Q
can a check engine light clear itself
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Yes, a check engine light (CEL) can indeed clear itself, but this depends on the nature of the issue that triggered it. Modern vehicle systems continuously monitor and retest various sensors and operational parameters. If a fault that caused the CEL to illuminate is no longer detected during these retests over several driving cycles (a cycle typically includes starting the car, driving, and turning it off), the system may decide the issue is resolved and turn off the light. However, this doesn't necessarily mean the underlying problem is permanently fixed. Temporary glitches or intermittent issues might temporarily disappear but could return. Always approach a CEL with caution; it's wise to have a professional diagnose the issue even if the light turns off on its own. Ignoring persistent problems can lead to more significant vehicle damage and costly repairs.
