What is the normal throttle opening degree?

During idle, the throttle opening degree is generally between 2~5 degrees. Throttle introduction: The throttle is the most important component of today's electronically fuel-injected engine systems. Its upper part connects to the air filter, and the lower part connects to the engine block, serving as the throat of the car engine. The throttle opening degree refers to the opening angle of the engine throttle. The driver adjusts this angle via the accelerator pedal, and different throttle opening degrees indicate different engine operating conditions. Notes: During idle, the engine speed is related to the throttle opening degree. If the throttle angle is too large, it will cause the engine speed to be too high. If the opening degree is too small, it may lead to engine shaking or even stalling.
The normal range of throttle opening is typically between 5% and 100%, but this is not a fixed value and depends on the specific situation. For example, at idle, when the engine is at low speed, the opening is generally around 5% to 15%; during startup or smooth acceleration, it may rise to 20% to 70%; and with the throttle fully pressed, the opening can reach 100%. Many factors can influence this, such as engine type, throttle response system, or ambient temperature. Normal values ensure fuel efficiency and stable power output. An excessively high opening may indicate an intake blockage or sensor malfunction, while an excessively low opening could suggest throttle sticking or control unit issues. I recommend monitoring the dashboard while driving or using an onboard diagnostic tool to read the values. During routine maintenance, avoid aggressive driving to prevent abnormal fluctuations in throttle opening, which could affect the vehicle's lifespan.
