What to Do If Your Mazda Check Engine Light Comes On
If your Mazda check engine light has come on, it could mean you have to do some maintenance on your car. To keep it running smoothly, you need to make sure that the spark plugs, Oxygen sensor, and fuel system are in good condition. Also, you need to make sure that you always idle your car for a few seconds before you shut it off, so that you can avoid damaging it.
Spark plugs
If you are seeing a check engine light on your Mazda, it may be due to a faulty spark plug. This is not a problem you want to ignore. It can cause a misfiring engine that will make the car run poorly.
The spark plugs are an essential part of your vehicle’s electrical system. They serve as the ignition source for each piston. When they go out, the engine will misfire and have a hard time generating enough power to drive your car.
Spark plugs should be replaced every 30,000 miles. In older vehicles, they should be changed more often. You can purchase spark plugs online and it will only cost you around $20 per spark plug.
When you turn on the ignition, the spark plugs are supposed to create a hot spark to start the car. But worn or damaged spark plugs struggle to ignite the fuel-air mixture.
Fuel system
If you have a Mazda check engine light on your vehicle, it may be a sign of an issue with your fuel system. A properly functioning fuel system is a key part of maintaining a safe and efficient driving experience.
The fuel system of a modern vehicle is designed to maximize efficiency while keeping a safe amount of gas and oil in your tank. In addition, it is equipped with an onboard computer that monitors several major operating systems to ensure that your vehicle performs as efficiently as possible.

Several factors can cause a check engine light to illuminate. For instance, if you have a loose gas cap or a dirty or faulty fuel injector, you can expect the light to turn on.
Oxygen sensor
If you’re a Mazda3 owner, you may have noticed the check engine light coming on. This is a warning that your vehicle needs repair. However, you may be unsure of what the problem is. Luckily, you can use an OBD2 scanner to determine the cause of your check engine light.
The O2 sensor is a vital component of your vehicle’s emissions control system. It measures the oxygen levels in the exhaust gasses and feeds the data to the engine management computer. Performing regular maintenance on the O2 sensor is important to ensuring that it continues to function properly.
A bad oxygen sensor can have a serious impact on your car’s performance and fuel economy. In addition, it can damage your catalytic converter.
Idle for 30 seconds before coming to a complete stop to avoid damage
One of the more common misconceptions about engines is that they should be idling before you drive. While it’s true that some modern engines are designed to idle 100%, idling isn’t recommended. When you do it, you can burn up your battery, cause your engine to overheat, and damage your engine’s thermostat and fan belt. It’s not the smartest thing to do, and idling isn’t the best for the environment either.
If you’re in the market for a new car, make sure it’s equipped with a turbo waste gate that allows it to idle for a few minutes. Idling for a few minutes will help warm up your engine.

A idling car also produces fine particulates that are harmful to the environment. Some states have laws limiting idling to 30 seconds or less. However, idling your vehicle isn’t the only way to save energy.
Is it time to perform maintenance?
If you own a Mazda, it’s important to keep it maintained. It will ensure your vehicle’s safety and reliability. You can check your owner’s manual for the recommended maintenance intervals.
Generally, you should have an oil change every 7,500 miles. This is to ensure that the motor oil lubricates the metal parts and prevents it from overheating. Performing this maintenance on time will keep your vehicle running smoothly and save you money on costly repairs.
Other maintenance procedures include inspecting the brake fluid levels and checking the disc brakes. Technicians also inspect the engine coolant. They may need to replace spark plugs or other components.
Mazda has a maintenance schedule based on the number of miles you drive. In addition to the mileage, you also need to consider driving conditions. Roads that are sloppy, dirty, and rough can affect the life of your vehicle.
