What does the check engine fault mean?
2 Answers
check engine fault means to check the engine, there is a fault in the engine. When the vehicle is in motion, if the engine system sensor or switch fails, the computer will provide a preset value to allow the engine to continue running, while controlling the check or check engine light on the instrument panel to illuminate, reminding the driver to take the vehicle to the maintenance shop for inspection. If the system is normal, the check engine light flashes twice per second. If the check engine light cannot flash the fault code when entering the diagnostic function and remains continuously lit, when the ignition switch is turned to the ON position, check the TEL (or T), which must have battery voltage.
As an average car owner, I remember feeling quite panicked the first time I saw the 'check engine' light illuminate on my dashboard. Later, I learned that this is the engine malfunction indicator light, signaling that the vehicle's engine management system has detected an anomaly, typically related to emissions—such as a faulty oxygen sensor, clogged fuel injector, or catalytic converter issues. While these minor problems might not immediately affect driving, prolonged neglect can lead to decreased fuel efficiency, diminished engine performance, and increased environmental pollution. My advice is not to ignore it: first, use an OBD scanner to read the trouble codes, which can pinpoint the specific issue, then visit a professional repair shop for servicing, such as replacing worn components. Addressing it early can save significant repair costs. For instance, after spending a few hundred dollars to fix my sensor issue last time, my fuel consumption returned to normal.
