Code P0071 2019 Ford F150 Description
The P0071 diagnostic trouble code (DTC) for a 2019 Ford F150 refers to the Ambient Air Temperature Sensor Circuit 'A' Range/Performance. This code indicates that there is a problem with the ambient air temperature sensor or its circuit. The ambient air temperature sensor is responsible for measuring the outside air temperature and sending this information to the engine control module (ECM). The ECM uses this data to adjust various engine functions, such as fuel injection timing and air-fuel mixture, based on the outside temperature.
Common Causes of P0071 2019 Ford F150
- Faulty Ambient Air Temperature Sensor: The sensor itself may be malfunctioning, leading to inaccurate temperature readings.
- Damaged Wiring or Connectors: The wiring or connectors in the ambient air temperature sensor circuit may be damaged or corroded, causing a poor connection.
- ECM Software Issue: An issue with the engine control module software may prevent it from properly interpreting the data from the ambient air temperature sensor.
- Environmental Factors: Exposure to extreme temperatures or moisture can damage the ambient air temperature sensor or its circuit.
- Electrical Short: An electrical short in the ambient air temperature sensor circuit can trigger the P0071 code.
Symptoms of P0071 2019 Ford F150
- Check Engine Light: The most common symptom associated with the P0071 code is the illumination of the check engine light on the vehicle's dashboard.
- Inaccurate Outside Temperature Reading: The vehicle's temperature display may show incorrect outside temperature readings.
- Poor Fuel Efficiency: A faulty ambient air temperature sensor can lead to decreased fuel efficiency as the engine may not be properly adjusted based on the outside temperature.
- Rough Idle: The engine may experience rough idling or hesitation due to incorrect temperature readings affecting fuel injection timing.
- Emissions Issues: The vehicle may fail emissions tests due to incorrect engine adjustments based on inaccurate outside temperature readings.
How to Fix P0071 2019 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.
- Replace the Ambient Air Temperature Sensor: If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Check Wiring and Connectors: Inspect the wiring and connectors in the ambient air temperature sensor circuit for any damage or corrosion. Repair or replace as necessary.
- Clear DTCs: After completing the repair, clear the DTCs from the ECM memory using a scan tool to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the ambient air temperature sensor is now functioning correctly and that the check engine light does not reappear.
Cost to Fix P0071 2019 Ford F150
The typical repair costs for addressing the P0071 code on a 2019 Ford F150 can vary depending on the specific cause of the issue. In general, the cost of replacing the ambient air temperature sensor can range from $50 to $150, while the labor cost for this repair can be between $80 and $150 per hour. Additional costs may include diagnostic time, wiring repairs, or connector replacements if needed. It is advisable to check with local auto repair shops to get a more accurate estimate based on your location and vehicle specifics.
