P206D Ford Code - Reductant Quality Sensor Circuit High
Quick Answer
The P206D Ford diagnostic trouble code indicates that there is a high circuit voltage detected in the reductant quality sensor circuit. Common causes include Faulty Reductant Quality Sensor: The sensor itself may be malfunctioning and sending incorrect signals to the vehicle's ECM, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the reductant quality sensor can cause high circuit voltage, ECM Malfunction: A malfunction in the engine control module (ECM) can also trigger this code by incorrectly interpreting sensor data. 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 P206D Ford Description
The P206D Ford diagnostic trouble code indicates that there is a high circuit voltage detected in the reductant quality sensor circuit. The reductant quality sensor is a crucial component in the vehicle's emissions control system, specifically in vehicles equipped with a selective catalytic reduction (SCR) system. This sensor is responsible for measuring the quality of the diesel exhaust fluid (DEF) that is injected into the SCR system to reduce harmful emissions.
Common Causes of P206D Ford
- Faulty Reductant Quality Sensor: The sensor itself may be malfunctioning and sending incorrect signals to the vehicle's ECM.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the reductant quality sensor can cause high circuit voltage.
- ECM Malfunction: A malfunction in the engine control module (ECM) can also trigger this code by incorrectly interpreting sensor data.
- Contaminated DEF: If the DEF fluid is contaminated, it can cause sensor readings to be skewed, leading to this code.
Symptoms of P206D Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Power: The vehicle may experience a reduction in power or acceleration due to the improper dosing of DEF.
- Poor Fuel Efficiency: A decrease in fuel efficiency may be noticed as a result of the emissions control system not functioning properly.
- Failed Emissions Test: If the issue is not addressed, it may cause the vehicle to fail emissions testing.
How to Fix P206D Ford
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform further testing to pinpoint the exact cause of the high circuit voltage.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test Sensor: Test the reductant quality sensor to ensure it is functioning properly. Replace if necessary.
- Check DEF Quality: Verify the quality of the DEF fluid being used in the vehicle to ensure it meets specifications.
- Clear Codes: After completing the repairs, clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P206D Ford
The cost of repairing a P206D Ford code can vary depending on the specific cause of the issue. On average, the repair cost for this type of problem can range from $200 to $500, including parts and labor. However, it's important to note that labor rates and part prices can vary significantly based on location, vehicle make and model, and the shop performing the repairs. It's recommended to get a detailed estimate from a trusted auto repair shop before proceeding with the repairs.
