Details of the Ford p0118 OBD Code
Code P0118 in Ford vehicles indicates a high engine coolant temperature sensor signal.
Ford OBD code P0118 indicates a problem with the Engine Coolant Temperature (ECT) sensor circuit.
This code is triggered when the ECT sensor sends a signal to the Engine Control Module (ECM) indicating that the engine coolant temperature is too high or too low for the current operating conditions.
The ECM uses this information to adjust fuel delivery and ignition timing for optimal engine performance.
If the ECT sensor or its circuit is faulty, it can lead to drivability issues and poor fuel economy.
Mechanic’s Tech Notes
For Ford code P0118, check the engine coolant temperature sensor circuit for high voltage.
To diagnose and fix OBDII code P0118 on a Ford, start by checking the engine coolant temperature (ECT) sensor circuit.
Use a voltmeter to test the ECT sensor’s resistance and compare it to specifications.
Inspect the wiring harness and connectors for any damage or corrosion.
Ensure the ECT sensor is securely connected and functioning correctly.
If no issues are found, consider replacing the ECT sensor itself.
Additionally, using a scan tool, monitor live data to see if the ECT sensor readings are within the expected range.
If necessary, perform a relearn procedure for the ECT sensor.
