicates FAILED, go to step 1. If the ECM/PCM was updated, substitute a known-
good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 18. If the ECM/PCM was
substituted, go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result comes on.

DTC P2270: SECONDARY HO2S (SENSOR 2) CIRCUIT SIGNAL STUCK LEAN; DTC P2271:
SECONDARY HO2S (SENSOR 2) CIRCUIT SIGNAL STUCK RICH

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine, and let it idle without load (in Park or neutral) until the radiator fan comes on.

4. Test-drive under these conditions:



Engine coolant temperature (ECT SENSOR 1) above 158°F (70°C)



Vehicle speed at 35 mph (56 km/h) or more for at least 25 seconds

5. Monitor the OBD STATUS for DTC P2270 or P2271 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 6.

NO -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 OFF.

7. Replace the secondary HO2S (Sensor 2) (see A/F SENSOR REPLACEMENT ).

8. Turn the ignition switch ON (II).

9. Reset the ECM/PCM with the HDS.

10. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
