What is a check engine light?

The Check Engine Light, also known as the Malfunction Indicator Lamp (MIL), is an essential component of your Acura’s onboard diagnostic system. It is represented by an engine-shaped symbol and is usually located on the dashboard of your vehicle. When this light illuminates, it indicates that the car’s Engine Control Module (ECM) has detected a problem or potential problem with the engine or emissions control system.

Significance of Check Engine Light

The check engine light plays an important role in modern vehicles by alerting drivers to potential problems that could affect engine performance, emissions, or overall vehicle safety. Ignoring the light or dismissing it as a minor problem can lead to more significant complications in the long run.

How does the check engine light work in Acura vehicles?

In Acura vehicles, the check engine light is connected to a network of sensors that continuously monitor various components of the engine and emissions system. When the sensor detects a problem or anomaly, it sends a signal to the ECM. The ECM, in turn, activates the check engine light to notify the driver that a diagnostic trouble code (DTC) has been stored.

Is it safe to drive with the check engine light on?

Seeing the check engine light can be annoying, but in some cases, it may be safe to drive a short distance. However, this issue needs to be resolved as soon as possible. If the check engine light is flashing, it indicates a serious problem that needs immediate attention. In such cases, it is best to pull over, turn off the engine, and seek professional assistance.

How to Check and Reset an Acura Check Engine Light

5.1 Using the OBD-II Scanner

An OBD-II scanner is a handy tool that allows you to read error codes stored in your car’s computer. After identifying the code, you can investigate the potential problem or seek advice from a mechanic. After fixing the problem, the OBD-II scanner may also reset the check engine light.

5.2 Disconnecting the Battery

Disconnecting the vehicle’s battery for a few minutes can also reset the check engine light. However, keep in mind that this method may also reset other settings in your vehicle, such as radio presets or the clock.

5.3 Fixing the underlying problem

The most effective way to turn off the check engine light is to address the underlying problem causing it. If you are satisfied with basic car repairs, you can try to fix the problem yourself. Otherwise, it’s best to take your Acura to a qualified mechanic.

When should you seek professional help?

While some minor problems can be solved with DIY methods, there are instances when professional help is necessary. If you experience any of the following situations, it’s time to visit a mechanic:

  • Check engine light is flashing.
  • The car is showing signs of low performance or stalling.
  • You notice strange sounds or smells coming from the engine.
  • You are not sure about the problem or how to fix it.
  • Precautions to Avoid Check Engine


Finally, the check engine light in your Acura is an important indicator that should never be ignored. It acts as a warning system that keeps you informed of potential problems with your vehicle’s engine and exhaust system. By understanding the possible causes behind this light and taking immediate action, you can prevent further damage and ensure the longevity of your Acura.

Remember to be proactive with regular maintenance and address any problems indicated by the check engine light immediately. By doing so, you will be able to enjoy a smoother and more hassle-free driving experience.
