What does the orange light mean on a Subaru?
The orange light on a Subaru typically indicates an issue with the vehicle's engine or emissions system. This warning light, also known as the check engine light, is designed to alert the driver to a problem that requires attention.
Understanding the Check Engine Light
The check engine light, or malfunction indicator light (MIL), is a part of a vehicle's on-board diagnostics (OBD) system. This system continuously monitors various components and sensors in the engine and emissions control systems, and the light is triggered when the system detects a problem.
When the check engine light illuminates, it does not necessarily mean there is a serious issue with the vehicle. The light can be triggered by a wide range of problems, from a loose gas cap to a malfunctioning catalytic converter. It is important to have the issue diagnosed and addressed as soon as possible to prevent further damage and ensure the vehicle is running efficiently and safely.
Diagnosing the Problem
To determine the cause of the check engine light, the vehicle's diagnostic system needs to be scanned for trouble codes. This can be done using a diagnostic tool, either at a repair shop or with a consumer-grade OBD2 scanner. The trouble codes provide information about the specific problem that triggered the light, allowing the mechanic to identify and address the issue.
- Common causes of the check engine light include:
- Faulty oxygen sensors
- Malfunctioning catalytic converter
- Loose or damaged gas cap
- Issues with the engine's ignition system
- Problems with the emissions control system
- In some cases, the check engine light may be triggered by a minor issue that can be easily resolved, such as tightening the gas cap or replacing a faulty sensor.
- More serious problems, such as engine or transmission issues, may require more extensive repairs.
It is important to have the check engine light diagnosed and addressed as soon as possible to prevent further damage to the vehicle and ensure it is running safely and efficiently.
