Throttle valve is a controllable valve that controls entry of air into the engine. It plays a critical role in engine operation and has direct implications for engine performance, fuel efficiency, and environmental protection. Common reasons for throttle valve failure include the following:

1. Carbon accumulation: The accumulation of carbon due to long-term use can cause the throttle valve switch to become unresponsive or stuck.

2. Sensor malfunction: Malfunction of the throttle valve position sensor (TPS) can interfere with the ECU's control of the throttle valve.

3. Electrical issues: Loose wire, short circuit, or corroded connector can result in poor signal transmission.

4. Mechanical wear: Wear of the mechanical components of the throttle valve, especially the bearing and hinge, can affect normal operation.

5. Valve body damage: The throttle valve body may crack or deform due to external load or environmental factors.

6. Leakage of air intake system: If there is a leak in the air intake pipeline, it will affect the intake air flow and throttle valve performance.

7. ECU software issues: Failure or the need for updates of the software of the electronic control unit (ECU) may cause abnormal throttle valve control.

8. Failure of coolant temperature sensor: If there is a problem with the sensor that controls the engine coolant temperature, it may lead to improper adjustment of the throttle valve.

9. Throttle valve motor failure: A damaged motor can cause the throttle valve to fail to open or close.

Advantages of vika STO throttle valve:

Net technology: return spring structure

The vika STO throttle valve dispenses with the traditional two-stage structure, and uses imported 304 stainless steel material. It has passed 7.5 million cycles of fatigue test with high fatigue strength.

Net technology: angle position sensor

The vika STO throttle valve features enhanced interference resistance and can effectively prevent damage caused by static electricity to chips. 360-degree signal reception ability leads to higher accuracy and sensitivity.

New product: throttle valve flap

vika STO throttle valve: Anodizing treatment reduces oil adhesion.

New material: transmission gear

vika STO throttle valve: The combination of PA66, GF30, and PTFE15% materials leads to lower friction coefficient and smoother gear operation.
