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 Kia Spectra I рестайлинг

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.

Diagnostic Aids

Malfunction code will set if 600 seconds has passed sense engine was started, Engine Coolant Temperature (ECT) sensor input to Engine Control Module (ECM) is more than 280°F (138°C), or if ECT sensor input to ECM is less than -36°F (-38°C). Also if thermostat stuck open. Check for following possible problems

1. Open or short between ECT sensor and ECM.
2. Short between ECT sensor wires.
3. Theorematic stuck open.
4. Poor connections between ECT sensor and ECM.
5. Misplace, loose or corroded terminals.
6. Contaminated or deteriorated ECT sensor.
7. Faulty ECT sensor.
