The EPC system uses many different engine sensors to work correctly and if there is a problem with one of them, it could result in the EPC warning light. ![]() The clock spring has been known to fail and if it does, it might look like a problem with the steering angle sensor. In order to turn the steering wheel, there is a clock spring where the wires to the steering wheel angle sensor and steering wheel buttons go. The EPC system will take this information to determine which direction you have turned the steering wheel and then correct the brake force using this information. You will find the steering angle sensor located behind your steering wheel and it is used to measure what position the steering wheel is in. ![]() Keep in mind, a replacement can be expensive.

If you have a Volkswagen and the EPC light comes on your dashboard, there is a good chance the brake pressure sensor failed. It can cause problems with the ABS reluctor ring where the ABS sensor measures the speed. The ABS sensors are located on the wheel hubs and are continually exposed to dirt, water, and dust which can lead to failure. It takes this information for the ABS system as well as other systems that use the information and the EPC system is one of those systems.
