Check Engine Light On?
When the check engine light is on, turn to Federal Automotive & Towing to check it out so our experts may diagnose the engine light codes and get the repairs you need to get back on the road - lights out and worry-free!

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 Exhaust Gas Recirculation (EGR) Flow
• Catalyst System Efficiency below threshold

These are just a few of the hundreds of codes, causes and symptoms. Each has multiple fixes.

Our expertise in vehicle diagnostics means we can quickly pin-point what is causing your CHECK ENGINE LIGHT to come on and we will recommend only what needs repair. Fixed right on the first visit, every time!
