What should I do if there is an exhaust system obstacle during sagitar driving and the EPC light is always on?

The light of EPC is mainly caused by dirty throttle body. This situation can only be solved by cleaning the throttle and re-matching. It is also possible that there is a leak in the air intake system, which causes the engine control unit to light the EPC warning light after detecting the problem. Failure of the brake light switch can also cause this phenomenon.

But if the EPC light is on all the time, it may be caused by dirty throttle. At this time, computer testing is needed to troubleshoot.
