Code P0059 2019 Ford F150 Description

The diagnostic trouble code P0059 for a 2019 Ford F150 refers to an issue with the heated oxygen sensor (HO2S) heater resistance for Bank 2 Sensor 1. The HO2S is a crucial component of the vehicle's emissions control system, responsible for monitoring the oxygen levels in the exhaust gases to ensure optimal fuel efficiency and reduce harmful emissions. The heater element within the sensor is designed to reach and maintain a specific temperature to accurately measure oxygen levels.

  2. Decreased Fuel Efficiency: A malfunctioning HO2S can lead to incorrect fuel mixture readings, resulting in decreased fuel efficiency.
  3. Rough Idle: The engine may experience a rough idle or hesitation during acceleration due to inaccurate oxygen level readings.
  4. Poor Engine Performance: The vehicle may exhibit reduced power and overall poor engine performance.
  5. Increased Emissions: Faulty oxygen sensor readings can lead to increased emissions output, potentially causing the vehicle to fail emissions tests.

How to Fix P0059 2019 Ford F150

  1. Diagnostic Testing: Use a scan tool to retrieve the trouble code and perform diagnostic testing to pinpoint the exact cause of the issue.
  2. Replace Oxygen Sensor: If the sensor is determined to be faulty, it should be replaced with a new, OEM-quality sensor.
  3. Check Wiring: Inspect the wiring harness for any damage or corrosion and repair or replace as necessary.
  4. Check Fuse: Verify the condition of the fuse related to the HO2S heater circuit and replace if needed.
  5. ECM Reprogramming: In cases where the ECM is suspected to be the issue, reprogramming or replacing the module may be necessary.

Cost to Fix P0059 2019 Ford F150

The cost estimate for repairing a HO2S heater resistance issue can vary depending on the specific cause of the problem and the labor rates at the auto repair shop. On average, replacing an oxygen sensor can cost between $200 and $300, including parts and labor. Additional costs may be incurred if wiring repairs or ECM reprogramming are necessary. It's recommended to consult with a trusted mechanic or dealership to get an accurate estimate based on the individual circumstances of the vehicle.
