Error Code P012B: What It Means & What To Do?

<<See All OBD Codes

Are you facing some Defects in the turbocharger/supercharger inlet pressure sensor? Do you remember that was your Turbocharger/Supercharger Inlet Pressure Sensor harness was opened or shorted? Did your mechanic tell you that Turbocharger/Supercharger Inlet Pressure Sensor circuit is facing bad electrical connection? We know that you trapped in this nasty situation. If you are facing all these issues, then the OBD Code P012B would appear.

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 P012B trouble 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 Range/Performance 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 - A lot of issues can arise do to defective Powertrain Control Module. Did you just see P012B code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
2. Turbocharger - OBD Code P012B can appear because of faulty Turbocharger.
3. Supercharger - Common cause behind this P012B error code can be some fault in Supercharger. So, it will be a good decision to replace them now.
4. Pressure Sensor - The P012B code can also arise due to some issues in Pressure Sensor. So, it is advised to replace them as soon as possible.
5. Engine Pressure Sensor - Engine Pressure Sensor is an important auto part. Take care of it and you can rely on us to purchase best quality Engine Pressure Sensor online.

Willing to know some common symptoms of OBD Trouble Code P012B? Your wish is our demand. Have a look at them below:

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

Here are some ways with which you can correct the P012B code:

• You should do is to 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

Don’t 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.

Make sure that you visually inspect 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 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 P012B Code

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