What Is Your ‘Check Engine’ Light Telling You?



The Car Care Council reports that one out of 15 vehicles checked at its National Car Care Month Vehicle Check-Up Events had its “check engine” light brightened.

This light is one of the most vital components to a correctly functioning automobile. It signals the motorist to a range of potential issues based on the car’s on-board diagnostic system.

When the check engine light comes on, it suggests that a system in your vehicle – such as ignition, fuel injection or emission control – is not operating at peak efficiency, even if your lorry seems running usually.

A glowing check engine light does not suggest you should immediately stopped to the side of the road, but you must get the cars and truck took a look at as soon as possible. Neglecting the caution light might seriously harm engine components and sustain additional repair expenses.

If your check engine light comes on, first check the gas cap to make sure it wasn’t left loose after refueling. In some cases this can activate the light. If the cap was loose, the light needs to head out after a few short journeys.

If the light remains on, have the system inspected out as soon as possible. A light that flashes shows a more serious condition that needs to be taken a look at right away to avoid damage to the catalytic converter. When you experience a flashing light, reduce owning at high speeds or under heavy loads.

When scheduling service, ensure the vehicle shop that detects your automobile has expert technicians who are appropriately licensed for OBD II (on-board diagnostic systems) medical diagnosis and repair work. The specialist will connect your car’s computer to a diagnostic computer system, which will offer a “trouble” code indicating why the light was activated.

While the diagnostic computer is connected to your cars and truck, the professional can inspect the idle speed, throttle action, engine temperature level, fuel system pressure, manifold vacuum, exhaust emission levels and many other crucial indicators.

When the problem is detected and repaired, your car’s computer makes sure everything is back to normal, then turns off the check engine light.

The Car Care Council advises reading your automobile owner’s handbook and familiarizing yourself with the purpose of the check engine light and each gauge and warning indication on your dashboard.
