P222E Code - Barometric Pressure Sensor 'B' Circuit Intermittent/Erratic

Quick Answer

The Powertrain Control Module (PCM) continuously monitors this sensor for concerns. Common causes include Faulty Barometric Pressure (BARO) sensor, Barometric Pressure (BARO) sensor harness is open or shorted, Barometric Pressure (BARO) sensor circuit poor electrical connection. 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 P222E Description

The Powertrain Control Module (PCM) continuously monitors this sensor for concerns. The test fails when the Barometric Pressure (BARO) Parameter Identification (PID) does not correlate with the Throttle Intake Pressure (TIP) or the Manifold Absolute Pressure (MAP) PIDs at ignition ON. This DTC sets when the PCM detects an out of range condition in the control circuit.

Frequently Asked Questions about P222E Code

1. What are common symptoms of OBDII code P222E (Barometric Pressure Sensor 'B' Circuit Intermittent/Erratic)?

- Common symptoms include rough idling, reduced engine performance, poor fuel efficiency, and possibly stalling.

2. What can cause the OBDII code P222E to trigger?

- The code P222E can be triggered by a faulty barometric pressure sensor, wiring problems, or issues with the engine control module (ECM).

3. How do I diagnose the cause of OBDII code P222E?

- To diagnose the cause of code P222E, you can start by checking the barometric pressure sensor and its wiring for any visible damage or corrosion. You may also need to perform voltage tests and resistance checks.

4. Can a dirty air filter cause OBDII code P222E?

- Yes, a dirty air filter can affect the barometric pressure sensor readings and potentially trigger code P222E. It's recommended to check and replace the air filter if needed.

5. Is it safe to continue driving with OBDII code P222E present?

- It is not recommended to continue driving with code P222E present, as it can lead to further engine issues and potential damage. It's best to address the underlying problem as soon as possible.

6. How can I repair OBDII code P222E at home?

- If you have some experience with automotive repairs, you can attempt to replace the barometric pressure sensor yourself. Make sure to follow the manufacturer's instructions and use the correct replacement part.

7. Can a loose gas cap trigger OBDII code P222E?

- A loose gas cap is unlikely to trigger code P222E specifically, as this code is related to the barometric pressure sensor circuit. However, it's always a good idea to ensure the gas cap is securely tightened to prevent other issues.

8. Will resetting the check engine light resolve OBDII code P222E?

- Simply resetting the check engine light will not resolve the underlying issue causing code P222E. It may temporarily turn off the light, but the problem will likely resurface until properly diagnosed and repaired.

9. How much does it typically cost to fix OBDII code P222E at a repair shop?

- The cost of fixing code P222E can vary depending on the cause of the issue, labor rates in your area, and the specific vehicle model. It's recommended to get a diagnostic from a trusted mechanic to determine the exact cost.

10. Can extreme weather conditions affect OBDII code P222E?

- Extreme weather conditions, such as temperature changes or high altitudes, can potentially affect the barometric pressure sensor readings and trigger code P222E. It's important to consider environmental factors during diagnosis and repairs.
