P2228 Low Barometric Pressure Sensor

How severe is this DTC?

The severity will be moderately high here. When reading this, a certain sense of urgency should be applied to maintain effective engine operation. Whenever a fault can directly affect critical values such as air/fuel ratios and is actively present, you should not operate your vehicle to avoid engine damage. That said, if you’ve driven the vehicle since the fault became active, don’t worry too much, you’re probably fine. Key takeaway: if left unaddressed, this fault could lead to costly internal engine damage in the future.

What are some symptoms of the code?

Symptoms of a P2228 fault code may include:

  • Lack of engine power and performance (or limited)
  • Engine misfire
  • Abnormal engine noise(s)
  • Fuel smell
  • Decreased fuel economy
  • Reduced throttle response

What are some common causes of the code?

Causes of this P2228 code may include:

  • Faulty or damaged BAP (Barometric Air Pressure) sensor
  • Faulty or damaged electrical connector
  • Wiring issue (e.g., open circuit, short circuit, corrosion)
  • Electrical short (internal or mechanical)
  • Loose electrical connection
  • Heat damage
  • Mechanical malfunction causing altered BAP readings
  • ECM (Engine Control Module) problem

What are the troubleshooting steps for P2228?

Basic Step #1

Locate the BAP (Barometric Air Pressure) sensor on your specific vehicle. The location of these sensors has varied significantly in my experience, so finding the correct sensor should be of utmost importance. Once located, inspect the BAP sensor for any physical damage. Potential issues may depend on the location, so consider the sensor’s environment (i.e., high-heat areas, engine vibrations, exposure to weather/road debris, etc.).

Basic Step #2

Ensure the sensor connector itself is properly installed to maintain a good electrical connection. Especially if the sensor is located on the engine, it may be subject to vibrations that could loosen connections or cause physical damage.

NOTE: Remember to disconnect your battery before disconnecting sensors. Depending on the vehicle/system/sensor, you could cause damaging electrical spikes if you forget this step. That said, if you feel uncomfortable here or have limited basic electrical knowledge, I recommend towing/driving your vehicle to your trusted repair center.

Basic Step #3

Is something obstructing the sensor? This could cause false atmospheric pressure readings. Accurate readings are integral to optimal engine performance in these fuel management systems.

Basic Step #4

Using your multimeter and armed with the desired electrical values for the barometric air pressure sensor. You’ll need to disconnect the sensor connector itself to access the pins. Once you see the pins, follow manufacturer-specific diagnostic procedures with the desired values and compare. Anything outside the specified range will indicate a faulty sensor. Replace it following proper removal and reinstallation procedures.

P2231 O2 Sensor Signal Circuit Shorted to Heater Circuit, Bank 1 Sensor 1

A short-circuited oxygen sensor (HO2S) can cause engine malfunction and various driving issues. Code P2231 should be considered serious and requires immediate repair.

What are the symptoms of code P2231?

Symptoms associated with this code may include:

  • Decreased vehicle fuel efficiency.
  • Reduced engine performance.
  • Appearance of error codes related to misfires or air-fuel mixture being too lean or too rich.
  • Illumination of the “Check Engine” light.

What are the possible causes of code P2231?

Common causes of this code include:

  • A faulty oxygen sensor.
  • Damaged, burned, rubbed, broken, or disconnected wires or connectors.
  • Engine control module (PCM) programming error or a faulty PCM.

How to diagnose and fix code P2231?

To diagnose this code, you will need a diagnostic scanner, a digital multimeter (DVOM), and a reliable source of vehicle information.

  1. Retrieving codes and data: Connect the scanner to the vehicle’s diagnostic port and retrieve all stored codes and freeze frame data. Note this information, especially if the code is intermittent. Then, clear the codes and test the vehicle. Two scenarios are possible: either code P2231 reappears, or the PCM enters readiness mode.
  2. Visual inspection: Visually inspect the wiring and connectors related to the oxygen sensor (HO2S). Replace any damaged, burned, or cut wires.
  3. Sensor data analysis: If the code persists, start the engine and let it reach its normal operating temperature. Connect the scanner and observe the oxygen sensor data. In closed-loop mode, the pre-catalyst sensor voltage should fluctuate between 1 and 900 millivolts, while the post-catalyst sensors should stabilize at a fixed value.
  4. Checking with a multimeter: If the sensor shows battery voltage or no voltage, use a multimeter to measure the voltage directly at the HO2S connector. If the data remains abnormal, this indicates an internal short circuit in the sensor, which will need to be replaced.

Conclusion

In most cases, code P2231 can be resolved by replacing the faulty oxygen sensor. However, it is essential to perform a thorough diagnosis to confirm the exact cause of the problem before proceeding with any repairs.
