P012A OBD Error Code: Problem & Solutions
OBD Code P012A - Turbocharger/Supercharger Inlet Pressure Sensor Circuit (Downstream of throttle valve)
The
OBD-II Code powertrain control module failure can be defined as a
turbocharger/supercharger inlet pressure sensor circuit.
The
powertrain control module or the PCM keeps an eye on the
turbocharger/supercharger inlet pressure sensor circuit signal. The P012A OBD
code is set in by the powertrain control module when the
turbocharger/supercharger inlet pressure sensor signal is out of factory
specifications.

It is
the turbocharger/supercharger inlet pressure sensor which would tell the engine
control module how much air is being forced into the engine. If the PCM detects
that there is some incorrect signal from the sensor, then it will set P012A
fault code. Now due to this the vehicle would be sent into the “limp home
mode”, which would limit the amount of power out of the engine and would
protect the other components from getting damaged.
What causes this problem with the Turbocharger/Supercharger
Inlet Pressure Sensor Circuit (Downstream of throttle valve)?

How To Correct P012A Turbocharger/Supercharger Inlet Pressure Sensor Circuit (Downstream of throttle valve)
Have a look at some
ways with which you can correct the P012A code:
- The first and the
foremost thing which you should do is to replace the turbo/supercharger inlet
pressure sensor
- There can be some issue with the wiring harness, which can cause
problems. So, you must get it repaired or replaced
- If your car air filter is clogged, then the best idea would be to
replace it with a brand new one
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 air intake filter, fuel pressure sensor, relay wiring and many more. Now all your problems would vanish within no time.
Easy Diagnosis Of Engine Error OBD Code P012A
The
TCIP and surroundings should be visually inspected. Since we are aware about
the nature of these fault codes, it makes us think that there is surely some
sort of physical problem causing this issue. That is the reason why you must
check the harness thoroughly because the harnesses for these sensors typically
run along areas where extremely high temperatures are present. You must refer
to Downstream of Throttle valve if you want to locate which sensor circuit is malfunctioning. Downstream
means after the throttle valve or the side closer towards the intake manifold.
The throttle valve is generally mounted to the intake manifold. Once the TCIP has
been located, then the wires coming out of it should be followed and you must
inspect frayed/chafed/cut wires that may be causing an issue. The location of
the sensor depends on your vehicle make and model and you must have enough
access to the sensor’s connector. You can always disconnect it and inspect the
pins for corrosion.
The
use of a circuit would totally depend on the make and model of your vehicle.
Locate the fuse boxes just about anywhere in the car. Some of the good places
where it can be placed are under the dash, behind the glove box, under the
hood, under a seat etc. Carefully locate the fuse and make sure it fits within
the slot tightly and make sure that it doesn’t blow.
The
other step is to check your car air filter. There can be some signs of clogging
or dirtiness, so you must visually inspect your car air filter. You must
replace your car air filter if it is clogged or showing any signs of damage.
This is surely a cost-efficient way because air filters are inexpensive and
easy to replace. You can always check to see if your car air filter can be
cleaned; in that case there would be no need to replace it. Cleaning it would
be a better idea than replacing the entire assembly.
If
you have checked out almost everything and still not able to find a
malfunction, then you must check the circuit itself. This may include
disconnect the ECM or PCM electrical connector so make sure your battery is
connected. You can always perform some basic electrical tests on the circuit.
This can be done by checking the continuity, check for short to ground, power
and more. If there is any kind of open or short, then it would indicate that
there is some problem and you will have to get it repaired.
Common Mistakes When Diagnosing the P012A Code
- Inlet
pressure sensor can start failure
- There can be some failure in the powertrain control module
- Issue
of wiring can arise
