Elimination method of epc lamp

The troubleshooting methods for the lighting fault of automobile EPC lamp are as follows:

1, air intake system troubleshooting, fuel selection criteria, cleaning throttle body, etc.

2. Remove carbon deposit and clean related parts. Rewriting ECU related data (which cannot be eliminated after solving other faults) does not rule out the possibility caused by other faults. The actual vehicle test results shall prevail, and then the maintenance shall be carried out.

3. When the vehicle starts self-inspection, the EPC light will light up for a few seconds and then go out. If something goes wrong, this light will come on. If the battery is low, the EPC fault light will light up. It is generally recommended to go to the 4S shop for inspection and maintenance.

The role of EPC electronic throttle

1. Electronic throttle is an important control part of automobile engine, which is composed of engine, speed sensor and throttle. The electronic throttle control system can accurately control the throttle opening.

2. Control the safety, power, ride comfort, economy and environmental protection of automobiles: In order to control various performances of automobiles, an electronic throttle with good control characteristics and its corresponding electronic control system are introduced to form an electronic throttle control system (ETCS).

3. Precise control of throttle opening: Using electronic throttle control system to accurately control throttle opening can not only improve fuel economy and reduce emissions, but also make the system respond quickly and obtain satisfactory handling performance; On the other hand, it can realize the integration of idle speed control, cruise control and vehicle stability control and simplify the structure of the control system.
