What is the reason for the inability to accelerate when the engine is warm?

[SanAlessandra]

The reason for the inability to accelerate when the engine is warm is due to a malfunction in the vehicle's electronic throttle. The electronic throttle replaces the traditional throttle cable or linkage with a wiring harness (conductive wires). A micro motor is installed at the throttle valve, which drives the throttle opening, known as drive-by-wire, replacing the original mechanical transmission mechanism. Here is additional information: 1. Electronic Throttle Control System: The electronic throttle control system mainly consists of the accelerator pedal, pedal position sensor, ECU (Electronic Control Unit), data bus, servo motor, and throttle actuator. The position sensor is installed inside the accelerator pedal to continuously monitor the pedal's position. 2. Benefits: Since the electronic throttle system adjusts the throttle through the ECU, it can incorporate various functions to enhance driving safety and comfort.
