Code P222D Description
The P222D diagnostic trouble code indicates that there is a high voltage condition in the Barometric Pressure Sensor 'B' circuit. The Barometric Pressure Sensor is responsible for measuring the atmospheric pressure outside the vehicle. This information is crucial for the engine control module (ECM) to calculate the correct air-fuel mixture for optimal engine performance.
Common Causes of P222D
- Faulty Barometric Pressure Sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to sensor connections
- Intake manifold leaks
- Faulty ECM
Symptoms of P222D
- Check engine light illuminated
- Reduced fuel efficiency
- Rough idling or stalling
- Engine misfires
- Reduced engine power
How to Fix P222D
- Scan the vehicle's computer for fault codes and confirm the P222D code.
- Inspect the Barometric Pressure Sensor 'B' circuit for any visible damage or corrosion.
- Test the sensor's output voltage using a multimeter to determine if it is functioning properly.
- Replace the Barometric Pressure Sensor if it is found to be faulty.
- Clear the fault codes, reset the ECM, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P222D
The cost of repairing a high Barometric Pressure Sensor 'B' circuit can vary depending on the specific cause of the issue. In general, the cost of replacing the Barometric Pressure Sensor itself can range from $50 to $200, while labor costs can range from $80 to $150 per hour. Additional costs may be incurred if wiring repairs or ECM replacement is necessary. It is recommended to consult with a trusted mechanic or auto repair shop for a more accurate estimate based on the specific vehicle make and model.
