It seems like there might be a mistake in your question - "[what does engine]" appears to be incomplete or missing some context. An engine, in a general sense, is a machine designed to convert one form of energy into mechanical energy. Internal combustion engines, commonly found in vehicles, transform the energy from burning fuel (like gasoline or diesel) into motion.
There are also electric engines, which convert electrical energy into mechanical motion, and steam engines, which were historically significant in the industrial revolution by converting heat from steam into physical labor through mechanical work. The specific function and design can vary widely depending on the type of engine and its intended use, from powering cars and aircraft to generating electricity in power plants.
Resetting a check engine light simply clears the error message from your vehicle's onboard diagnostics system (OBD). However, this action does not fix the underlying issue that triggered the light. If the problem persists, the check engine light will likely illuminate again after some driving. The OBD keeps monitoring various sensors and systems in the vehicle; if it detects the same issue, the light will return. To genuinely resolve the issue, it's important to read the error codes with an OBD scanner, diagnose the problem, and perform the necessary repairs. Ignoring these warnings may lead to more severe and costly repairs down the line. Therefore, while resetting may temporarily remove the light, addressing the root cause is essential for your vehicle's health and safety.
In most cases, a car will not pass inspection with the check engine light on due to emission test failures. The check engine light signals an issue within the vehicle's emission control system or other critical components. Since emissions inspections assess a vehicle's adherence to environmental standards by evaluating the exhaust gases, any malfunction causing the check engine light to come on might result in failure. However, the exact impact depends on your location, as inspection criteria vary. It's advisable to diagnose and repair the underlying issue triggering the check engine light before your inspection. Not only does this increase your chances of passing, but it also ensures your vehicle operates efficiently and safely.
