Guide To P012D OBD Error Code Solutions

<<See All OBD Codes

Is there any issue related to powertrain control module? Or are you facing defects in the turbocharger/supercharger inlet pressure sensor? The general efficiency is reduced? If the answer to all these questions is a YES, then your vehicle is definitely facing OBD P012D error. If there is malfunctioning in the turbocharger/supercharger inlet pressure sensor, then the P012D error would start indicating

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 P012D trouble code.

The vehicle would be sent into the “limp home mode” due to this, 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 High Downstream Of Throttle Valve?

• Defects in the turbocharger/supercharger inlet pressure sensor
• Turbocharger/Supercharger Inlet Pressure Sensor harness can be opened or shorted
• Turbocharger/Supercharger Inlet Pressure Sensor circuit may start facing bad electrical connection

1. Powertrain Control Module - P012D code flashing? Get your Powertrain Control Module inspected from a mechanic.
2. Inlet Pressure Sensor - Do you remember when was the last time you got your car Inlet Pressure Sensor checked up? A damaged Inlet Pressure Sensor can cause a lot of issues like displaying P012D code.
3. Turbocharger - The P012D code can also arise due to some issues in Turbocharger. So, it is advised to replace them as soon as possible.
4. Supercharger - Supercharger is an important car part which should never be neglected. May be there is some fault in it due to which P012D code may start flashing.
5. Throttle Valve - Common cause behind this P012D error code can be some fault in Throttle Valve. So, it will be a good decision to replace them now.
6. Intake Manifold - Are you facing some faults in your Intake Manifold? Don’t worry and get them replaced or else P012D code can turn up.

It is very important to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P004D here:

Common Symptoms

• Your vehicle can start to enter limp mode
• Noises may start coming from car engine
• Bad overall performance
• Engine may experience misfiring
• The issue of stalling may arise
• Decrease in the fuel mileage

Have a look at some ways with which you can correct the P012D code:

• The damaged turbo/supercharger inlet pressure sensor should be replaced
• There can be some with the wiring harness, which can cause problems. So, you must get it repaired or replaced
• If your car air filter system 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 and many more. Now all your problems would vanish within no time.

• Make sure that you visually inspect the TCIP and surroundings. 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.
• Due to this 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’s 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 auto 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 P012D Code

• Inlet pressure sensor may experience some failure
• There can be some faults in the powertrain control module
• Car relay wiring issue may arise
