DTC P0117 & DTC P0118 Kia Optima I рестайлинг

Code Definition

1. DTC P0117: Engine Coolant Temperature Circuit Low Input
2. DTC P0118: Engine Coolant Temperature Circuit High Input

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

Engine Control Module (ECM) continuously monitors input from Engine Coolant Temperature (ECT) sensor. ECM will set malfunction code if input is more or less than range of expected values for current engine operating conditions. And when after engine start-up, elapsed time before feedback operation is initiated is too long (engine coolant temperature sensor input is insufficient for close loop operation). Check for following possible problems

1. Open or short between ECT sensor and ECM.
2. Misplaced, loose or corroded ECT sensor and ECM connectors terminals.
3. Short between ECT sensor and ECM.
4. Short between ECT sensor wires.
5. Faulty ECT sensor.
