What is damaged when the fault code u0101 appears?

Fault code u0101 is an error indicating a dirty throttle issue. Below is an introduction to throttle-related content: 1. Function: The throttle controls 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 generate power. 2. Principle: The principle of the throttle is that the traditional engine throttle control mechanism operates via a cable (flexible steel wire) or rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle primarily uses a throttle position sensor to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.
Having worked on cars for so many years, I've encountered the U0101 trouble code quite a few times. It generally indicates a loss of communication between the transmission control module and other systems. Possible causes include loose or corroded wiring connectors, most commonly at the plugs near the control module. The module itself could also be faulty, such as freezing or burning out. When diagnosing, first check if the battery voltage is stable - if it's too low, it might cause communication issues. Also inspect all relevant fuses, as a blown fuse can sometimes cause major problems. Ignoring this code may lead to rough shifting, strong jerking sensations when driving, and prolonged issues could potentially damage the transmission. So when detected, promptly confirm with a diagnostic scanner. Never randomly disconnect wires - safety first. It's best to have a professional shop trace the root cause.
