Regular engine service is the best way to make sure your vehicle provides you with reliable transportation as long as you need it to. If you think you are starting to experience engine problems, the “Service Engine Soon” light illuminating on the instrument panel could be the first warning sign. Unless your car doesn’t run at all, head to your auto shop and ask for a diagnostic test. Your mechanic will plug a small computer underneath the dashboard to “read” what is happening under the hood. Potential problems can be diagnosed while they are small issues before they turn into a major engine repair.
If you’re wondering what can cause a “service engine soon” light to come on, there are several reasons. It could be an easy fix or something more serious is happening under the hood.
- Damaged Gas Cap – If the gas cap is loose or cracked, fuel vapors leak out and can throw the whole fuel system off, reducing gas mileage and increasing toxic emissions. Replacing the gas cap may take care of the problem.
- Faulty Oxygen Sensor – The oxygen sensor monitors the unburned oxygen from the exhaust, and how much fuel is burned. If it is faulty, it cannot provide the right data to the computer, thereby reducing gas mileage and increasing toxic emissions.
- Failing Catalytic Convertor – The catalytic convertor reduces exhaust gases by converting carbon monoxide and other harmful materials into harmless emissions. If it fails, your gas mileage decreases, and your car won’t accelerate when you step on the gas pedal.
- Faulty Mass Airflow Sensor – The mass airflow sensor tells the car's computer to add the proper amount of fuel based on the air coming through to the engine. If it fails (possibly from an improperly installed or clogged air filter), toxic emissions will increase, the car will start to stall, and gas mileage will decrease.
- Dirty Spark Plugs and Wires – The spark plug seals the combustion chamber and provides a gap for a spark to jump across and initiates combustion in your engine. If they are going bad, they will misfire. They simply need to be replaced.
Now, do you understand what is “key” to a well-running engine? To put it simply—take care of all service items as recommended by the manufacturer, thus helping prevent a major and costly engine repair.
