Video Description

A check engine light can indicate a broad spectrum of problems with your 1994 Toyota 4Runner. In some cases you need to pull over immediately to prevent damage while in others you merely need to tighten you gas cap next time you stop in order to reset the service engine soon light. The video above shows how to locate the on board diagnostics (OBD) plug on your 1994 4Runner, how to read the trouble codes and how to reset or clear the check engine light using a scanner on your 4Runner.

Intermittent Check Engine Light: If the check engine light on your 1994 4Runner is intermittent, try to take note of the conditions when this happens. For example, does it happen when you accelerating, driving on the highway or does it appear at low speeds? This will help your mechanic evaluate the issue. Steady Check Engine Light: If your check engine light is on every time you operate your 4Runner, you need to have it checked as soon as possible, especially if you notice performance problems or unusual noises. Flashing Check Engine Light: If your check engine light is flashing, stop driving your 4Runner and have it towed to your nearest mechanic - you probably have a very serious problem with your car and you risk ruining your engine by driving it. If you are unsure about what your diagnostic trouble codes mean; have your 4Runner diagnosed by a professional automotive technician.
