The P0299 code on a Chevrolet Cruze is related to the turbocharger/supercharger underboost condition. This means that the power output of the turbocharger/supercharger is lower than expected.
Code P0299 on a Chevy Cruze
There are several reasons why this code may be triggered, including:
- Faulty or dirty mass air flow sensor
- Clogged air filter
- Leaking or damaged intake or exhaust system components
- Malfunctioning turbocharger wastegate
- Faulty turbocharger/supercharger bypass valve
- Electrical issues in the turbocharger/supercharger system, such as damaged wiring or a blown fuse.
To diagnose and repair this issue, it is recommended to take the vehicle to a qualified mechanic who can perform a thorough inspection and run diagnostics on the engine control module (ECM) to identify the specific cause of the underboost condition.
Depending on the underlying issue, repairs may involve replacing faulty components, cleaning or replacing the air filter, or performing other maintenance tasks to restore the proper functioning of the turbocharger/supercharger system.
P0299 code on a Chevrolet Cruze possible causes
Table: Possible causes of the P0299 code on a Chevrolet Cruze and comments on each cause:
| Possible Cause | Comments |
|---|---|
| Faulty or dirty mass air flow sensor | The mass airflow (MAF) sensor measures the amount of air entering the engine and sends this information to the engine control module (ECM). If the MAF sensor is faulty or dirty, it can cause inaccurate readings, which can lead to the P0299 code being triggered. Cleaning or replacing the MAF sensor may be necessary. |
| Clogged air filter | The air filter prevents dirt and debris from entering the engine. If the air filter is clogged, it can restrict the amount of air entering the engine, which can cause the P0299 code to be triggered. Replacing the air filter may be necessary. |
| Leaking or damaged intake or exhaust system components | Any leaks in the intake or exhaust system can cause a loss of pressure, which can lead to the underboost condition that triggers the P0299 code. Checking for and repairing any leaks may be necessary. |
| Malfunctioning turbocharger wastegate | The wastegate is a valve that controls the amount of exhaust gas flowing to the turbocharger. If the wastegate is malfunctioning, it can cause the turbocharger to underperform, leading to the P0299 code being triggered. Repairing or replacing the wastegate may be necessary. |
| Faulty turbocharger/supercharger bypass valve | The bypass valve is responsible for regulating the pressure in the turbocharger/supercharger system. If the valve is faulty, it can cause the pressure to drop, leading to the underboost condition and triggering the P0299 code. Repairing or replacing the bypass valve may be necessary. |
| Electrical issues in the turbocharger/supercharger system | Electrical issues, such as damaged wiring or a blown fuse, can cause the turbocharger/supercharger system to malfunction, leading to the P0299 code being triggered. Inspecting the electrical components and repairing any issues may be necessary. |
It’s important to note that this is not an exhaustive list of possible causes, and a qualified mechanic should perform a thorough inspection and diagnosis to determine the specific cause of the underboost condition and P0299 code.

Code P0299 Chevrolet Description
The P0299 code is a generic powertrain code that is triggered when the engine control module (ECM) detects that the power output of the turbocharger or supercharger is lower than expected. This code is common in Chevrolet vehicles equipped with turbochargers or superchargers, such as the Cruze.
The ECM monitors the performance of the turbocharger or supercharger and uses various sensors, such as the mass air flow (MAF) sensor, to determine the amount of air entering the engine. If the ECM detects that the power output of the turbocharger or supercharger is lower than expected, it will trigger the P0299 code and illuminate the check engine light on the dashboard.
There are several reasons why the P0299 code may be triggered, including a faulty or dirty MAF sensor, a clogged air filter, leaking or damaged intake or exhaust system components, a malfunctioning wastegate or bypass valve, or electrical issues in the turbocharger or supercharger system.
When the code is triggered, it can cause several symptoms, such as reduced engine power, hesitation or stalling, turbocharger or supercharger noise, and poor fuel economy. To diagnose and repair the issue, a qualified mechanic will use a scan tool to access the ECM and perform a series of tests to determine the cause of the underboost condition.
