What is the solution for sluggish electronic throttle response?
2 Answers
To address sluggish electronic throttle response, an electronic throttle accelerator can be installed. Below is relevant information about electronic throttles: 1. Working Principle: The electronic throttle is essentially an electronic throttle body. When the accelerator pedal is pressed, it does not directly control the fuel injection quantity but rather regulates the throttle opening. 2. Throttle Cleaning: Excessive carbon buildup on the throttle can disrupt normal engine operation. When cleaning throttle carbon deposits, it is necessary to remove the throttle. After cleaning and reinstalling, the engine control unit (ECU) must be recalibrated; otherwise, the engine may experience increased fuel consumption in the short term.
I've experienced slow electronic throttle response while driving, where it feels like there's a one-second delay after pressing the pedal before the car moves. This is usually caused by carbon buildup in the throttle body or throttle position sensor, which blocks signal transmission. A simple solution is to clean the throttle body – you can buy a cleaner at an auto parts store and do it yourself. Just open the engine compartment after parking and spray it. Alternatively, try resetting the ECU by turning off the car, disconnecting the negative battery terminal for a few minutes, and reconnecting it. Sometimes this can restore normal function. If there's no improvement, check for loose or worn wiring connections. During my last inspection, I found a faulty connector, and replacing it fixed the issue. Remember to perform regular maintenance to prevent carbon buildup for worry-free driving. In short, start with DIY checks to save money and effort.
