Why is the engine malfunction indicator light flashing yellow?

[DiRemington]

Abnormal engine oxygen sensor triggering the malfunction indicator light is a common occurrence. Below is an introduction to relevant information: Abnormal engine oxygen sensor: Typically located near the intake manifold, aggressive driving or certain collision scenarios can cause displacement or damage to the oxygen sensor, leading to sensor abnormalities and triggering the malfunction indicator light. Engine malfunction: If the engine malfunction indicator light remains illuminated, it indicates that the vehicle's engine has a malfunction. A diesel vehicle diagnostic scanner can be used to inspect the engine system and clear the malfunction code. If the indicator light turns off, there is no issue. If the light remains on, read the malfunction code and proceed with repairs based on the diagnostic information. Reasons for the engine malfunction indicator light flashing yellow: False malfunction. A malfunction code is reported, but the engine operates normally. This may result from an operation that exceeded the computer's control range, causing the computer to feedback a malfunction code. The code can be cleared initially, and then observe if it reappears; minor malfunction. The engine shows no obvious issues, but further inspection based on computer diagnostics reveals a minor malfunction that does not significantly affect driving. Prompt identification and resolution are needed, such as an intake pressure sensor malfunction; major malfunction. Such malfunctions can be detected visually and through driving experience, severely affecting the engine's normal operation and requiring immediate repair. For example, noticeable engine power loss may indicate an oxygen sensor issue.
