Check that the hoses to and from the air cleaner haven't got a kink or are going soft. This will cause the hose to suck in on itself under heavy acceleration (2.2l deisel hiluxes did this) and cause a restriction, loss of power and the warning light.
Do you have a snorkel fitted? Some have a dry foam filter jammed in them that most people don't know about untill they clog up.
Just a thought.

The light is to indicate a restriction...so somewhere you are restricting the intake air before the sensor.
The Snorkel may be too small for the vehicle and apart from adding another I guess you will live with it.
Is the filter element original? Have you changed to foam? You said its clean but it may be too restrictive from the OEM one.
As others have said look for soft hoses etc or places where they might have kinked and cause a restriction.

All the best

check the hoses from the switch to the top and bottom of the air barrel,make sure they are connected and not kinked.is the performance down?if it isnt maybe the switch is faulty only.food for thought. cheers Paul

Maybe they're not all the same, but my 105 (1HZ motor) has two sensor rubber lines to the air cleaner, sensing only across the air filter element, running back to a pressure switch. Therefore, if the light is coming on, it means that the air cleaner is stuffed/blocked, the sensor lines are kinked, blocked or disconnected, or there is problem with the pressure switch itself. Since the sensor measures pressure drop across the filter, blockages upstream (such as a blocked snorkel) will not cause a higher pressure drop across the element - in fact, it will do quite the opposite.
