The P0299 code on a Chevrolet Cruze indicates a problem with the turbocharger or supercharger system’s performance. This code is set when the Engine Control Module (ECM) detects that the actual boost pressure in the intake manifold is less than the desired boost pressure.
Code P0299 on a Chevy Cruze
There are several possible causes for this code, including:
- Boost pressure sensor malfunction
- Turbocharger wastegate stuck open or closed
- Boost pressure control solenoid malfunction
- Blocked or restricted intake or exhaust system
- Failed turbocharger or supercharger
To diagnose the specific cause of the P0299 code on your Chevrolet Cruze, you will need a diagnostic scanner or code reader that can read and interpret live data from the engine. This will allow you to check the boost pressure sensor, wastegate, and other components in the turbocharger or supercharger system.
If you are not comfortable with diagnosing and repairing the problem yourself, it is recommended to take your vehicle to a qualified mechanic or dealership for diagnosis and repair.
Code P0299 on a Chevrolet Cruze possible causes
Table: Possible causes of the P0299 code on a Chevrolet Cruze and some comments on each:
| Possible Causes | Comments |
|---|---|
| Boost pressure sensor malfunction | The boost pressure sensor measures the actual pressure in the intake manifold and sends this information to the ECM. If the sensor is faulty or not reading correctly, it can cause the ECM to set the P0299 code. A faulty sensor can be diagnosed with a scanner that can read live data from the engine. |
| Turbocharger wastegate stuck open or closed | The wastegate controls the amount of exhaust gases that flow through the turbocharger, which in turn controls the amount of boost pressure generated. If the wastegate is stuck open, the turbocharger will not generate enough boost pressure, while a wastegate stuck closed can cause too much pressure. This can be diagnosed with a scanner or by inspecting the wastegate actuator and linkage. |
| Boost pressure control solenoid malfunction | The boost pressure control solenoid is responsible for regulating the amount of pressure that the turbocharger generates. If the solenoid is faulty or not functioning properly, it can cause the P0299 code. This can be diagnosed with a scanner or by inspecting the solenoid for damage or leaks. |
| Blocked or restricted intake or exhaust system | A blocked or restricted intake or exhaust system can cause a reduction in airflow to the engine, which can cause the turbocharger to generate less boost pressure. This can be diagnosed by inspecting the air filter, intake ducts, and exhaust system for blockages or restrictions. |
| Failed turbocharger or supercharger | If the turbocharger or supercharger has failed or is not functioning properly, it can cause the P0299 code. This can be diagnosed by inspecting the turbocharger or supercharger for damage or wear, or by checking for abnormal noises or vibrations during operation. |

Code P0299 on a Chevrolet Cruze Description
The P0299 code on a Chevrolet Cruze indicates a problem with the turbocharger or supercharger system’s performance. It is a generic powertrain code that is triggered when the Engine Control Module (ECM) detects that the actual boost pressure in the intake manifold is less than the desired boost pressure.
The turbocharger or supercharger system is responsible for increasing the amount of air that flows into the engine, which in turn increases power and performance.
The boost pressure is the amount of pressure that the turbocharger or supercharger generates and is controlled by the wastegate, boost pressure control solenoid, and other components.
When the ECM detects that the actual boost pressure is less than the desired pressure, it will set the P0299 code and illuminate the Check Engine Light (CEL). This can cause a variety of symptoms, including reduced power and acceleration, poor fuel economy, and increased emissions.
The possible causes of the P0299 code on a Chevrolet Cruze include a faulty boost pressure sensor, stuck wastegate, faulty boost pressure control solenoid, blocked or restricted intake or exhaust system, and failed turbocharger or supercharger.
Diagnosing and repairing the specific cause of the code requires a diagnostic scanner or code reader that can read and interpret live data from the engine, as well as knowledge and experience in turbocharger or supercharger systems.
How much does it cost to diagnose Code P0299 on a Chevy Cruze?
The cost to diagnose the P0299 code on a Chevy Cruze can vary depending on the location and the service provider. However, the typical range for diagnosis can be between $80 to $150.
Some repair shops may offer a free diagnosis if they are going to perform the repair work, while others may charge a diagnostic fee regardless of whether the customer decides to have the repairs done at their shop.
It is important to note that the cost of diagnosis is separate from the cost of repairs, which can vary depending on the specific cause of the P0299 code.
Repair costs can range from replacing a faulty boost pressure sensor, which can cost around $100 to $200, to replacing a failed turbocharger or supercharger, which can cost upwards of $1,000 or more.
It is recommended to get a written estimate from a qualified mechanic or dealership before agreeing to any diagnostic or repair work. This will help to ensure that you have a clear understanding of the costs involved and can make an informed decision about the necessary repairs.
How to fix Code P0299 on a Chevy Cruze?
The appropriate solution for fixing the P0299 code on a Chevy Cruze depends on the underlying cause. Here are some possible solutions based on the common causes of this code:
- Faulty boost pressure sensor: The boost pressure sensor should be replaced with a new one. The new sensor must be calibrated to ensure accurate readings.
- Stuck wastegate in the turbocharger: The wastegate should be inspected to determine whether it is stuck open or closed. If it is stuck open, the wastegate actuator may need to be replaced. If it is stuck closed, the wastegate can be adjusted or replaced as necessary.
- Faulty boost pressure control solenoid: The boost pressure control solenoid should be inspected for leaks or damage. If the solenoid is defective, it should be replaced.
- Blocked or restricted intake or exhaust system: The intake and exhaust systems should be inspected for blockages or restrictions. Any blockages should be cleared or removed to restore proper airflow.
- Failed turbocharger or supercharger: If the turbocharger or supercharger has failed, it will need to be replaced. This is a more extensive repair that can be costly.
It is recommended to have a qualified mechanic or dealership perform the repairs needed to fix the P0299 code on a Chevy Cruze. They will have the necessary tools and expertise to diagnose and repair the specific cause of the code.
