the yellow warning light on my toyota estima displayed by the shape of a engine.comes on at40 mph and goes of at 50 mph.can you advise to what the problem might be thanks.
Under the left front seat is a small black rectangle flip top box, open the lid and bridge te1 and e1 turn as shown under the lid. ignition switch on and count the engine check light flashes, slow flashes are counted in tens and fast flashes are in digits e.g. two slow and three fast would be 23. there could be more than one code and they will come up in numerical order. check three times as the system keeps repeating. then search for code details
