Error Code P222F: What It Means & What To Do?

<<See All OBD Codes

The trouble code P222F can be elucidated as Barometric Pressure Sensor A/B Correlation. This sensor is continuously monitored by the powertrain control module for the concerns. The test would fail when the barometric pressure (BARO) parameter identification (PID) would not correlate with the throttle intake pressure (TIP) or the manifold absolute pressure (MAP) PIDs at ignition ON. This error code would start triggering up when the powertrain control module would detect an out of range condition in the control circuit.

Want to learn something more about the P222F fault code? This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Barometric Pressure Sensor A/B Correlation?

• Defective or damaged BAP (Barometric Air pressure) sensor
• Quirks in the electrical connector
• There can be inoperative wiring
• There might be electrical short
• The electrical connection might be very loose
• Some issues related to the heat which might cause damage
• Mechanical malfunction causing altered BAP readings
• Engine control module might not be functioning properly

1. Engine Control Module - Most of the time it is difficult to intercept the ECM faults and thus must be checked for thoroughly. There can be a problem with the circuit or the software might have malfunctioned. Thus repair, replace or reprogram the component as per requirement.
2. Barometric Air Pressure Sensor - The BAP sensors are essential auto parts which are found on many modern engine management systems. They are simple in nature as they work by using the atmospheric pressure, but at the same time they can be difficult to test. If there are some problems in your BAP sensor or check engine light is illuminating, then you can always buy a new one from us online.
3. Powertrain Control Module - If the PCM is faulty, it can store wrong OBD codes and can lead to misdiagnosis. This can happen due to misinterpretation of data received from the various sensors and components which also affects the vehicle’s performance. Thus, replace it immediately.
4. Electronic Control Unit - If the ECU is at fault, it will not be able to read the boost converter temperatures correctly leading to underperformance. Thus, replace faulty ECU now!
5. Diagnostic Tool - Choose from our diagnostic tools collection that will come handy to detect and correct the OBD error code.

Common Symptoms

• There might be absence of engine power and performance (or limited)
• Engine misfiring
• Noises from car engine
• Fuel smell
• There might be a decrease in the fuel economy
• Throttle responsiveness might start diminishing

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• You must fix the defective MAP sensor
• Make sure to mend the faulty engine control module
• The malfunctioning mass airflow sensor should be repaired or replaced as per the need
• Carefully adjust the faults in the barometric air pressure sensor

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of pcm, ecm, barometric air pressure sensor, ambient air pressure, mass airflow sensor, air filter, body control module component and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

Here is the step 1

The initial step is to find the barometric air pressure sensor of your particular 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.).

Here is the step 2

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.

Here is the step 3

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.

Here is the step 4

Utilize 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 P222F Code

• There can be some faults in the mass air flow sensor
• Obstructed air filter
• Flaws in the powertrain control module software
• Negligence in the powertrain control module
• Wiring problems
