HOW IT WORKS:
The Check Engine Light location and color will vary by vehicle, but in most cases it is a dashboard warning light that is yellow and shaped like an engine.
Any number of indicators and warning icons are part of the on-board diagnostics system. When the engine icon appears, it indicates a problem with your emissions system. A Check Engine indicator will stay solid or blink. A blinking indicator usually indicates a serious condition and a visit to a qualified mechanic ASAP. A steady light is not an emergency situation. You can continue driving, but you should schedule an appointment soon.
COMMON REASONS FOR THIS TO HAPPEN:
While a Check Engine Light can come on for a number of reasons, in most cases it is due to one of the following conditions:
- A loose or damaged cap can reduce your gas mileage and increase emissions from your car. Always check, inspect and tighten your gas cap. If the light stays on, schedule an appointment with a mechanic.
- Faulty oxygen sensor: If you have a faulty sensor, it will not provide the correct data to the onboard computer. Deterioration of the oxygen sensor affects the sensors’ ability to give an accurate reading. A faulty oxygen sensor can eventually damage your catalytic converter. Get an accurate diagnosis ASAP.
- Failing catalytic converter: A failing converter will affect your gas mileage and performance. In most cases, a catalytic converter is designed to last the life of the car. A failing converter can be the result of a faulty oxygen sensor that has not been replaced. A damaged or worn catalytic converter will not pass an emissions test and should be replaced immediately.
- Faulty mass airflow sensor: When a mass airflow sensor starts to fail, the car will stall, idle poorly, emissions will go up, and your gas mileage will go down. Also, don’t forget to have your air filter checked and replaced on a yearly basis.
- Bad spark plugs and wires: Newer cars can go 100,000 miles on a set of plugs, older vehicles require new plugs typically every 30,000 miles. New spark plugs and wires are an affordable fix.
