If you live in the city and mostly drive short distances, take your car on the highway every now and then to ensure the catalytic converter doesn’t get clogged. Performing regular maintenance (such as oil changes) on time is key to keeping your car’s catalytic converter in working order. Every late-model car that runs on gasoline has a catalytic converter. That’s good news because a new one costs between $200 and $600 depending on the make and model. It’s a fairly simple part, and its failure can often be prevented. It turns the carbon monoxide generated during the combustion process into carbon dioxide. The catalytic converter is integrated into a vehicle’s exhaust system. Most auto parts stores carry universal-fit gas caps that cost somewhere in the vicinity of $15. Sometimes the cap needs to be replaced, but it’s not a problem that’s going to hit your wallet hard. If your check engine light turns on immediately after a fill-up, pull over and make sure the cap isn’t loose - or still on your car’s roof. It notably prevents gasoline fumes from leaving the fuel tank, and it helps keep the whole system under the correct pressure. The cap is a crucial part of a car’s fuel delivery system. Loose fuel cap John Wolf/123rfĪ loose fuel cap is one of the most common reasons why the check engine light turns on. Finally, keep in mind that most late-model cars have more than one O2 sensor. On average, a quality O2 sensor will set you back about $175, but the cost of labor will vary greatly depending on the vehicle’s make and model, as well as your geographical location. It may also cause a car to fail an emissions test. In the long run, a bad O2 sensor can damage components like spark plugs and the catalytic converter. An engine will keep running even if an O2 sensor needs to be replaced, but it will burn more fuel than usual. It sends data to the vehicle’s computer, which uses it to regulate the mixture of air and fuel that enters the cylinders. The oxygen sensor (sometimes called an O2 sensor) measures the amount of unburnt oxygen in a car’s exhaust system.

Keep in mind that the fault code that caused the light to turn on in the first place is stored in your car’s onboard computer, and you can retrieve it using a simple Bluetooth-powered device linked to an app to get a precise idea of what exactly is wrong under the hood.
Here are the 10 most common problems that can trigger a check engine light. Don’t ignore it, either, and get it checked out as quickly as possible.
