There are hundreds of codes that could trigger your CHECK ENGINE LIGHT. Even the most common reasons can have many possible causes. Some top CHECK ENGINE LIGHT codes are:

• Problem with the Mass Air Flow (MAF) sensor or circuit.
• System Running Too Lean. An oxygen sensor detected a lean condition (too much oxygen in the exhaust)
• System Running Too Rich: The oxygen sensor detected a rich condition (or a too-high fuel to oxygen ratio)
• Cylinder Misfire: A P0300 series of codes indicates a random or multiple misfire in your engine.
• Knock Sensor Circuit Malfunction: Your vehicle's computer constantly adjusts and retimes the engine so that it doesn't produce harmful pre-ignition detonation or knock.
• Insufficient EGR (Exhaust Gas Recirculation) Flow
• Catalyst System Efficiency below Threshold
