What does the EPS light indicate as a fault?
2 Answers
EPS light indicates a fault in the Electric Power Steering system. The causes of Electric Power Steering system failure include: 1. Damage to the steering system sensor. 2. Failure of the steering system motor. 3. Insufficient or leaking power steering fluid. Below is an introduction to related content: 1. If the EPS light is on, it is necessary to promptly go to the nearest 4S store for maintenance, as damage to the EPS system can affect the car's steering and impact normal driving. 2. The Electric Power Steering system directly provides steering assistance through an electric power motor, eliminating the need for components such as the power steering pump, hoses, hydraulic fluid, drive belt, and pulley mounted on the engine required by hydraulic power steering systems, which saves energy and protects the environment.
The EPS light being on mainly indicates a malfunction in the electric power steering system. As someone who often tinkers with cars, I've encountered this issue several times. Common causes include low battery voltage leading to unstable power supply, errors in the steering angle sensor causing inaccurate data readings, or internal issues with the control unit module requiring a reset or replacement. You can perform simple checks yourself: first, ensure the battery terminals aren't corroded or loose, and use a multimeter to check if the voltage is normal; inspect the fuse box to see if the relevant fuses are blown and try replacing them. However, if the light turns off after restarting the vehicle but comes back on, don't take it lightly—this means the underlying issue hasn't been resolved. For a deeper diagnosis, connect an OBD scanner to read the fault codes for precise identification. Ignoring this can make the steering wheel excessively heavy at low speeds, such as when reversing into a parking spot, making it difficult to control and increasing the risk of scraping obstacles. Therefore, it's advisable to visit a professional repair shop as soon as possible to prevent safety risks from worsening.
