Every time you turn the key in the ignition, several computers communicate to all the engine systems to control their operation. As you begin to drive, all these computers work together to perform precise adjustments on how your vehicle is responding to different factors, like the speed you are driving, how much air and fuel to mix together, the engine temperature and more. When something isn’t running quite right and your vehicle starts to emit more pollutants, the on-board diagnostic (OBD II) system sends a signal that triggers the Check Engine or Service Engine Soon light. If this light is on, there is a problem with engine performance.
Why did the Check Engine or Service Engine Soon Light come on?
The Check Engine Warning light comes on when there is a problem somewhere in the emissions system. Not only is your vehicle not running the way it should, it’s also producing more pollutants. The emissions and exhaust systems in your vehicle work together to keep the engine running cleanly and efficiently. They transform the noxious gases from your engine into gases that are safer to breathe and for the environment. Some of the main parts in the emissions/exhaust system include the OBD II, catalytic converter, the Power Control Module (PCM), oxygen sensors, muffler, intake and exhaust manifolds and exhaust pipes. A problem in any one of these parts can result in the OBD II triggering the warning light to come on.
When a Check Engine or Service Engine light comes on, you may not even notice a problem with the way your vehicle is running, yet the OBD II has identified a problem. While no one wants to see the Check Engine or Service Engine Soon light come on, it’s not something that should be ignored. Most times, it’s a minor problem with the emissions system that can be fixed relatively quickly. However, if you ignore this light, what was a minor problem will eventually become a major repair issue. Quite often, damage will occur to the catalytic converter, which is a very expensive part to replace.
Here’s what to do if the Service Engine Soon or Check Engine light won’t turn off
One of the simple fixes for a Check Engine Light has to do with the gas cap. The first thing you should do is make sure the gas cap is properly tightened. You will then need to drive your car, truck or van for about 50 miles for the OBD II to go through all its checks. If the problem occurred because the gas cap was loose, the light will turn off. If that doesn’t work, it’s probably best to schedule an appointment at our auto repair shop located in Verona, New Jersey. Our ASE-certified technicians will be able to perform computer diagnostic engine testing to locate and fix the problem that is causing the light to come on.
