Code P0073 2017 Ford F150 Description
The P0073 diagnostic trouble code (DTC) for a 2017 Ford F150 indicates an issue with the Ambient Air Temperature Sensor Circuit 'A' being too high. This sensor is responsible for monitoring the temperature of the air surrounding the vehicle, providing crucial data to the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance. When the sensor reports a high voltage signal, it suggests that the ambient air temperature reading is abnormally elevated, which can lead to incorrect fuel mixture adjustments and potential drivability issues.
Common Causes of P0073 2017 Ford F150
- Faulty Ambient Air Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect temperature readings.
- Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the sensor circuit can disrupt the signal.
- ECM Malfunction: A problem with the engine control module can also lead to erroneous temperature readings.
- Environmental Factors: Extreme temperatures or exposure to moisture can affect the sensor's performance.
- Electrical Issues: Any electrical faults in the circuit can cause the sensor to report high voltage.
Symptoms of P0073 2017 Ford F150
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Inaccurate Temperature Readings: The vehicle's temperature display may show incorrect readings or fluctuate unexpectedly.
- Poor Fuel Efficiency: Due to incorrect fuel mixture adjustments, the vehicle may experience reduced fuel efficiency.
- Rough Idle: The engine may idle roughly or inconsistently due to incorrect temperature data affecting fuel delivery.
- Engine Performance Issues: The vehicle may exhibit decreased power or acceleration due to improper fuel mixture adjustments.
How to Fix P0073 2017 Ford F150
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the ambient air temperature sensor and its circuit.
- Test the Sensor: Check the sensor's resistance and voltage output to determine if it is functioning correctly.
- Inspect Wiring and Connectors: Ensure that the wiring and connectors in the sensor circuit are intact and free of damage.
- Replace the Sensor: If the sensor is faulty, replace it with a new one and reset the DTC.
- Clear Codes and Test Drive: Clear the DTC from the ECM memory and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0073 2017 Ford F150
The typical repair costs for addressing a P0073 code on a 2017 Ford F150 can range from $100 to $300, including parts and labor. However, it is important to note that specific diagnosis time and labor rates at auto repair shops can vary significantly based on factors such as location, vehicle make and model, and engine type.
