Engine Coolant Temperature Sensor Malfunction
on 2015 Kia Forte 1.8L I4 · FWD
What this code means
The PCM has detected a malfunction with the engine coolant temperature sensor. The sensor reading does not correlate with expected warm-up behavior or is providing erratic data.
Symptoms
- Check Engine Light
- Incorrect temperature gauge reading
- Poor fuel economy
- Fan may run continuously or not at all
- Hard cold starts
Common causes
- Faulty ECT sensor
- Corroded ECT sensor connector
- Wiring issue in ECT circuit
- Low coolant level exposing sensor
- Thermostat stuck open affecting readings
Diagnostic steps
- Compare ECT reading on scan tool with infrared thermometer measurement
- Test ECT sensor resistance at various temperatures
- Inspect ECT connector for corrosion
- Check coolant level
- Inspect wiring for damage
Repair notes
Replace the ECT sensor if its resistance does not match the temperature-resistance specification chart.
