In the automotive industry, electronic controls are becoming more and more sophisticated. Many systems, from the transmission to the engine system and even braking, are now governed by sensors and processors to increase safety and reliability. These advanced systems make it possible for your car to function in ways that were never imagined before, but they also mean that there are more potential issues that could arise. When an EPC light turns on, it means there is a problem with the computer that controls several aspects of your vehicle. In this article, we will discuss what the EPC warning light indicates and how to fix it.
All sensors and systems in your car rely on a specific baseline voltage to operate correctly. If any system or sensor experiences a significant drop in this voltage, the EPC will illuminate and a dashboard warning will be triggered. If the problem is serious, the vehicle may enter limp home mode, which limits power and acceleration to prevent further damage.
It is important to understand what the EPC warning light indicates so you can take your car to a professional mechanic to have it checked out as soon as possible. If you ignore the warning light, it can lead to further problems and expensive repairs down the road. In order to diagnose the issue, a mechanic will plug an OBD2 scanner into your car’s computer and read its trouble code. Once the code is found, the mechanic will perform any necessary repairs to return your vehicle to normal operation.
