Below is a list of the most common reasons your check engine light can come on:

• Your 2012 Chevy Volt has a vacuum leak. Each Chevy Volt has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower adverse emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to intense heat or extreme cold.

If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more costly. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on promptly after you put gas in your 2012 Chevy Volt, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.

This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will experience a noticeable poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.

If there is excess oxygen in your exhaust system, fuel burns more rapidly and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2012 Chevy Volt's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the definitely correct mix of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can again cause a car to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2012 Chevy Volt if it’s not installed properly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting.
