19. Turn the ignition switch to LOCK (0).
20. Drain the coolant (see page 10-8).
21. Remove ECT sensor 1 (see page 11-225) and ECT
sensor 2 (see page 11-225).
22. Allow the sensors to cool to ambient temperature.
23. Note the ambient temperature.
24. Connect ECT sensor 1 and ECT sensor 2 to their 2P connectors, but do not install them.
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.
Replace the sensor that differed more than
3 °C (5.4 °F) from the ambient temperature, then go
to step 27.
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 to ON (II).
28. Reset the ECM/PCM with the HDS.
29. Do the ECM/PCM idle learn procedure (see page
11-310).
30. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at ECT sensor 1, ECT sensor 2, and the
ECM/PCM, then go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
