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.
