9. Allow ECT sensor 1 to cool to ambient temperature.

10. Note the ambient temperature.

11. Connect ECT sensor 1 to its 2P connector, but do not install the sensor on the engine.

YES -Replace ECT sensor 1 (see ECT SENSOR 1 REPLACEMENT ), then go to step 27.

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
ECT sensor 1, ECT sensor 2, and the ECM/PCM.

15. Start the engine, and let it idle 10 minutes.

16. Check ECT SENSOR 1 in the DATA LIST with the HDS.

Is about 115°F (46°C) or less indicated?

18. Check ECT SENSOR 2 in the DATA LIST with the HDS.

Is about 115°F (46°C) or less indicated?

YES -Replace ECT sensor 2 (see ECT SENSOR 1 REPLACEMENT ), then go to step 27.

NO -Go to step 19.

19. Turn the ignition switch OFF.

20. Drain the coolant (see COOLANT CHECK ).

21. Remove ECT sensor 1 (see ECT SENSOR 1 REPLACEMENT ) and ECT sensor 2 (see ECT

SENSOR 1 REPLACEMENT ).

22. Allow the sensors to cool to ambient temperature.

23. Note the ambient temperature.

24. Connect ECT sensor 1 to the 2P connector, and ECT sensor 2 to its 2P connector, but do not install them

on the engine.

25. Note the value of ECT SENSOR 1 and ECT SENSOR 2 quickly in the DATA LIST with the HDS.

26. Compare the value of ECT SENSOR 1 and the ambient temperature, and the value of ECT SENSOR 2

and the ambient temperature individually.

Does one of the sensors differ more than 5.4°F (3°C) from the ambient temperature?

YES -Replace the sensor that differed more than 5.4°F (3°C) from the ambient temperature, then go to
step 27.

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
ECT sensor 1, ECT sensor 2, and the ECM/PCM.

27. Turn the ignition switch ON (II).

28. Reset the ECM/PCM with the HDS.

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

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

Is DTC P1116 indicated?

YES -Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM,
then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

DTC P1128: MAP SENSOR SIGNAL LOWER THAN EXPECTED

NOTE:

1. Turn the ignition switch ON (II).

2. Check the MAP SENSOR in the DATA LIST with the HDS.

Is less than 54.1 kPa (16.0 in.Hg, 406 mmHg) or 1.61 V held for more than 5 seconds?

YES -Go to step 7.

NO -Go to step 3.

3. Clear the DTC with the HDS.

4. 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.

5. Test-drive under these conditions:



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



Engine speed between 1,400-5,400 rpm



A/T in D position (M/T in 3rd gear)



Vehicle speed accelerated from 16-31 mph (25-50 km/h) under half throttle

6. Monitor the OBD STATUS for DTC P1128 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 7.

NO -If the screen indicates PASSED, intermittent failure, the system is OK at this time. Check for poor
connections or loose terminals at the MAP sensor and the ECM/PCM. If the screen indicates NOT
COMPLETED, go to step 4 and recheck.

7. Turn the ignition switch OFF.

8. Replace the MAP sensor (see MAP SENSOR REPLACEMENT ).

9. Turn the ignition switch ON (II).

10. Reset the ECM/PCM with the HDS.

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

12. 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.

13. Test-drive under these conditions:



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



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review the general troubleshooting information (see
GENERAL TROUBLESHOOTING INFORMATION ).



Before you troubleshoot, check for poor connections or blockage at the
intake air duct.

NO -Go to step 15.

15. Monitor the OBD STATUS for DTC P1128 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 14, go
to the INDICATED DTCS TROUBLESHOOTING.

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the MAP sensor
and the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 12.
