Is resistance within the specification?
YES
▶ Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
NO
▶ Check ECT sensor for contamination, deterioration, or damage. Substitute with a known-good ECT sensor and check for proper operation. If the problem is corrected, replace ECT sensor and then go to "Verification of Vehicle Repair" procedure.
