P2220 Ford Code - NOx Sensor Heater Control Circuit High Bank 2
Quick Answer
The P2220 code for Ford vehicles indicates a problem with the NOx (nitrogen oxide) sensor heater control circuit in Bank 2. Common causes include Faulty NOx Sensor: A malfunctioning NOx sensor itself could be the root cause of the P2220 code, Wiring Issues: Damaged or corroded wiring in the heater control circuit can disrupt the flow of current and trigger the code, Blown Fuse: A blown fuse in the NOx sensor heater circuit can prevent the heater from functioning properly. 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 P2220 Ford Description
The P2220 code for Ford vehicles indicates a problem with the NOx (nitrogen oxide) sensor heater control circuit in Bank 2. The NOx sensor is a crucial component in modern vehicles that helps monitor and reduce harmful emissions produced by the engine. The sensor measures the levels of nitrogen oxide in the exhaust gases and sends this data to the engine control module (ECM) to optimize fuel mixture and reduce emissions.
Common Causes of P2220 Ford
- Faulty NOx Sensor: A malfunctioning NOx sensor itself could be the root cause of the P2220 code.
- Wiring Issues: Damaged or corroded wiring in the heater control circuit can disrupt the flow of current and trigger the code.
- Blown Fuse: A blown fuse in the NOx sensor heater circuit can prevent the heater from functioning properly.
- ECM Malfunction: A problem with the engine control module (ECM) can also lead to issues with the NOx sensor heater control circuit.
Symptoms of P2220 Ford
- Check Engine Light: The most common symptom associated with the P2220 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A faulty NOx sensor heater control circuit can lead to inefficient fuel combustion, resulting in decreased fuel efficiency.
- Failed Emissions Test: The vehicle may not pass emissions tests due to increased nitrogen oxide emissions caused by the malfunctioning NOx sensor.
- Rough Idle: The engine may experience rough idling or hesitation during acceleration due to improper fuel mixture adjustments based on inaccurate sensor readings.
How to Fix P2220 Ford
- Diagnostic Scan: Begin by using an OBD-II scanner to retrieve the specific code and identify the underlying issue with the NOx sensor heater control circuit.
- Inspect Wiring: Check the wiring harness connected to the NOx sensor for any signs of damage or corrosion. Repair or replace any faulty wiring as needed.
- Test Heater Element: Verify the functionality of the NOx sensor heater element to ensure it is drawing the correct amount of current. Replace the heater element if it is defective.
- Check Fuse: Inspect the fuse related to the NOx sensor heater circuit and replace it if necessary.
- Clear Codes: After making the necessary repairs, clear the diagnostic trouble codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2220 Ford
The cost of repairing a P2220 code for a Ford vehicle can vary depending on the specific model and the extent of the issue. Typically, the parts required for this repair, such as a new NOx sensor heater element, wiring harness, or fuse, can range from $100 to $300. The labor costs associated with diagnosing and fixing the problem may add another $100 to $300 to the total bill. Overall, the total repair cost for addressing a P2220 code could range from $200 to $600, depending on the shop's hourly labor rates and any additional components that may need replacement. It's recommended to consult with a trusted mechanic or dealership to get a more accurate estimate based on your vehicle's make and model.
