P222A OBD Error Code: Problem & Solutions
OBD Code P222A - Barometric Pressure Sensor “B” Circuit
The trouble code P222A can be explicated as
Barometric Pressure Sensor ‘B’ Circuit. This trouble code is generic, which
would mean that it can apply to all the vehicles which are equipped with the
OBD-II or the vehicles which are made since 1996 up to the present. The
specifications on the definition, the troubleshooting steps as well as repairs can
always vary from one vehicle make to another. This can happen because of a lot
of reasons and the mechanic should diagnose the specific cause for this code.

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.
What causes this problem with
the Barometric Pressure Sensor “B” Circuit?
- Faulty
BAP (Barometric Air pressure) sensor
- Malfunctioning
electrical connector
- There
can be inoperative wiring
- Some
issues related to the electrical short (internal or mechanical)
- The
electrical connection might be loose
- The
heat might cause damage
- Mechanical
malfunction may cause altered BAP readings
- Imperfect
engine control module
Replace/Repair These Parts To Fix Code P222A
- Manifold Absolute Pressure Sensor - A quirky manifold absolute pressure (MAP) sensor can upset fuel delivery as well as the ignition timing. Some performance problems can also arise like poor fuel economy, lack of engine power and sometimes the car won’t start at all. Find top quality manifold absolute pressure sensor online.
- Barometric Air Pressure Sensor - It is a type of engine management sensor which is generally found in a lot of vehicles. It measures the atmospheric pressure of the environment that the automobile is driving in. So if there are some faults in your barometric air pressure sensor, then you must purchase it online from us.
- Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
- Electronic Control Unit - The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
- Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
- Diagnostic Tool - Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!

Easy Diagnosis Of Engine Error OBD Code P222A
If
you want to easily diagnose this trouble code, then you must follow the steps
which are mentioned here as below:
Basic
Step #1
The
first and the foremost step is to 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.
Basic
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.
Basic 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.
Basic
Step #4
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 P222A Code
- Mass
air flow sensor related issues
- The
air filter might be blocked
- Quirks
in the powertrain control module
- Powertrain
control module software might have some issues
- Issues
related with the car wiring
