1. Turn the ignition switch to ON (II).
2. Check ECT SENSOR 1 in the DATA LIST with the HDS. Is about -40°F (-40°C) or less, or 4.90 V or more indicated? YES -Go to step 3. NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at ECT sensor 1 and the PCM.
3. Turn the ignition switch to LOCK (0).
4. Disconnect the ECT sensor 1 2P connector.
5. Connect ECT sensor 1 2P connector terminals No. 1 and No. 2 with a jumper wire.
6. Turn the ignition switch to ON (II).
7. Check ECT SENSOR 1 in the DATA LIST with the HDS. Is about -40°F (-40°C) or less, or 4.90 V or more indicated? YES -Go to step 8. NO -Go to step 20 .
8. Turn the ignition switch to LOCK (0).
9. Remove the jumper wire from the ECT sensor 1 2P connector.
10. Turn the ignition switch to ON (II).
11. Measure the voltage between ECT sensor 1 2P connector terminal No. 1 and body ground. Is there about 5 V? YES -Go to step 12. NO -Go to step 16 .
12. Turn the ignition switch to LOCK (0).
13. Jump the SCS line with the HDS.
14. Disconnect PCM connector B (49P).
15. Check for continuity between PCM connector terminal B34 and ECT sensor 1 2P connector terminal No. 2. Is there continuity? YES -Go to step 27 . NO -Repair an open in the wire between the PCM (B34) and ECT sensor 1, then go to step 22 .
16. Turn the ignition switch to LOCK (0).
17. Jump the SCS line with the HDS.
18. Disconnect PCM connector B (49P).
19. Check for continuity between PCM connector terminal B24 and ECT sensor 1 2P connector terminal No. 1. Is there continuity? YES -Go to step 27 . NO -Repair an open in the wire between the PCM (B24) and ECT sensor 1, then go to step 22 .
20. Turn the ignition switch to LOCK (0).
21. Replace ECT sensor 1 (see «ECT SENSOR 1 REPLACEMENT»(ref-513153-S10450075522012110700000) ).
22. Reconnect all connectors.
23. Turn the ignition switch to ON (II).
24. Reset the PCM with the HDS.
25. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-513173-S16164063582012110700000) ).
26. Check for Pending or Confirmed DTCs with the HDS. Is DTC P0118 indicated? YES -Check for poor connections or loose terminals at ECT sensor 1 and the PCM, then go to step 1 . NO -Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-513153-S06499438282012110700000) .
27. Reconnect all connectors.
28. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-513153-S08553155092012110700000) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-513169-S18138486322012110700000) ).
29. Check for Pending or Confirmed DTCs with the HDS. Is DTC P0118 indicated? YES -Check for poor connections or loose terminals at ECT sensor 1 and the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-513169-S18138486322012110700000) ), then recheck. If the PCM was substituted, go to step 1 . NO -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-513153-S08243124262012110700000) ). If any other Pending or Confirmed DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-513153-S06499438282012110700000) .
