P0299 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you keep encountering the error P0299? The Turbo or Supercharger “A” might have an excessively low output. You can go through the below manual which will help you pinpoint the pain points that might be causing the error. 

The basic mechanism is that the ECU searches for a specific range of boost and on detecting a low boost, it sets off the P0299 error code. Given below are a few conditions that might be causing the error code P0299 to be generated and thus causing you inconvenience.

The conditions in which the error code is generated:

• Restriction or leakage in the Intake (induction) air
• Failed or damaged turbocharger (sticking, binding, etc.)
• Faulty Boost/charge Pressure sensor
• Faulty Wastegate bypass regulator valve (VW)
• Low fuel pressure condition (Isuzu)
• Sticking turbo nozzle control solenoid (Isuzu)
• Injector control pressure (ICP) sensor is faulty (Ford)
• Oil pressure is low (Ford)
• EGR system is faulty (Ford)
• Variable geometry turbocharger (VGT) actuator (Ford)
• VGT vanes sticking (Ford)

If your vehicle is showing you the error value of P0299, there might be a fault in some ancillary or related parts that might need to be fixed. The below given might be an exhaustive list that can help you pinpoint where the trouble lies. You might need to replace these parts with the new models that can easily be found at the online aftermarket stores:

1. Supercharger - The supercharger itself might be faulty. You can get it checked or have it replaced at quite affordable prices. The supercharger is vital to the pressure regulation of the intake systems of the vehicle and thus should be kept in a perfect state.
2. Pressure - The automotive systems are pressure sensitive and a faulty pressure system might as well be the reason for the error.
3. Solenoid - A solenoid creates an electromagnetic field for induction of charges. A solenoid replacement might help in eliminating the P0299 error.
4. Turbocharger - The turbocharger might have run out of the steam and might need repair or replacement to do away with the error. A healthy Turbocharger means more power created by the engine. This will improve the efficiency quotient of your vehicle.
5. Sensor - The sensors might be getting weak or not responding perfectly and this could be causing the error code. Failure in sensors might lead to big troubles if these are not checked in time. You don’t want to prolong the problems till they start costing you hefty amounts. It is better to get the sensors checked in time if the error code P0299 is being generated so that you can prevent any future problems that might come up.
6. Control Pressure - The Fuel Injector control pressure valve might be faulty and might need replacement for the full efficiency.

When there’s something wrong with the system, there are always external signs that can help us pinpoint the pain area that might be generating the error codes. For a situation where you find yourself facing the error code P0299, we have listed down a few symptoms that can be a tell-tale sign of the error code and why it might be generated. These are the common symptoms that would appear for this error code. If these are noticed, you should immediately carry out an extensive test.

Common Symptoms

• Check if the engine light is illuminated
• See if the vehicle might be going in a limp mode
• The engine might be lacking power
• See if you can hear a mechanical noise. This might indicate a failing turbo/supercharger

Have a look at some ways with which you can correct the P0299 code:

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 Super Charger, Pressure, Solenoid, Turbocharger, Sensor, Control Pressure or and many more. Now all your problems would vanish within no time.

The first thing a mechanic might do when you take your vehicle for an extensive test to root out the causes for an error being generated in your vehicle, is to hook up a scanning tool into your vehicle’s OBD-II port and check for the presence of any codes.

• The freeze frame data will be noted, which includes all the information about the conditions the vehicle was under when the code was set.
• The Technician will then clear all these codes and perform a test drive.
• He or she will then perform a visual inspection of the turbo/supercharger system, the intake system, EGR system, and other such associated systems which might be affected and thus causing the error.
• The scan tools will then be used to check for proper boost pressure readings.
• The technician will inspect all the mechanical systems such as the turbo or supercharger, oil pressure and the intake systems for the possibility of any leaks or inspections.

Common Mistakes When Diagnosing the P0299 Code

Not following all the steps in the proper order might lead to mistakes being made. P0299 error code can have a wide variety of causes and will show a range of symptoms. An accurate diagnosis will hugely be based on following the diagnostic steps in a proper manner.
