It’s a situation many drivers are familiar with: the car seems to be operating perfectly, and then the check engine light comes on. At Alaska Spring & Performance, providing Anchorage with quality auto repair service, they know this light can come on for a variety of reasons. It’s important to let a professional take a look and perform the necessary check engine light repairs.

Check Engine Light Repair Experts Share 5 Reasons Your Light May Be On

1. Failing Oxygen Sensor

People often neglect their oxygen sensors. This component measures the amount of unburned oxygen in the exhaust system. When it isn’t working properly, you’ll burn more fuel than necessary. If your oxygen sensor isn’t working properly, you may need to replace it.

2. Loose Gas Cap

Sometimes a check engine light comes on to alert you that the gas cap hasn’t formed a full seal. Left unaddressed, you’ll lose a lot of fuel to evaporation. Check the gas cap first when your check engine light turns on.

3. Failing Thermostat

Each car is equipped with a thermostat that serves to regulate the temperature in the engine. However, failing to change coolant on time and driving in extreme temperatures can cause a thermostat to break down quickly.

4. Spark Plug Problems

Spark plugs ignite the fuel and air in the combustion chamber. Over time, they may need to be replaced. If you try to operate a vehicle with faulty spark plugs, you’ll experience decreased fuel economy and power.

5. Faulty Catalytic Converter

A catalytic converter turns harmful carbon monoxide gas into carbon dioxide in your vehicle before it leaves the exhaust system. If it fails, you won’t be able to pass an emissions test until you replace or repair it.
