Hayden Lake Check Engine Light
Your car’s check engine light is an important feature that helps to keep the vehicle running properly and safely. Many drivers don’t know what actions to take when their car’s check engine light comes on. In this article, we’ll explain why the light may come on and let you know what to do if it does. If you live in or near Hayden Lake, check engine light service is nearby when you visit Knudtsen Chevrolet in Post Falls.
When the check engine light comes on, it’s usually not an emergency, so there’s no reason to panic. But there are some instances where the check engine light is alerting you to a serious situation that must be attended to immediately. If your car’s check engine light comes on, bring it to the Knudtsen Chevrolet Service Center for CEL diagnosis & testing near Hayden Lake.
Flashing Check Engine Light
A flashing check engine light indicates a serious problem that needs immediate attention. When the check engine light is flashing, it’s usually a warning that your car’s ignition system is misfiring. When this happens, unburned fuel is dumped into the exhaust system, which will damage the catalytic converter. If the check engine light is flashing, pull your car over, turn it off, and call for roadside assistance.
Steady Check Engine Light
If the check engine light is steady, there’s a problem that should be addressed as soon as possible. If you notice a steady light, contact the Knudtsen Chevrolet Service Center and make an appointment for check engine light service. A steady check engine light can be triggered by several different issues.
These are some of the problems that will cause a steady check engine light to come on.
Faulty Oxygen Sensor
Your vehicle has an oxygen (O2) sensor that measures the level of unburned oxygen in the exhaust system. If this sensor is damaged, the engine will burn more fuel, and you’ll notice a decline in fuel economy. If this isn’t repaired, it could damage the spark plugs and the catalytic converter.
Bad Mass Airflow Sensor
The mass airflow sensor measures the engine’s air inflow and controls the amount of fuel needed to run the engine. A defective airflow sensor can damage the O2 sensor, the spark plugs and the catalytic converter. You’re also likely to see a decline in fuel economy.
Defective Catalytic Converter
The catalytic converter converts carbon monoxide into carbon dioxide. If the catalytic converter becomes damaged, there will be a loss of performance and fuel economy. Additionally, your car may fail an emissions test.
Worn Spark Plugs
Worn spark plugs and wires can cause damage to the ignition coils, catalytic converter and O2 sensor. Performance and fuel economy will take a hit.
Loose, Damaged or Missing Gas Cap
Your car’s gas cap prevents gasoline fumes from escaping into the atmosphere. A loose gas cap can be tightened. A damaged or missing gas cap should be replaced. If fuel evaporates due to a missing, loose or damaged gas cap, fuel economy will suffer.
