P012C - OBD Trouble Code

<<See All OBD Codes

Always maintain your turbocharger/supercharger inlet pressure sensor, throttle valve as well as powertrain control module properly or else the OBD Code P012C could start appearing. This code generally applies to OBD-II vehicles. A lot of vehicles may face this trouble code like Volvo, Ford, Audi, Hyundai etc.

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 P012C trouble code.

Because of 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 Low Downstream Of Throttle Valve?

• Faults 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 experiencing poor electrical connection

1. Powertrain Control Module - OBD Error Code P012C can also be due to faulty Powertrain Control Module. It’s better to get the faulty Powertrain Control Module replaced as soon as possible.
2. Inlet Pressure Sensor - Did your mechanic just found out that there is some fault in the Inlet Pressure Sensor? Buy top notch Inlet Pressure Sensor from us at economical prices.
3. Turbocharger - P012C code can display due to some defects in the Turbocharger. So, it is very important to replace the Turbocharger with us at equitable prices.
4. Supercharger - Defective Supercharger can cause a lot of difficulties, so why not get it replaced at time?
5. Throttle Valve - Do you remember when was the last time you got your car Throttle Valve replaced? A faulty Throttle Valve can cause a lot of issues like displaying P012C code.
6. Intake Manifold - There can be some issues with the Intake Manifold due to which you may see P012C code appearing over and over again. Visit us to buy best quality Intake Manifold online.

We care for our customers and that’s why we can totally understand your problem. That’s the reason why we have listed out some major symptoms behind the flashing up of OBD Code P012C. They are mentioned here as follows:

Common Symptoms

• Vehicle may start entering limp mode
• Noises can start coming from car engine
• Poor overall performance
• The issue of engine misfiring can arise
• Problem of stalling
• The overall fuel mileage can start decreasing

Here are some ways with which you can correct the P012C code:

• You can always replace the turbo/supercharger inlet pressure sensor
• There can be some with the powertrain control module, which can cause problems. So you must get it repaired or replaced
• Replace your supercharger if it is damaged

There is no need to get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of air intake filter, wiring harness, fuel pressure sensor and a lot more. We are sure that now all your issues would be resolved.

The first and foremost thing which you should do is to 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.

That’s 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’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 auto 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 P012C Code

• Inlet pressure sensor can start failure
• There can be some failure in the powertrain control module
• Issue of wiring can arise
