If you’re getting a p0299 code, you’re probably losing power and noticing some odd behavior in your vehicle when you hit the accelerator. It could be that the car is struggling to hold a steady idle, or it might be shuddering or stuttering when you try to accelerate.

This code indicates that your vehicle is having difficulty controlling the pressure in its turbocharger system, specifically its intake manifold. There are things that can cause this problem, which we will discuss in more detail below.

Turbochargers deal with incredibly high levels of pressure that are higher than you probably have on your tires. It is important that you keep them in good shape by taking care of both the engine and exhaust.

If either one of these components isn’t up to par, it can wreak havoc on your turbocharger system and cause problems like a check engine light, loss of power, or even complete failure of your vehicle.

If you’re seeing this code pop up on your diagnostics readout, make sure you get it checked by a professional mechanic as soon as possible.


What causes code P0299?

P0299 is a relatively common OBD-II diagnostic trouble code indicating a low boost condition. There are many possible causes you will get the code, and it’s important that you troubleshoot and resolve the problem as soon as possible.

A code P0299 may mean that one or more of the following has happened:

  • There is a vacuum leak in the intake manifold.
  • The turbocharger or supercharger wastegate isn’t functioning properly.
  • The turbocharger or supercharger has failed.
  • The exhaust gas recirculation (EGR) valve may not be operating properly.
  • Other possible causes include damaged or worn-out piston rings, damaged cylinder head gasket, and blown head gasket on the exhaust side of the engine.

How do I fix error P0299?

Error P0299 is a generic error, which means that the code is not necessarily correct. The error indicates that there is an issue with the car’s turbo or supercharger. To fix this error, start by checking all electronics associated with the turbo or supercharger system, including the wastegate solenoid and bypass valve.

If these parts are working correctly, check the vacuum system to make sure that it is not creating a false reading. If none of these fixes work, you will most likely need to replace the turbocharger or supercharger itself.

How much does it cost to fix the P0299 code?

The good news is that P0299 is usually a fairly simple issue to fix and consequently doesn’t require much time or money to correct. It typically costs around $100 for a professional mechanic to diagnose and repair this issue.

The average cost of fixing P0299 is $250-$350, with most mechanics charging $300 total for parts and labor. They will usually replace the IAC valve or clean it if it’s dirty (which causes these issues).

If there are other codes present on your vehicle, too (like P0300), then you’ll probably pay more than $350 total because those will take longer to repair.

Can you still drive a car if the turbo goes out?

Yes, you can still drive a car if the turbo goes out. A turbocharger is an exhaust-driven air compressor that is used to increase the power of an internal combustion engine. It’s basically like a fan, but it’s built into your engine and can be turned on or off when you want to use it.

When your turbocharger isn’t working, you might notice that your car is harder to start than usual or maybe that the engine has trouble revving up when you step on the gas pedal. However, if you’re careful about how much you accelerate and how quickly, your car should run just fine without a turbocharger.

Can a dirty air filter cause a P0299 code?

Yes, a dirty air filter can cause this code to be triggered. The P0299 code means that the vehicle’s computer has detected a problem with the powertrain control module (PCM).

This code is usually triggered by a short circuit in the PCM, but it can also be triggered by a dirty air filter if the filter becomes clogged with too much dirt.

When an air filter becomes clogged with too much dirt, it can cause the engine to lose power and run poorly. A dirty air filter could also cause a P0299 code if it clogs up one of the sensors on your engine.

Can an exhaust leak cause P0299?

Yes, an exhaust leak could cause a P0299 code. A P0299 code indicates that the Turbo or Supercharger “A” Low input is too low. The ECM (engine control module) measures the boost pressure level and compares it to the desired boost pressure (the target or desired boost pressure is determined from the mass airflow reading).

If the actual boost pressure is lower to the target boost pressure, then your vehicle has a turbocharger or supercharger under boost conditions. A leaking exhaust system can be a common cause of an under-boost condition.

Check for any loose or damaged hoses or clamps in your exhaust system that may be leaking. A leaky exhaust system can also cause loss of power and poor fuel economy.

Can the p0299 code damage the car?

The good news is that although the P0299 trouble code can be pretty scary, it’s not necessarily going to damage your car.

The bad news is that while it won’t cause damage, in some cases, it will cause a lot of problems.

If the P0299 trouble code comes up, it’s because your car’s engine is producing too much pressure. This can happen if:

  1. The exhaust backpressure is high
  2. There is a problem with the turbocharger or supercharger bypass valve
  3. There’s an issue with the boost control system
  4. There’s something wrong with the fuel pump or fuel injection system

If you see this trouble code, don’t wait around to get it checked out, and you will need to get an expert diagnosis to tell you which of these (or other) causes is at fault so that you can fix it before it does any serious damage.

Importance of turbo in a car?

The importance of turbo in a car is that it can help you get more power out of your engine. Turbochargers are often used on high-performance cars, but they’re also used on some low-end vehicles as well.

Turbochargers do have their downsides, though. They take up space, and they’re expensive to install. Some people don’t like the way they sound either (although many turbocharged cars have mufflers that make them sound quieter than non-turbocharged ones).

Here’s how turbos work: when air is forced into the engine at high speeds, it creates a lot of pressure which causes more fuel to be sprayed into the cylinders. This creates more power for acceleration and deceleration because more fuel means better combustion in each cylinder.

The downside is that turbos aren’t good for fuel economy since there’s more energy being used up by the engine overall, which leads us to another important point: fuel economy suffers when using a turbocharger because it uses up so much energy from each gallon of gas burned through its cylinders; however, this can be solved by using premium gas instead of regular unleaded gasoline (which has lower octane levels).”

What happens if the turbo has low output?

If the turbo has a low output, it is likely that the compressor or turbine wheel bearings are worn. This can be caused by dirt or debris in the lubricating oil or a lack of lubrication.

It can also be caused by the compressor or turbine wheel being damaged. This can happen if the turbo is installed incorrectly and the blades rub against something in the engine bay, such as a component of the exhaust system. The problem could also be a lack of lubricating oil, which can cause bearing damage.

If the turbo has a low output, it can be caused by:

  • Defective or worn-out turbocharger
  • Defective wastegate actuator
  • Sticking vanes in the turbocharger
  • Air intake obstruction (e.g., dirt)
  • Exhaust system obstruction (e.g., kinked exhaust pipe)

The list above is not exhaustive but covers some of the most common causes of low turbo output. The best way to determine which issue is causing your turbo problems is to have a diagnostic test done at a mechanic’s shop.


The p0299 code is a generic OBD-II code related to a problem with the vehicle’s powertrain system. The code can indicate any number of problems in that system, including transmission issues and engine problems.

If your car has a p0299 code, it means that there is an issue with one or more of your vehicle’s emissions-related systems. The p0299 code is not specific enough to indicate exactly what kind of problem you’re dealing with, but it does point you toward the correct area for further investigation.

The first thing you should do if your car throws this code has it diagnosed by an expert technician at a certified emissions testing facility.
