This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal from a sensor that measures air pressure outside the car, and the signal is too high. It's like when a thermometer says it's way hotter than it really is.
The P222D code is triggered when the powertrain control module (PCM) detects a high voltage signal from the Barometric Pressure Sensor B, indicating that the sensor is reading higher than expected atmospheric pressure.
The Barometric Pressure Sensor B is responsible for measuring the atmospheric pressure outside the vehicle. This information is used by the PCM to adjust engine parameters for optimal performance. A high circuit signal suggests that the sensor is reporting a pressure level that is higher than the actual atmospheric pressure, which could be due to a sensor fault, wiring issues, or a PCM problem.
• Check Engine Light is on
• Poor engine performance
• Increased fuel consumption
• Faulty Barometric Pressure Sensor B
• Wiring issues such as short circuits or open circuits
• Faulty PCM (Powertrain Control Module)
PCM: Powertrain Control Module, the vehicle's computer that manages engine and transmission functions.
OBD-II: On-Board Diagnostics, a system that monitors vehicle performance and emissions.
• Use an OBD-II scanner to confirm the P222D code.
• Inspect the wiring and connectors for the Barometric Pressure Sensor B.
• Test the sensor using a multimeter to check for proper voltage output.
• Replace the Barometric Pressure Sensor B if faulty.
• Repair or replace any damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II Scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain the vehicle's sensors and wiring.
• Avoid exposure to extreme weather conditions when possible.
• Keep the vehicle's software up to date.
Sensor Issue
• If the Check Engine Light is on, have the vehicle inspected as soon as possible.
• Avoid driving in extreme weather conditions until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on sensors and related components.
This code has been associated with sensor failures and wiring issues in various vehicle models.
Moderate – While the vehicle may still be drivable, it is important to address this issue to prevent further engine performance problems.
Ignoring this code could lead to increased emissions and potential damage to the engine.
• Vehicle at operating temperature
• Stable atmospheric conditions
The Barometric Pressure Sensor B is typically located near the intake manifold or integrated into the PCM.
Q: Can I drive with a P222D code?
A: While the vehicle may still be drivable, it's best to have it inspected and repaired to avoid potential engine performance issues.
Q: How does a barometric pressure sensor work?
A: It measures the atmospheric pressure outside the vehicle to help the engine adjust for optimal performance.
