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

  1. Start the engine, and let it idle for 5 minutes or more.
  2. Check ECT SENSOR 1 in the DATA LIST with the HDS. Is about 0°F (-18°C) or less indicated? YES -Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM. If the connections and the terminals are OK, replace ECT sensor 1 (see «ECT SENSOR 1 REPLACEMENT»(ref-355245-S32795880472010012100000) ), then go to step 8 . NO -Go to step 3.
  3. Turn the ignition switch to LOCK (0).
  4. Allow the engine to cool to 104°F (40°C) or less.
  5. Make sure the temperature difference between ECT SENSOR 1 and ECT SENSOR 2 is about 50°C (10°C) in the DATA LIST with the HDS.
  6. Start the engine, and let it idle until ECT SENSOR 1 goes up to about 158°C (70°C). Does ECT SENSOR 2 also show about 158°F (70°C)? YES -Go to step 7. 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.
  7. Check the thermostat (see «THERMOSTAT TEST»(ref-290817-S09372920842008072200000) ). Is the thermostat OK? YES -Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM. If the connections and the terminals are OK, replace ECT sensor 1 (see «ECT SENSOR 1 REPLACEMENT»(ref-355245-S32795880472010012100000) ), then go to step 8. NO -Replace the thermostat (see «THERMOSTAT REPLACEMENT»(ref-290817-S05262714552008072200000) ), then go to step 8.
  8. Turn the ignition switch to ON (II).
  9. Reset the ECM/PCM with the HDS.
  10. Turn the ignition switch to LOCK (0).
  11. Allow the engine to cool to 104°F(40°C) or less.
  12. Make sure the temperature difference between ECT SENSOR 1 and ECT SENSOR 2 is about 50°F (10°C) in the DATA LIST with the HDS.
  13. Start the engine, and let it idle until ECT SENSOR 1 goes up to about 158°F (70°C). Does ECT SENSOR 2 also show about 158°F (70°C)? YES -Go to step 1 and recheck. NO -Troubleshooting is complete.
