The Five Most Common Causes of a Check Engine Light and What You Should Do About Them. You're driving home from work one day when the car owner's worst nightmare happens: the check engine light pops on. It comes without warning and with no explanation. For most drivers, this means a trip to the mechanic, but it's not difficult to diagnose (and sometimes fix) yourself. Photo by Robert Couse- Baker. It's just a light with no information telling you what the problem is. It's a cry from a baby with no explanation. But you can do a few things yourself before heading into the shop for costly repairs. Aside from the one commenter who called me a . Call ahead and make sure they can handle your make and model, since some cars have special computers. Once you're at the store, they'll come out and plug a small computer underneath your dashboard and read back a code stating what happened to the car. According study conducted by Car. MD, five common malfunctions cause the check engine light to come on, and several of them are simple to fix yourself. Let's take a look at the most common issues. One: Replace Oxygen Sensor An oxygen sensor is a part that monitors the unburned oxygen from the exhaust. It helps monitor how much fuel is burned. A faulty sensor means it's not providing the right data to the computer and causes a decrease in gas mileage. Most cars have between two and four oxygen sensors and the code you get from the scanner will tell you which one needs replacing. What causes it: Over time, the sensor gets covered in oil ash and it reduces the sensors ability to change the oxygen and fuel mixture. A faulty sensor not only reduces gas mileage, it also increase emissions. What you should do: Not replacing a broken oxygen sensor can eventually lead to a busted catalytic convertor which can cost upwards of $2,0. Taking your car into a shop will cost you around $2. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. TIGHT FIVE (1999) IMDB: tt0191738. Actors: Eric Young, Keith Quinn, Peter Fitzsimmons.

Regardless of how you approach it, you should get this fixed right away. Two: Loose or Faulty Gas Cap. You wouldn't think a gas cap would be that important, but it is. When it's loose or cracked, fuel vapors leak out and can throw the whole fuel system off. This causes a reduction in gas mileage and increases emissions. What causes it: If you get an error pointing to the gas cap it means fuel vapors are leaking out of your cap. This means the cap is either cracked or just wasn't tightened well enough. What you should do: If your car isn't feeling jerky or strange when the check engine light comes on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off. Alternately, you can purchase a gas cap for about $3 at an auto parts store. All you need to do is take the old one off and screw on the new one. If you've already made it to the store, you might as well just replace it. While not car- threatening, it's good to take care of this right away to improve gas mileage.
