Sagitar epc fault light is on. Do you need maintenance?

Pacific Auto Network sagitar epc fault light is on and needs maintenance. There is too much carbon deposit in the throttle valve, and there is something wrong with the opening. Due to engine misfire and cylinder missing, the throttle valve is not working properly. There is air leakage behind the throttle, and the detection data of the intake pressure sensor is abnormal, which will light the EPC light.

Generally speaking, EPC lights have two possibilities.

First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring.

EPC indicator lights are more common in the public. After the key door is opened, the vehicle starts self-inspection, and the EPC indicator light will light up for a few seconds and then go out. If the vehicle does not go out after starting, it means that the mechanical and electronic system of the vehicle has failed. Generally speaking, EPC lights have two possibilities.

First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring. Also, due to the oil problem, the EPC fault light will also light up. The general public's car EPC light indicates that there is something wrong with the vehicle. It is recommended to go to the 4s shop for inspection as soon as possible! EPC light is on. First, the throttle body is dirty and has carbon deposits. Clean the throttle. Second, the air intake system produces vacuum leakage. Check whether the vacuum hose is firmly connected and broken. At this time, there is a theoretical value between the air flow rate detected by the engine through the air flow meter and the throttle opening (how big the throttle is and how much air is fed), which will cause errors and make the mixture too lean. In both cases, the EPC light will be on.
