A malfunctioning brake light switch can also cause the EPC light to come on. To replace the brake light switch, locate the switch under the brake pedal and remove it. Install the new switch and test the brakes to make sure everything is working correctly.

The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust system. A faulty oxygen sensor can cause the EPC light to come on.
