Top 10 check-engine-light car repairs

No. 1 car repair: Failing oxygen sensor

Average repair cost: $293.88

Oxygen sensor malfunctions are the most common car repair. The O2 sensor can fail as a result of neglecting car repairs or simply by using gas with a higher concentration of ethanol.

Because the sensor works with the car's onboard computer to create the fuel-to-air ratio, a malfunction can result in as much as a 40 percent drop in fuel economy and can affect performance. The average cost of car repairs increased nearly 20 percent over the previous year.
