Details of the Ford p0117 OBD Code
Ford code P0117 relates to the engine coolant temperature sensor circuit having a low input.
OBD code P0117 for Ford vehicles indicates a fault 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) that is outside of the normal operating range.
The ECM uses this signal to determine the engine coolant temperature, which is crucial for proper fuel delivery and ignition timing.
When the ECM detects a signal that is too low or too high, it triggers the P0117 fault code.
This code can lead to drivability issues and poor engine performance.
Mechanic’s Tech Notes
Detailed information on diagnosing and repairing fault code P0117 in Ford vehicles.
OBDII code P0117 on a Ford typically indicates an issue with the Engine Coolant Temperature (ECT) sensor circuit.
To diagnose, use a multimeter to test the ECT sensor’s resistance and compare it to specifications.
Check the sensor’s wiring for any breaks, shorts, or corrosion.
Ensure the sensor connector is securely attached and inspect for any signs of damage.
Scan tools can help monitor live data to see if the ECT sensor readings are accurate.
If all checks out, consider replacing the ECT sensor itself.
Remember to clear the code after repairs and test drive to confirm the issue is resolved.
