Can I still drive with the EPC light on?

It is not recommended to continue driving when the EPC light is on, as the fault may affect the normal operation of the vehicle. Here are the solutions for when the EPC light is on: 1. Troubleshoot the intake system, use compliant fuel, and clean the throttle body; 2. Remove carbon deposits from related parts; 3. Rewrite the ECU-related data; 4. Do not rule out the possibility of other faults, and the specific issue should be determined by reading the fault code. If the EPC light is on but the vehicle shows no obvious signs of malfunction, you may continue driving, and the driver can try turning the engine off and restarting it to turn off the EPC light. Even if there are no signs of malfunction, the driver should not be complacent and should promptly have the vehicle inspected and repaired.
Never take the EPC light lightly, and I'm speaking as a veteran driver with over 20 years of experience who's encountered this issue several times. That flashing light usually indicates a problem with the engine's electronic control system, such as a clogged throttle body or a faulty throttle position sensor, which can lead to reduced power or even stalling—serious risks on highways. I recall once during a business trip when the EPC light came on mid-journey, and my car immediately slowed to a snail's pace, forcing me to pull over with hazard lights on. My advice is to slow down and find a safe spot to inspect the situation as soon as the light appears; pushing through is too risky, potentially resulting in a breakdown or worse, an accident. It's best to have a professional repair shop diagnose the exact cause with a scanner. Regular throttle body cleaning during maintenance can help prevent this issue. If you're on a short trip, maintaining a steady speed might be feasible, but always be prepared to stop—safety comes first.
I think if the EPC light comes on, sometimes you can still drive cautiously for a while, like us young people who commute daily. Last time the light came on, I still drove to the office. Usually, when that light appears, it's often due to minor issues like sensor false alarms or loose wiring. The power might be downgraded with speed limited, but the car can still barely move. At that time, I kept my speed low, around 40 km/h, avoiding highways and heading straight to a repair shop to check the situation, and everything went smoothly without any incidents. However, you should be alert if other warning lights come on together or if the car shakes abnormally, as that indicates a serious problem requiring immediate stopping and seeking help. It's advisable to stay calm and not panic, continuing to drive short distances to test while heading to an auto repair shop as soon as possible for a computer diagnosis to avoid more costly repairs later.
