Error Code P012E: What It Means & What To Do?

<<See All OBD Codes

The OBD Code P012E powertrain control failure can be defined as a turbocharger/supercharger inlet pressure circuit high

It is the powertrain control module which would monitor the turbocharger/supercharger inlet pressure sensor circuit signal. The powertrain control module would then set the OBD fault code when the turbocharger/supercharger inlet pressure sensor signal is out of factory specifications.

Do you want to learn more about P012E fault code? Then you have arrived at the best place. The turbocharger/supercharger inlet pressure sensor would tell the engine control module that how much amount of air is being forced into the engine. When an incorrect signal is detected by the powertrain control module from this sensor, then it would set P012E fault code. Due to this the vehicle would be sent into the “limp home mode” and this would limit the power of the engine and would thus protect the other components from getting damaged.

What causes this problem with the Turbocharger/Supercharger Inlet Pressure Sensor Circuit Intermittent/Erratic Downstream Of Throttle Valve?

• There can be some issues 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 - There can be some issues with the Powertrain Control Module due to which you may see P012E code appearing over and over again. Visit us to buy best quality Powertrain Control Module online.
2. Inlet Pressure Sensor - Are you facing some faults in your Inlet Pressure Sensor? Don’t worry and get them replaced or else P012E code can turn up.
3. Turbocharger - Common cause behind this P012E error code can be some fault in Turbocharger. So, it will be a good decision to replace them now.
4. Supercharger - Timing Chain is perfectly fine but still but having that trouble code P012E flashing? In such a situation your Supercharger might be faulty. Why don’t you think of getting that replaced?
5. Throttle Valve - The P012E code can also arise due to some issues in Throttle Valve. So, it is advised to replace them as soon as possible.
6. Intake Manifold - Do you remember when was the last time you got your car Intake Manifold checked up? A damaged Intake Manifold can cause a lot of issues like displaying P012E code.

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 P012E. 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

Have a look at some ways with which you can correct the P012E code:

• First of all, you should replace the turbo/supercharger inlet pressure sensor
• Issues with the wiring harness 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, relay wiring, 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. 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’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 auto 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 then the best option would be to get it repaired or replaced.

Common Mistakes When Diagnosing the P012E Code

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