P246F Ford Code - Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 4
Quick Answer
The P246F diagnostic trouble code (DTC) for Ford vehicles refers to the Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 4. Common causes include Faulty Exhaust Gas Temperature Sensor: The sensor itself may be malfunctioning and providing inaccurate readings, Wiring or Connection Issues: Damaged or corroded wiring or poor connections can disrupt the signal between the sensor and the ECM, Malfunctioning ECM: A problem with the engine control module can also trigger the P246F code. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P246F Ford Description
The P246F diagnostic trouble code (DTC) for Ford vehicles refers to the Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 4. This code indicates that there is an issue with the exhaust gas temperature sensor located in bank 1, sensor 4 of the vehicle. The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. This data is crucial for the engine control module (ECM) to optimize fuel delivery and emission control.
Common Causes of P246F Ford
- Faulty Exhaust Gas Temperature Sensor: The sensor itself may be malfunctioning and providing inaccurate readings.
- Wiring or Connection Issues: Damaged or corroded wiring or poor connections can disrupt the signal between the sensor and the ECM.
- Malfunctioning ECM: A problem with the engine control module can also trigger the P246F code.
- Exhaust System Problems: Issues with the exhaust system, such as leaks or restrictions, can affect the sensor's performance.
- Environmental Factors: Extreme temperatures or exposure to contaminants can impact the sensor's accuracy.
Symptoms of P246F Ford
- Check Engine Light: The most common symptom associated with the P246F DTC is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A faulty exhaust gas temperature sensor can lead to incorrect fuel delivery, resulting in decreased fuel efficiency.
- Engine Power Loss: The ECM may limit engine power to protect the system from potential damage due to inaccurate exhaust gas temperature readings.
- Increased Emissions: A malfunctioning exhaust gas temperature sensor can cause the vehicle to emit higher levels of harmful emissions.
- Rough Idle or Stalling: In some cases, the engine may experience rough idling or stalling due to the incorrect data provided by the sensor.
How to Fix P246F Ford
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the DTC and pinpoint the exact cause of the problem.
- Inspect the Sensor: Check the exhaust gas temperature sensor for any visible damage or signs of malfunction.
- Test Wiring and Connections: Inspect the wiring harness and connections for any damage or corrosion, and repair or replace as needed.
- Replace the Sensor: If the sensor is faulty, replace it with a new, OEM-quality part to ensure accurate readings.
- Clear DTCs and Test Drive: Clear the DTC from the ECM's memory, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P246F Ford
