Is a Throttle Opening of 0% Normal?

It is not normal. Here are specific details about the throttle: 1. The normal value for throttle opening is between 1.6 and 5.0, and values within this range are considered normal. 2. Throttle opening refers to the angle at which the engine's throttle opens. The throttle of a car engine is controlled by the driver via the accelerator pedal to adjust the engine's air intake, thereby regulating engine operation. Different throttle openings indicate different engine operating conditions. 3. The car throttle is a controllable valve that regulates air entry into the engine. After entering the intake pipe, the air mixes with gasoline (the mixing location varies by vehicle design) to form a combustible mixture that participates in combustion and power generation. 4. The throttle is one of the most critical components in modern fuel-injected engine systems. Its upper part connects to the air filter, and the lower part connects to the engine block, making it the 'throat' of the car engine. 5. The responsiveness of a car's acceleration is closely related to the cleanliness of the throttle.
While driving, I noticed the throttle opening displayed at 0%, which immediately seemed off. Under normal idle conditions, the opening should be minimal but never fully zero, as the engine requires a small amount of air to keep running. If the opening stays at zero, the car won't respond during acceleration and might even stall, which is dangerous. After checking, I found it could be due to a faulty sensor or carbon buildup jamming the throttle, causing the system to misread. Prompt cleaning or part replacement can fix the issue. Last time I ignored this problem, fuel consumption skyrocketed, and I nearly got into an accident. So, I recommend getting it checked at a professional shop as soon as you notice it to ensure driving safety.
