2. Common Subaru Indicator Lights and Their Meanings

What are the most frequent Subaru indicator lights drivers encounter, and what should you do when they appear? Here’s a detailed breakdown of some of the most common Subaru indicator lights, their potential causes, and recommended actions:

2.1. Check Engine Light

2.1.1. What does it mean?

The check engine light, often represented by an engine symbol, is one of the most common and often misunderstood Subaru indicator lights. According to the Environmental Protection Agency (EPA), this light indicates an issue that could affect your vehicle’s emissions system.

2.1.2. Potential Causes:

• Loose Gas Cap: This is often the simplest fix. Ensure your gas cap is tightened properly.
• Faulty Oxygen Sensor: The oxygen sensor monitors the amount of oxygen in the exhaust stream. A failing sensor can affect fuel economy and emissions.
• Catalytic Converter Problems: The catalytic converter reduces harmful emissions. If it’s not functioning correctly, it can trigger the check engine light.
• Spark Plug or Ignition Coil Issues: Problems with spark plugs or ignition coils can lead to misfires and trigger the light.
• Mass Airflow Sensor (MAF) Issues: The MAF sensor measures the amount of air entering the engine. A faulty sensor can cause performance problems.

2.1.3. Recommended Actions:

• Solid Light: If the light is solid, it indicates a non-critical issue. While you can continue driving, it’s recommended to have your vehicle inspected by a certified mechanic as soon as possible.
• Flashing Light: A flashing check engine light indicates a more serious problem that could potentially damage your engine. In this case, you should stop driving as soon as it’s safe to do so and have your vehicle towed to a repair shop.
• Diagnostic Tools: Consider using an OBD-II scanner to read the error codes and get a better understanding of the problem. CAR-TOOL.EDU.VN offers a range of diagnostic tools to help you with this process.

Subaru Check Engine Light

2.2. Oil Pressure Warning Light

2.2.1. What does it mean?

The oil pressure warning light, usually shaped like an oil can, indicates that the oil pressure in your engine is too low. According to a study by the American Automobile Association (AAA), maintaining proper oil levels and pressure is crucial for engine longevity.

2.2.2. Potential Causes:

• Low Oil Level: This is the most common cause. Check your oil level using the dipstick.
• Oil Pump Failure: The oil pump circulates oil throughout the engine. If it fails, the engine won’t receive adequate lubrication.
• Oil Leak: A leak in the oil system can cause a drop in pressure.
• Clogged Oil Filter: A clogged filter can restrict oil flow and reduce pressure.
• Faulty Oil Pressure Sensor: In some cases, the sensor itself may be faulty, giving a false reading.

2.2.3. Recommended Actions:

• Stop Driving Immediately: Driving with low oil pressure can cause severe engine damage. Stop driving as soon as it’s safe to do so.
• Check Oil Level: Use the dipstick to check the oil level. If it’s low, add oil to the recommended level.
• Inspect for Leaks: Look for any signs of oil leaks under the vehicle or around the engine.
• Seek Professional Help: If the oil level is correct and there are no obvious leaks, have your vehicle inspected by a mechanic to diagnose the cause of the low oil pressure.
