But the light as a way to mean keep problems and prolong the life of a car. Often says it is warning about problems, which can be avoided by you with regular maintenance, CarMD, a manufacturer of vehicle diagnostic devices.

While maintenance is expensive, it is crucial how are people to their cars longer. According to r.l. Polk, an automotive data company, is the average vehicle on the road now 10.6 years, up from 8.8 years a decade ago.

Here are the five most common reasons that your "check engine" light could come, and what you can expect for the repair work, including figures according to CarMD:

The catalyst used catalyst - in most cases a precious metal such as Platinum - harmful gases to less harmful emissions from combustion left convert. CarMD says, that catalysts in general fail will not if has some related, such as such as a spark plug, malfunctions, so it is wise to keep up with the maintenance schedule of the vehicle.

4. Error mass air flow sensor
This sensor measures the amount of air supplied to the engine that determines how much fuel should be delivered. If it malfunctions, it can a loss which makes the car run surges during acceleration and a decrease in fuel economy. It costs around $375 to fix.

5. Misfiring spark plugs
Spark plugs are small but absolutely necessary, because they drive the car you make with the lighting of the compressed fuel in an internal combustion engine. Amazing may interfere with spark plug engine power and efficiency and can damage the catalytic converter also. You can replace spark plugs for less than $10 or numbers $300 for a technician to do it.

CarMD says, that the entire average repair costs in the United States $305.56, $202.28 for parts and $103,27 for labor, including is.

The most expensive cars to repair? Hybrids. They are rarely trained enough that their parts are more expensive and less technicians, to fix them.
