How to fix Ford code P0299?
The Ford code P0299 indicates an issue with the turbocharger or supercharger system. This diagnostic trouble code is triggered when the engine control module (ECM) detects a discrepancy between the expected and actual boost pressure. Resolving this problem requires identifying and addressing the underlying cause. Here's a detailed guide on how to fix the Ford code P0299.
Understand the Code P0299
The P0299 code is specifically related to the turbocharger or supercharger system. It indicates that the actual boost pressure is lower than the expected boost pressure. This can be caused by a variety of issues, including a malfunctioning turbocharger, a problem with the boost control system, or a leak in the intake system.
Diagnose the Problem
To fix the P0299 code, you'll need to diagnose the underlying issue. Here are the steps to diagnose the problem:
- Check for any visible signs of damage or leaks in the turbocharger or supercharger system. Inspect the turbocharger, intercooler, and all the hoses and connections for any cracks, holes, or loose fittings.
- Use a scan tool to read any additional diagnostic trouble codes. Other codes may provide more information about the specific problem, such as a faulty turbocharger actuator or a boost control solenoid issue.
- Perform a boost test. Use a pressure gauge to measure the actual boost pressure and compare it to the expected boost pressure. This can help identify the source of the problem.
- Check the engine air filter. A clogged air filter can restrict airflow and cause a drop in boost pressure.
Once you've identified the root cause, you can proceed to the repair process.
Repair the Problem
The specific repair steps will depend on the underlying issue identified during the diagnosis. Here are some common solutions for the P0299 code:
- Replace the turbocharger or supercharger. If the turbocharger is faulty, it will need to be replaced.
- Replace the boost control solenoid. A malfunctioning boost control solenoid can cause the actual boost pressure to be lower than expected.
- Repair any leaks in the intake system. Seal any cracks, holes, or loose fittings in the intake system to ensure proper boost pressure.
- Replace the engine air filter. A clogged air filter can restrict airflow and cause a drop in boost pressure.
After completing the necessary repairs, clear the diagnostic trouble code and test the vehicle to ensure the problem has been resolved.
By following these steps, you should be able to effectively diagnose and fix the Ford code P0299, restoring proper turbocharger or supercharger operation and resolving the underlying issue.
Can a bad map sensor cause a P0299 code on a Ford?
Fix a P0299 Code With a New Turbo or MAP Sensor
The P0299 code is stored because the vehicle's sensors detect that the turbocharger isn't creating enough boost pressure. Either a turbocharger or the sensor itself could be faulty.
What is the most common cause of P0299?
Typical Causes
Typically, this code is the result of an air restriction or leak in the intake of your engine. Another common cause is a binding turbocharger or simply a faulty pressure sensor.
How do I fix the code P0299 on my Ford?
Repairs for a P0299 error code usually include replacing the turbo/supercharger, repairing the intake system, replacing the EGR, repairing low engine oil pressure, or replacing the boost pressure sensor.

How to fix a P0299 OBD-II trouble code?
- Confirm the fault code with an OBD-II scanner, and then reset.
- Repair or replace any loose or damaged parts of the intake air system which could be causing a pressure leak (common)
- Replace air filter.
- Repair low engine oil pressure issue.
How long can you drive with a P0299 code?
No, you can't still drive with a P0299 code. In fact, most vehicles will enter limp mode when this code is activated. Limp mode results in less engine power, a lower top speed, and several other power-saving measures that make it impossible to drive far.
What happens if you keep driving with a bad turbo?
The short answer is that you can still drive your car with a blown or damaged turbo. However, the longer you drive it in this state, the more damage the engine will have and the more expensive repair bill you will get.
Can a bad catalytic converter cause underboost?
Catalytic converter problems are not the only thing that can cause a turbocharger to cease working. But if your cat goes bad by becoming clogged, it likely will affect your turbo's performance. Usually, what happens is your engine's turbocharger will be deprived of the air it needs to work.
What are the symptoms of a bad turbo boost sensor?
If the Turbo Boost Pressure Sensor is failing, your vehicle may display the following symptoms:
- Lack of power.
- Poor acceleration or hesitation.
- Rough idle.
- Increased emissions or failed emissions.
- Check engine is illuminated.
How do I fix my Ford code P0299?
Repairs for a P0299 error code usually include replacing the turbo/supercharger, repairing the intake system, replacing the EGR, repairing low engine oil pressure, or replacing the boost pressure sensor.
How do I know if my turbo boost sensor is bad?
If the Turbo Boost Pressure Sensor is failing, your vehicle may display the following symptoms:
- Lack of power.
- Poor acceleration or hesitation.
- Rough idle.
- Increased emissions or failed emissions.
- Check engine is illuminated.
