The service engine soon light, commonly referred to as the check engine light, on a 2000 Chevy Silverado, or any vehicle, can have a number of meanings depending on the issue. If the light is steady, it typically indicates a minor problem, such as a loose gas cap or a failing oxygen sensor. However, if the light flashes, it indicates a severe problem that could potentially damage the catalytic converter.Know More
If the check engine light is on, the engine control unit stores a fault code related to the malfunction. Mechanics can use a scanner tool to see what error or malfunction the light is referring to. The light does not usually indicate any serious issue with the vehicle and should be viewed as a warning. A car can continue running without issue for a long time even if the check engine light is on; although, this is not to say the light cannot occasionally indicate serious trouble.
Often, a check engine light may turn off immediately after repairs but come back on shortly thereafter. This is due to the on-board diagnostics (OBD) system performing constant maintenance tests. Certain tests require specific conditions to be met before they complete, such as the vehicle being off for a certain time or traveling for a certain distance; this can result in the check engine light staying on until the conditions are met and the tests are completed.Learn more about Car Parts & Maintenance
If the problem has been diagnosed and fixed but the check engine light is still on, either use an auto scan tool or simply disconnect and reconnect the battery. If there is still a problem with the engine, disconnecting the battery and resetting the light will not make the light turn off. Also, if the vehicle's radio has an anti-theft setting, disconnecting the battery may make the radio stop working until a specific code is put in to fix it.Full Answer >
