CHECK ENGINE LIGHT ON?

Top Reasons Your Check Engine Light May Be On:

• A 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: Random or multiple misfires in your engine.
• Knock Sensor Circuit Malfunction
• Insufficient EGR (Exhaust Gas Recirculation) Flow
• Catalyst System Efficiency below Threshold
