Modern vehicles are equipped with on-board computers that monitor the critical systems in your car and warn you when something is going wrong. This diagnostic system communicates with the engine and transmission and adjusts performance according to set manufacturer parameters. When any of these set parameters are found outside of the acceptable range, the check engine light becomes lit.
There are hundreds of codes that could trigger your CHECK ENGINE LIGHT for dozens of reasons each. Even the most common reasons can have many possible causes.
Below is a list of a few of the possible problems that could cause your Check Engine light to activate.
- Loose gas cap
- Problem with the Mass Air Flow (MAF) sensor or circuit
- System running too lean or too rich
- Cylinder misfire
- Knock sensor circuit malfunction
- Insufficient EGR (Exhaust Gas Recirculation) flow
- Catalyst system efficiency below threshold
- Faulty Oxygen Sensor
Our Check Engine Light Services include:

- Interpret and analyze the diagnostic fault code that registers the nature of the issue
- Locate specific problem
- Discuss diagnostic and repair options if needed
- Check smog-related components
Whatever you do, don’t ignore it and go about your business, especially if it is flashing. Cars just need a little love from time to time to stay in good shape, and neglecting a minor issue could lead to bigger problems down the road. Finally, you certainly cannot pass state mandated Emission/Smog inspection with your CHECK ENGINE LIGHT on.
