Why Is My Hyundai Check Engine Light Active?

why is my hyundai check engine light active?

Bob Howard Hyundai invites you to find out why your Hyundai check engine light is active.

The check engine warning light warns drivers of future engine problems or complete failure. Your check engine warning light might come on because of many reasons. It could be small things like sensor failure, an alert to perform maintenance (such as an oil change), or even warning of potentially significant problems that could contribute to engine failure. So, even if the check engine warning light turns on, it might not be a complete disaster. However, if and when your check engine warning light does come on, we suggest bringing it to us for a full inspection as quickly as possible. Even if nothing seems broken, having it diagnosed accurately can be the difference between a cheap repair and having to replace the engine.

Old Gas Cap

Loose Gas Cap

Something as silly as not replacing the gas cap or not tightening it completely could easily cause a check engine warning light. The vehicle’s gas cap might need to be replaced during your vehicle ownership. Gas caps may last only 50,000 miles. We highly recommend genuine OEM replacement parts if it is time to replace your gas cap. Parts from DIY stores will work in an emergency, but nothing beats OEM parts.

Oxygen Sensors in The Car are Failing

Bad O2 Sensors

Several sensors give info to the car’s engine to help it run efficiently. However, bad readings from components like the MAF sensor or the O2 sensors can cause a check engine warning light to come on. If the vehicle is running like normal, a faulty O2 sensor is the most likely reason. This might mean that your vehicle is running normally, but because the engine is not receiving the information, it triggers the warning. Even if your vehicle feels fine, you should get it checked out immediately to rule out any potential more significant issues.

Spark Plugs in Your Vehicle are Faulty

Spark Plugs in Your Vehicle are Bad

Spark plugs are essential to the efficiency of your vehicle’s engine. As the name indicates, spark plugs provide a small spark of electricity, which then ignites the fuel and causes the engine to run. Spark plugs have accurate measurements for peak performance, and if the spark plug setup is too large, it could cause a check engine warning light. Some symptoms of faulty spark plugs include diminished fuel efficiency, slower acceleration, and an engine that just does not run smoothly.
