P0118 2000 Ford F150 Code - Engine Coolant Temperature Sensor Circuit High
Quick Answer
The P0118 code for a 2000 Ford F150 indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit being too high. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Damaged Wiring Harness: The wiring harness connecting the ECT sensor to the ECM may be damaged, leading to a high voltage signal, Corroded Connector: Corrosion or poor connection at the sensor's connector can cause erratic readings. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0118 2000 Ford F150 Description
The P0118 code for a 2000 Ford F150 indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit being too high. The ECT sensor is a crucial component that monitors the temperature of the engine coolant and sends this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing for optimal engine performance and efficiency. When the ECT sensor circuit reads a high voltage signal, it suggests that the engine coolant temperature is higher than expected, potentially leading to issues with engine performance, emissions, and overall vehicle operation.
Common Causes of P0118 2000 Ford F150
- Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Damaged Wiring Harness: The wiring harness connecting the ECT sensor to the ECM may be damaged, leading to a high voltage signal.
- Corroded Connector: Corrosion or poor connection at the sensor's connector can cause erratic readings.
- ECM Malfunction: In rare cases, a problem with the engine control module can trigger the P0118 code.
Symptoms of P0118 2000 Ford F150
- Check Engine Light: The most common symptom associated with the P0118 code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Overheating: A high engine coolant temperature reading can lead to actual engine overheating, which may result in steam coming from the engine bay or a noticeable increase in engine temperature.
- Poor Fuel Economy: Incorrect fuel delivery adjustments due to inaccurate temperature readings can lead to decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or stalling due to incorrect ignition timing caused by the high engine coolant temperature signal.
- Reduced Power: The vehicle may exhibit a lack of power or sluggish acceleration as a result of the ECM compensating for the false temperature readings.
How to Fix P0118 2000 Ford F150
- Diagnose the Issue: Use a scan tool to retrieve the trouble code and perform a visual inspection of the ECT sensor, wiring, and connector.
- Replace ECT Sensor: If the sensor is faulty, replace it with a new one following the manufacturer's guidelines.
- Check Wiring and Connector: Inspect the wiring harness for damage and the connector for corrosion, repairing or replacing as needed.
- Clear Codes: After completing the repair, clear the trouble codes from the ECM memory using a scan tool.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the engine operates correctly.
Cost to Fix P0118 2000 Ford F150
The typical repair costs for addressing a P0118 code on a 2000 Ford F150 can range from $100 to $300, including parts and labor. The cost of the ECT sensor itself is relatively affordable, usually ranging from $20 to $50, depending on the brand and quality. Labor costs can vary depending on the shop's hourly rates, with most auto repair shops charging between $80 and $150 per hour. It's advisable to check with local repair shops for more accurate pricing based on your specific location and vehicle.
