Code P0221 MINI Description

The P0221 MINI diagnostic trouble code (DTC) refers to a problem with the Throttle Valve Potentiometer 2 Plausibility to Air Mass. This code indicates that there is a discrepancy between the position of the throttle valve potentiometer and the expected air mass entering the engine. The throttle valve potentiometer is a sensor that measures the position of the throttle valve, which controls the amount of air entering the engine. The air mass sensor measures the actual amount of air entering the engine. When the Engine Control Module (ECM) detects that the position of the throttle valve does not match the expected air mass, it triggers the P0221 code.

  3. Decreased fuel efficiency.
  4. Check Engine Light illuminated on the dashboard.
  5. Engine going into limp mode.

How to Fix P0221 MINI

  1. Begin by conducting a thorough inspection of the throttle valve potentiometer and air mass sensor to check for any visible damage or loose connections.
  2. Use a multimeter to test the resistance and voltage output of the throttle valve potentiometer to determine if it is functioning within specifications.
  3. Perform a similar test on the air mass sensor to ensure it is providing accurate readings.
  4. Check the wiring harness for any signs of damage or corrosion, and repair or replace any faulty wires.
  5. If necessary, replace the throttle valve potentiometer, air mass sensor, or ECM to address the root cause of the issue.

Cost to Fix P0221 MINI

The typical repair costs for addressing the P0221 MINI code can vary depending on the specific cause of the problem and the parts needed for the repair. In general, replacing the throttle valve potentiometer or air mass sensor can range from $150 to $300 each, not including labor costs. Labor rates at auto repair shops typically range from $80 to $150 per hour, so the total repair cost could amount to several hundred dollars. It's advisable to consult with a professional mechanic to get an accurate estimate based on the specific vehicle make and model, as well as the extent of the repairs needed.

When is the Code Detected?

An unexpected voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).
