What Does the Check Engine Light Mean?
The check engine light is a warning indicator on the dashboard that alerts the driver that there is a problem with the engine or its related components. It can be caused by a wide range of issues, from minor problems such as a loose gas cap to major issues like engine failure. When the check engine light turns on, it is important to take it seriously and address the issue as soon as possible.
Common Causes of Check Engine Light in 2015 Toyota RAV4
There are several common causes of the check engine light turning on in the 2015 Toyota RAV4. Some of the most common causes include:
1. Oxygen Sensor Malfunction
The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust system. If it malfunctions, it can cause the engine to run rich or lean, which can lead to decreased fuel efficiency and increased emissions.
