DTC P0116: Engine Coolant Temperature Circuit Range/Performance Malfunction, DTC P0117: Engine Coolant Temperature Sensor Circuit Low Input, DTC P0118: Engine Coolant Temperature Sensor Circuit High Input & DTC P0128: Engine Coolant Thermostat Stuck Open: Notes

NOTE: Before performing any DIAGNOSTIC TEST, refer toWARNINGS, CAUTIONS and NOTES in DIAGNOSTIC TESTS .

NOTE: Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
