Check Engine Light On?

The right diagnosis is everything and we treat it like a science. At AAMCO our technicians are skilled specialists who use their expertise and top-notch diagnostic equipment to troubleshoot, so that you save time and money.

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


At AAMCO Tristate centers, our technicians understand the reasons why your check engine light might be on, they’ll quickly pin-point what is causing the problem and will recommend only what needs repair.
