What does a turbo air control valve do?
The Turbocharger Boost Pressure Valve controls pressurized air (60psi) going to the pneumatic turbo actuator. The replacement restores proper engine performance and power.
What does a turbo actuator do?
The turbo actuator does a simple but vital job – it acts as a pressure relief valve that controls the boost output of your turbo, diverting excess exhaust gases away from the turbine wheel. This controls the speed of the turbine, preventing it from over-speeding, and regulating the speed of the compressor.
Can you rebuild a turbo actuator?
We completely rebuild your actuator using original replacement components. We replace all faulty components or high-wear parts as bearings, bushings and defective electronic components. New high-quality SILICONE gaskets. Professionally rebuilt – meets or exceeds as new item requirements.
How do I know if my turbo actuator is bad?
Actuator failure – signs and symptoms
- A flashing engine management light.
- Complete loss of power, causing the vehicle to enter limp mode.
- Intermittent low pressure.
- Low boost.
- Overboost.
- Noise from the turbocharger.
- ECU error symptoms control.
- Fault codes.
What happens when turbo actuator fails?
If the electronic actuator has failed to open the nozzle ring assembly vanes under acceleration, the turbo will also fail to operate efficiently. If the vanes are set to a closed position, it can cause choking of the engine or overspeeding of the turbine.
How do you know if your turbo actuator is bad?
There are a few factors which determine an actuator failure:
- Flashing engine management light;
- A complete loss of power, causing the vehicle to go into limp home mode;
- Low boost;
- Over boost;
- Noise from the turbocharger;
- Fault codes.
