PWR on the car dashboard stands for Powertrain, also known as Powerplant in English. It refers to a series of components in the vehicle that generate power and transmit it to the road surface. The electronic throttle control system proportionally adjusts to the accelerator opening under all driving conditions, ensuring the engine output power remains appropriate. The electronic throttle control system has three modes. Here is some relevant knowledge about the electronic throttle control system: 1. Normal Mode: Recommended for ordinary driving to save fuel. 2. Power Mode: Used to enhance acceleration and for sporty driving. 3. Snow Mode: Used for slippery road conditions such as ice and snow. In this mode, the rotation of the rear wheels is appropriately controlled.
I wasn’t sure what ETCPWR meant either, but after checking some materials, I found out it should be related to the Electronic Throttle Control (ETC) power system, which is part of the car’s electronic throttle. Simply put, ETC replaces the old cable throttle system and uses electronic signals to open and close the throttle valve to control air intake. PWR here likely refers to the power supply or power mode. If the power supply is unstable—for example, due to an aging battery or insufficient alternator output—it can affect the throttle’s responsiveness, causing sluggish or jerky acceleration while driving. During routine checks, you should verify that the voltage is normal, and regular maintenance of power components can prevent such issues. Remember, unresolved power issues pose a significant risk of overall control failure, so timely repairs are essential for safety. In short, this is a crucial part of vehicle electrification, and maintaining it ensures a worry-free driving experience.
My understanding of ETCPWR is based on experience, and it roughly refers to the Electronic Throttle Control's power module. In a vehicle, the ETC system replaces the mechanical throttle with electronic signals, and the PWR end refers to its power supply section. When the power supply is unstable, such as poor wire contact or a blown fuse, the throttle response may become sluggish or fail. I've encountered similar issues where the car speed fluctuated unpredictably, and later inspection revealed that the generator's excessive power output burned out a relay. I recommend that car owners pay more attention to the battery status and charging system. If any fault codes appear, they should promptly read and troubleshoot them. Safe driving should never be taken lightly—proper power maintenance ensures a reliable vehicle. Don't overlook these small details.
