Will the check engine light reset itself?

The check engine light on your Toyota RAV4 will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Toyota RAV4 light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in so the light and code can be double-checked and reset.

But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your Toyota RAV4 checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Toyota RAV4's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Toyota auto repair mechanics. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.

The O2 sensor sends data to the vehicle’s onboard computer to represent the decent assortment of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.
  • One of the most current and frequent cause is that your Toyota RAV4 gas cap is loose, damaged or missing. The gas cap for your Toyota RAV4 serves multiple purposes.
