【Abstract】The electronic control components of gasoline engines include sensors，actuators，and ECM. This article mainly introduces in detail two types of electronic control components that often malfunction after sales，namely the carbon canister solenoid valve and the throttle valve body. Starting from the working principle，introduce its technical characteristics，and based on the control principle and common problems，provide relevant maintenance suggestions for fault diagnosis，hoping to provide assistance for after-sales fault analysis and judgment.
