Do you know what to do if your Hyundai’s check engine light comes on? Many drivers don’t know how to handle this. Fortunately, if you live in Glendora, check engine light service is fast and easy when you visit CardinaleWay Hyundai – Glendora. We’ll examine the different reasons your Hyundai’s check engine light might come on and let you know what to do if it happens.
Your Hyundai’s check engine light doesn’t usually signal an emergency. It may be the result of a minor issue like a faulty gas cap. On the other hand, there are times when it’s serious. If you’re driving and notice your check engine light comes on, bring your car to our service center for CEL testing & diagnosis in Glendora.
A check engine light can either appear flashing or steady. A flashing check engine is an indication of a serious problem that needs attention immediately. When the check engine light flashes, it usually means the ignition system is misfiring. When this happens, unburned fuel is dumped directly into the vehicle’s exhaust system. This can damage the catalytic converter if left uncorrected. If the light is flashing, pull over, shut the car off, and call for roadside assistance.
A check engine light that’s steady indicates a problem that needs your attention. It isn’t urgent. Call the CardinaleWay Hyundai - Glendora Service Center and schedule a service visit.
These are some of the issues that can trigger a steady check engine light:
Faulty Oxygen Sensor
Your Hyundai has an oxygen (O2) sensor that measures the unburned oxygen in the exhaust system. If you don’t replace a bad O2 sensor, the engine will burn too much fuel. You’ll experience a hit in fuel efficiency. A faulty O2 sensor can damage the spark plugs and the catalytic converter.
Bad Catalytic Converter
Your Hyundai’s catalytic converter converts carbon monoxide into carbon dioxide. If the catalytic converter needs to be replaced, your vehicle may fail an emissions test. The engine will generate less power and become less fuel-efficient.
Damaged Mass Airflow Sensor
The mass airflow sensor measures the air inflow of the engine and controls the amount of fuel needed to run the engine. If this part isn’t replaced when it goes bad, it can damage the spark plugs, the catalytic converter and the O2 sensor. You’ll notice a drop in fuel economy and reduced performance.
Worn Spark Plugs
Faulty spark plugs and wires can damage the O2 sensors, the ignition coils and the catalytic converter. You’ll notice the drop in performance, and your car will get fewer miles per gallon.
Loose, Damaged or Missing Gas Cap
Your vehicle’s gas cap creates a seal that prevents gasoline fumes from being released into the air from the fuel system. If you don’t replace a damaged or missing gas cap, it will cause the gasoline to evaporate, and you’ll get less fuel economy.
