Reasons why the engine yellow light flashes and then disappears: It may be an intermittent fault, most likely an issue with the oxygen sensor. Sensor Introduction: Automotive sensors are input devices for the vehicle's computer system. Sensor Function: They convert various operating condition information (such as vehicle speed, temperature of various mediums, engine operating conditions, etc.) into electrical signals and transmit them to the computer to ensure the engine operates in the optimal state. Sensor Definition: When troubleshooting faults related to automotive sensors, in addition to inspecting the sensor itself, it is also necessary to check the wiring harness, connectors, and the relevant circuits between the sensor and the electronic control unit.
