Engine Diagnostics Q & A

  • What's causing my car's check engine light to come on?

    There’s an exhaustive list (literally hundreds)of reasons why a vehicle’s check engine light may come on, but here’s a short list of common reasons:

    Mass Air Flow (MAF) sensor.

    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 misfire in your engine.

    Knock Sensor

    Insufficient EGR (Exhaust Gas Recirculation) Flow

    Catalyst System Efficiency below Threshold : The oxygen sensor after the catalytic converter is detecting that the converter is not working as efficiently as it should be (according to specs).

  • If my check engine light is on, will it pass NY State Inspection?

    If you’re check engine light is on, it will not pass the NY Inspections. When the inspection is performed, the computer is connected to your vehicle via the OBDII (On-Board Diagnostics) connector. This test will read and detect any emission-related issue with your vehicle.


  • What are trouble codes, and how do they relate to the check engine light?

    When your Check Engine light comes on, a trouble code will be stored in your vehicle’s computers. There are certain conditions that have to be met for a trouble code to set properly. Our technicians thoroughly check all trouble codes before service/repair solutions are offered.
