Check engine light flashes during high reving - Toyota Yaris Forums

A friend of mine has a Mustang. When he gets near the rev limiter, the engine light flashes. If you are too close for too long, at will stay on and if you hit the rev limiter, engine light stays on.

His Dad has got some type of diagnostic head made by snapon. It didn't show the code (rev limiter) even with the engine light still on. When he took it in, he was warned about abusing the engine and further abuse, may void the warranty. It seems that those type of codes that may report abuse are secret and you must have the right diagnostic head to read them.

I can not confirm or deny.. This is just what I was told.
