That light that gets us worried, the Subaru Check Engine Light Flashing vs Solid – the Difference? Seeing your Subaru’s check engine light turn on can be unsettling. It’s a warning sign that something isn’t right under the hood, but not all check engine lights mean the same thing. If you’ve noticed the light is flashing instead of staying solid, it’s crucial to understand the difference. One could mean a minor issue, while the other could indicate an urgent problem requiring immediate attention.
At Automotive Instincts, we specialize in diagnosing and repairing Subaru vehicles, ensuring your car runs smoothly and reliably. Here’s what you need to know about your check engine light and what to do next.
Solid Check Engine Light: What It Means
If your check engine light is solid and not flashing, it usually indicates a problem that needs attention but isn’t an immediate emergency. Some of the most common causes of a steady check engine light include:
Loose or Faulty Gas Cap
A simple but often overlooked issue. If your gas cap isn’t tightened properly, it can cause a leak in the fuel system, triggering the light.
Oxygen Sensor Failure
The oxygen sensor monitors fuel efficiency and emissions. A failing sensor can reduce gas mileage and eventually harm the catalytic converter.
Spark Plug or Ignition Coil Issues
Worn-out spark plugs can lead to poor engine performance, rough idling, and reduced fuel efficiency.
Mass Airflow Sensor Malfunction
This sensor measures the air entering the engine and helps regulate fuel injection. If it fails, it can cause rough driving conditions and poor fuel economy.
While a steady check engine light doesn’t require you to stop driving immediately, it’s best to schedule a Subaru Auto Repair service as soon as possible. Ignoring it for too long can lead to more severe damage and costly repairs.
Flashing Check Engine Light: A Sign of Urgent Trouble
A flashing check engine light is a far more serious issue. It typically signals an engine misfire, which can cause unburned fuel to enter the exhaust system. This can quickly damage the catalytic converter, leading to expensive repairs. Common reasons your Subaru’s check engine light may be flashing include:
Severe Engine Misfires
This happens when fuel isn’t burning properly in one or more cylinders, leading to rough performance, shaking, and potential engine damage.
Catalytic Converter Failure
Ignoring misfires for too long can overheat and destroy the catalytic converter, a costly component that helps control emissions.
Fuel Injector Problems
If fuel injectors are clogged or malfunctioning, they can cause lean or rich fuel mixtures, impacting performance.
If your Subaru’s check engine light is flashing, pull over immediately and avoid driving further. Continuing to drive can cause irreversible engine damage. Contact a trusted Subaru specialist right away for diagnostics and repairs.
