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