Your CEL and Bad Spark Plugs

Does Your Car Lack Spark?

What do Spark Plugs Do?

Spark plugs are a very important component of your engine. They are the part which produces the spark to ignite the fuel and oxygen to drive the pistons in your engine and creates the energy to move your vehicle. When the spark plugs are worn or failed, your engine won’t start or remain running and your vehicle won’t move. A spark plug is a part in your engine that wears out with time and use, so you should expect to replace them at some point in the life of your vehicle. Because they’re an internal component of your engine, you might wonder how to tell if the spark plugs in your vehicle should be replaced. To help you with this problem, car manufacturers have added faulty, worn, and failing spark plugs to the error faults in the sensors your vehicle’s computer uses to turn on your check engine light (CEL).

What’s the Connection Between the CEL and Your Spark Plugs?

One of the errors that trigger the CEL on your dashboard is a problem with your spark plugs. If you’re also noticing rough idling, trouble accelerating, bad fuel efficiency, and trouble starting your vehicle, that CEL is probably caused by a problem with your spark plugs. However, the only way to know for certain what has caused your CEL to come on is to take your vehicle to a service center like Titan Auto and Tire in North Chesterfield, VA, for a computer diagnostic service.
