CHECK ENGINE. There's nothing fun about those two words. There's also not a lot of logic to be gathered from them. Check engine? Could they be a little more specific? Nope, they can't. That's because the Check Engine light comes to life if anything, and we do mean anything isn't 100% under the hood. This means that you could be staring at a major repair, or your gas cap could be too loose (no kidding).

Unfortunately, the majority of recurrent Check Engine episodes eventually lead to some professional repair time. The most common problems that trigger the light are emission control malfunctions. The emission control system is what your car uses to try to keep our air a little cleaner. To do this, it employs dozens of sensors, valves, flaps, heated wires. Every car made in the last 20 years has at least one oxygen sensor (we saw a Toyota that had four of them recently), and they don't last forever. If they go, expect around $300 per sensor in replacement costs.

But don't throw your wallet in the street just yet. There are also plenty of little things that can make the Check Engine light come on, and many are easily corrected. Here are a few of the more commonly occurring issues: Gas cap loose- you would be suprised at how often we clear this trouble code. Your engineand ECM got wet and the computer controls don't like that - Try to avoid using a pressure washer directly on electronic componenets. Spark plug wires bad or old - As your spark plug wires start to get old, they may develop tiny cracks which can let little bursts of electricity out.
