P2228 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2228 can be described as Barometric Pressure Sensor "A" Circuit Low. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

It is the powertrain control module which would examine the barometric pressure sensor. This trouble code would be set by the PCM when the barometric pressure sensor circuit would not be as per the parameters set by the manufacturer.

What causes this problem with the Barometric Pressure Sensor "A" Circuit Low?

• BAP (Barometric Air pressure) sensor might be damaged
• Quirks in the electrical connector
• Some wiring issues might exist
• Electrical short
• Loose electrical connection
• Damage due to heat
• Mechanical malfunction causing altered BAP readings
• Defective engine control module issue

1. Electronic Control Unit - ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
2. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
3. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
4. Barometric Air Pressure Sensor - The fuel and timing conditions are determined with the help of readings from the BAP sensor. So, if the signal is compromised for any reason, then the computer calculations will be thrown off. This would give rise to sluggish acceleration, lack of power, and also misfires in more severe cases. So, it is very important to replace the barometric air pressure sensor with us at equitable prices.

Do you wish to diagnose P2228 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

Firstly, you should find the barometric air pressure sensor of your specific vehicle. It is very important to locate this sensor carefully. Now once it has been located correctly, then the BAP sensor should be checked for any physical damage. Possible problems can depend on the location so take sensor's surroundings into consideration (i.e. High heat areas, engine vibrations, exposed to elements/road debris, etc.). It is very important to make sure the connector on the sensor itself is seated properly so that the electrical connection is good. Especially if the sensor is situated on the engine, then it might be subject to vibrations which can cause connections to become loose or might sometimes physically damage them. Just keep in mind to disconnect your battery before the sensors are disconnected.

It all depends upon the vehicle/system/sensor as it can cause damaging electrical spikes if you forget this step. You can always /drive your vehicle to your reputable repair facility if you are getting confused. Did you find out anything obstructing the sensor? It might be causing false atmospheric pressure readings. Correct readings are integral for optimal engine performance in these fuel management systems. Use multimeter and armed with desired electrical values for the barometric air pressure sensor. The connector from the sensor should be disconnected itself to gain access to the pins. Once you are able to see the pins, then follow manufacturer specific diagnostic procedures with desired values and compare them. Anything out of the particular range will indicate a faulty sensor. You should restore it following proper re+re procedures.

Common Mistakes When Diagnosing The P2228 Code

• The powertrain control module might start failing
• Failure in the software of the powertrain control module
• Non observance of the mass air flow sensor
• Plugged air filter
• Some issues with the car wiring
