Is ECT sensor normal?
YES
ECT sensor is OK.
Possibility of defective ECM.Temporarily test with a new ECM and check for proper operation.
If problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure.
NO
Test with a new ECT sensor and check for proper operation.If problem is corrected, replace it.
And go to "Verification of Vehicle Repair" procedure.
