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 21.

NO -Go to step 20.

20. Monitor the OBD STATUS for DTC P1157 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 19, 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.

21. 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 ).

22. Start the engine, and let it idle.

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

Is DTC P1157 indicated?

YES -If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE
ECM/PCM ), then go to step 22. If the ECM/PCM was substituted, go to step 1.

NO -Go to step 24.

24. Monitor the OBD STATUS for DTC P1157 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 23, 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 22. If the ECM/PCM was
substituted, go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result comes on.

connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM. If the screen indicates
EXECUTING, keep idling until a result comes on. If the screen indicates OUT OF CONDITION, go to
step 3 and recheck.

5. Turn the ignition switch OFF.

6. Replace the A/F sensor (Sensor 1) (see A/F SENSOR REPLACEMENT ).

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

10. 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.

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

Is DTC P1172 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.

NO -Go to step 12.

12. Monitor the OBD STATUS for DTC P1172 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 11, 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 EXECUTING, keep idling until a
