The check engine light is a warning that the vehicle computer has detected a fault. Reading a diagnostic trouble code is a useful first step, but the code does not automatically identify the failed part.
Flashing versus steady warning light
A flashing check engine light can indicate a condition that risks vehicle or catalyst damage and deserves prompt attention. A steady light still requires diagnosis, particularly when accompanied by rough running, reduced power or unusual noises.
Why code reading is not a complete diagnosis
A trouble code points technicians toward a system or detected condition. Proper diagnosis can require live data, electrical testing, smoke testing, mechanical checks or manufacturer-specific procedures.
