Does the car throttle need to be matched after cleaning?

After cleaning the car throttle, it needs to be matched. The steps for cleaning the throttle are: 1. Turn off the ignition switch and remove the negative terminal of the battery; 2. Remove the throttle cable, intake hose, and screws fixing the throttle in sequence; 3. Clean the throttle with a cleaning agent, and use a cotton swab to wipe areas that are hard to reach. The throttle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. The effects of a dirty throttle include: 1. Engine shaking during idle; 2. Insufficient power when driving; 3. Increased fuel consumption; 4. The vehicle is prone to stalling; 5. Emissions do not meet standards.
I've cleaned the throttle body several times, and it's indeed necessary to perform a reset after cleaning, otherwise the idle speed may become unstable or the car may shake severely. This is because after carbon deposits are removed, the throttle position changes, but the ECU still uses the old parameters. The reset allows the system to recalibrate the sensors. My old car required a manual reset, such as disconnecting the negative battery terminal for 5 minutes, then starting the engine and letting it idle for 10 minutes to relearn. Newer cars might adapt automatically, but it's still best to perform a reset after cleaning. I recommend doing it yourself: turn the ignition switch three times to reset the system, or use an OBD scanner for a simple operation. If you skip the reset, fuel consumption may increase, and the engine light might even come on. Regular cleaning can reduce this issue, and after resetting, the throttle response becomes more sensitive, making the drive much smoother. For safety, take a short test drive of a few kilometers after the reset to check the condition.
