Turbo Actuator Position Sensor

Modern Variable Turbo Geometry (VGT) turbo systems are electronically controlled by the vehicle’s Electronic Control Unit (ECU). The ECU is able to calculate the exact amount of turbo boost required by the engine thanks to its sensors. One of these sensors is the turbo actuator position sensor. This important sensor is responsible for reporting to the ECU the position of turbo vanes in real-time. Thanks to the turbo actuator position sensor the ECU can regulate the exhaust flow passing through the turbocharger with increased accuracy.

A faulty turbo actuator position sensor usually causes turbo vanes to stop moving since the ECU can no longer detect their exact position. Depending on the position of the vanes, the vehicle may lose power and produce too little or too much boost. Thus, as a direct consequence of the turbo actuator position sensor fail you may be at risk of overboost.

At Turbo Vanes we count with an incredible inventory of turbo actuator position sensors that will solve this issue. Our compromise is only providing high-quality turbo parts, that’s why we work with top aftermarket brands such as:

• HELLA

Browse confidently our comprehensive selection of turbo actuator position sensors, choose one that fits your vehicle specifications and leave the rest to us. Before you even notice it you will have your new turbo actuator position sensor at the location of your choice.

TURBO PROBLEMS AND FAQS What does it mean when your car goes into Limp Mode? You can think of “Limp Mode” as an “emergency mode” used by your vehicle Electronic Control Unit (ECU) to protect the engine and transmission from serious damage. The “Limp Mode” feature programmed in the ECU can reduce engine power, turn off A/C, and sometimes manipulates the automatic transmission to allow you to drive the car safely. If the Check Engine Light is lit or the information center is showing up a warning message, then we strongly suggest to pull over or drive to the closest repair shop. Driving for prolonged periods of time in Limp mode may cause major mechanical breakdowns to the engine and/or transmission. It’s safe to drive my car in Limp mode? Absolutely. The Limp mode allows you to drive your vehicle (with reduced power) so you can reach your destination. Once you get home or any other safe place, it’s strongly suggested to book a visit with a local repair shop to diagnose the root of the problem.

(Common Causes and Solutions) Turbo overboost most common causes are air leaks, damage on turbo internal parts, debris impacting the turbo, a blocked VNT mechanism, or wrong turbo actuator settings. With the exception of air leaks that can be easily fixed changing the appropriate gaskets, most of these issues will require repairing and/or replacing your turbocharger or turbocharger internal parts. What causes a turbo low boost? (Common Causes and Solutions) An underperforming turbo boost is commonly caused by air leaks, a clogged air filter, damage on turbo internal parts, worn engine components, a blocked VNT mechanism, or a restricted turbo air pipe connection. Air leaks, air filter, and air pipe issues can be easily fixed by a competent mechanic, however, the rest of these issues will require repairing and/or replacing your turbocharger or turbocharger internal parts. What are the VNT turbo vanes? VNT turbo vanes consist of a mechanism inside the turbocharger that helps to decrease engine lag at low RPM as well as preventing turbo overboost at high RPM. To achieve this goal, turbo vanes are operated by a turbo actuator (either vacuum-operated or electronically controlled by the ECU) to increase or reduce exhaust flow. facebook google twitter contact faqs news
