Check Engine Light Diagnosis

Honda Oxygen Sensor Failure

Also known as an O2 sensor, this device measures the ratio of unburnt oxygen in your car's exhaust system. If this sensor is damaged or stops working, your vehicle will burn more fuel than normal, resulting in lower fuel economy, more frequent fill-ups, and more atmosphere emissions. For these reasons, a faulty O2 sensor will trigger a check engine light. A great way to learn if this is causing your check engine light is to come into Tom Wood Honda of Anderson. Our mechanics know exactly what to look out for and how to fix it quickly.

Loose Fuel Cap

In other cases, it's a simple mistake that can be fixed in seconds. If your check engine light comes on, you should first check your fuel cap. Even if it's on snug, go ahead and unscrew it then screw it back on. In some cases, the cap may not be adequately seated, causing gas to escape from the gas tank. This triggers a check engine light to illuminate.

Catalytic Converter Failure

On the more serious side, a failed catalytic converter could also cause a check engine light. This device helps convert carbon monoxide into carbon dioxide, turning a potentially lethal gas into a less harmful one. If you live in Anderson, IN, you should have your catalytic converter checked every time you get an oil change. Our certified and factory-trained technicians can quickly spot this issue and potentially get your sorted out before work with our early bird service.
