What Causes the Inability to Accelerate When the Engine is Warm?

[DeJude]

Hot car can not add oil is caused by the failure of the car's electronic throttle. The electronic throttle replaces the cable or rod with a wiring harness (conductive wire), installs a micro motor at the throttle, and uses the motor to drive the throttle opening, which is the so-called wire driving, replacing the original mechanical transmission mechanism. The following is extended information: 1. Composition of the throttle control system: The electronic throttle control system mainly consists of the throttle pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor, and throttle actuator. The displacement sensor is installed inside the throttle pedal to monitor the position of the throttle pedal at all times. 2. ECU: When it detects a change in the height position of the throttle pedal, it instantly sends this information to the ECU. The ECU performs operational processing on this information and other data transmitted from other systems, calculates a control signal, sends it to the servo motor relay through the circuit, and the servo motor drives the throttle actuator. The data bus is responsible for communication between the system ECU and other ECUs.
