If your car’s check engine light comes on while you’re driving, you should take notice, but it’s not a reason to panic. In most cases, you can continue driving until you can bring your vehicle to a service center. If you live in Liberty Lake, check engine light service is nearby. The Knudtsen Chevrolet Service Department in Post Falls will diagnose the cause of the check engine light and fix any problems.
There are two types of engine light indicators: steady and flashing. If you notice a steady check engine light in Liberty Lake, bring your vehicle to the Knudtsen Chevrolet Service Center. If the light is flashing, it’s usually an indication of a problem that needs immediate attention.
A steady check engine light means there’s a problem, but it’s not an emergency. If your car’s check engine light comes on and it’s steady, contact the Knudtsen Chevrolet Service Center and make a service appointment. It could be an indication that the vehicle’s catalytic converter is bad, the oxygen sensor is faulty, the airflow sensor is no longer working properly, the spark plugs need replacement or the gas cap is damaged.
These are some issues that will cause a steady check engine light to come on.
Faulty Catalytic Converter: Your car’s catalytic converter is an important part that converts toxic gases in the exhaust into less harmful components. If your vehicle’s catalytic converter is no longer functioning correctly, you’ll notice decreased fuel economy and a reduction in power. If the catalytic converter malfunctions, your vehicle may not pass its next emissions test.
Defective Oxygen Sensor: Your vehicle’s oxygen (O2) sensor is another essential part of the emissions system. This sensor measures the oxygen content of the exhaust gases and sends the information to the engine computer. When the O2 sensor fails, it causes a drop in fuel efficiency, loss of power, black smoke from the tailpipe, hesitation or stalling, or rough idling. It may also cause your car to fail an emissions test.
Bad Mass Airflow Sensor: The mass airflow sensor is part of the electronic fuel injection system. It calculates the amount of air that enters the engine. If this part is damaged, you may notice black smoke coming from the tailpipe, or the engine running rough or backfiring. You may also see a drop in fuel economy.
Worn Spark Plugs: Your car’s spark plugs are very important. Spark plugs supply the ignition source that ignites the fuel and drives the pistons. When the spark plugs are bad, the car may not run at all. Signs of malfunctioning spark plugs include a drop in fuel economy, slow acceleration and a misfiring engine.
Loose, Damaged or Missing Gas Cap: Your car’s gas cap keeps the fumes from the gasoline from escaping. If the cap is loose, you can tighten it. A damaged or missing gas cap must be replaced. If the gas evaporates due to a problem with the gas cap, you’ll notice decreased fuel economy.
If your check engine light comes on and it’s flashing, it means there’s a serious problem that needs immediate attention. This usually indicates the car’s ignition system is misfiring. When this happens, unburned fuel is dumped directly into the exhaust system, which will damage the catalytic converter. If the check engine light is flashing, pull over, turn off the ignition, and call for roadside assistance.
