What Does EPS Mean on a Car?

December 4, 2023

EPS is an acronym for electronic power steering. The system helps the car owner save fuel by reducing engine output to turn the wheels. The EPS system also makes it easier for drivers to steer their vehicles. However, like any other vehicle part, it can fail. When the EPS light turns on, it's important to take the vehicle to a professional auto shop immediately.

The EPS warning light is easy to recognize as it looks like a yellow, orange or red steering wheel often accompanied by an exclamation mark. In cars that don't use hydraulic power steering, the illuminated EPS initial communicates the same message.

If the EPS light comes on, it indicates that the computer has detected an issue with the power steering system of the vehicle. Unlike the hydraulic power steering system, this one uses an electric motor to help turn the steering rack. The computer collects information from the steering angle sensor and the vehicle speed sensor to decide how much assist to provide.

EPS systems are more efficient than hydraulic systems and are a lot safer to drive. But they're not infallible, and a malfunctioning EPS system can cause your vehicle to turn the wheels hard or make it difficult to maneuver during driving. This can lead to a serious accident, so it's best to get the car repaired as soon as you notice any signs of EPS malfunctioning. If your car's EPS light turns on, you should pull over and check the wiring connections to the battery. If they're not in place, you should replace the battery and have a professional perform a full diagnostics to determine the problem.
