5 Common Reasons Why Your Check Engine Light Is On

5 Common Reasons Why Your Check Engine Light Is On

Overview The check engine light is a red flashing light on the dashboard or instrument cluster of your vehicle.

The light indicates a problem with the vehicle's emission system, which can be serious if it remains illuminated for an extended period of time. However, if you are unable to determine the root cause of your check engine light turning on and need a professional mechanic for auto repair in Norcross then contact wrights Car Care right away.

A Sticking Gas Pedal A stuck gas pedal can cause a loss of power at low speeds and reduced acceleration on the highway. If this occurs frequently, it could be a sign that something is wrong with your car's fuel system, such as a leaking fuel filter or cracked fuel lines. If this occurs while driving, you must pull over immediately and address the problem before it worsens and puts other drivers at risk of an accident.

Your Gas Cap Is Sloppy A loose gas cap can cause carbon monoxide to build up in the vehicle's exhaust system. This is due to the fact that carbon monoxide is produced when fuel burns and produces carbon dioxide (CO2). In your cabin, CO2 reacts with oxygen, causing headaches, nausea, and dizziness. A loose gas cap may also indicate other problems with your vehicle.

Low Tire Pressure Warning The Low Tire Pressure Warning (LTPW) system uses a sensor in the tyre to detect leaks and maintain a safe level of air pressure in your tyres. The LTPW light will illuminate if it detects an abnormal drop in air pressure.

This can happen if your car has been sitting for a long time without being driven or if you have a flat tyre that needs to be replaced.

Oxygen Sensor Malfunction The oxygen sensor monitors your engine's fuel and controls ignition timing based on the amount of oxygen in the exhaust.

If this sensor fails, the engine will continuously misfire and the check engine light will illuminate. The problem will most likely manifest as random misfires or stalling, but if you run out of gas for more than a few seconds, it's time to see a mechanic.

Bad Catalytic Converter The catalytic converter is a component of your car's exhaust system that cleans up harmful emissions. It also serves as an after-treatment device, collecting much of the smog and pollution emitted by cars. If these components fail, your dashboard will display a "Check Engine" light.
