How does a turbo electronic actuator work?
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.
What does D4D mean?
Direct Injection 4 Cylinder Common Rail Diesel Engine
What is a D4D Toyota Engine? D-4D actually stands for Direct Injection 4 Cylinder Common Rail Diesel Engine. Common rail diesels injects a fine mist of fuel into the engine at very high pressure.

What kind of engine does a Toyota 1KD have?
The 1KD engines ousted the Toyota KZ engine series. But now the 3.0-liter version is rapidly being replaced by the new Toyota GD engine – the 2.8L 1GD-FTV. The 1KD-FTV engine has a cast iron cylinder block with two counter-rotating balance shafts driven by a gear on a crankshaft. The engine block doesn’t have liners.
Are there any problems with the Toyota D-4D engine?
Copper seats under the common rail injectors can fail. That issue is common for late 2004-2007 model years. The main symptom is a white smoke from the exhaust. Also, there is a problem with injectors itself. The common rail system is sensitive to fuel quality. But even with high-quality fuel, the injectors can fail around 80,000 miles (120,000 km).
What should I do if my Turbo is not working?
Before you start the process, we recommend checking the air filter, exhaust system, breather system and fuel system on your vehicle are all working properly, as these can cause similar symptoms to turbo failure. Once you’ve done that, you’ll need to remove the air filter to gain access to the turbo.
