Go to the right and step back and forth until the far right pitfall is closed and you're standing in the middle.
Then go back and forth between the left and middle until the middle pitfall is open, the left pitfall is closed and you're standing on the left.
Step onto the closed pitfall, then back on the left pressure plate, onto the middle pressure plate and onto the left pressure plate.
All the pifalls should be closed and you should be able to advance.

Sometimes you have to step forward before stepping back.

If it doesn't help you:

Let's take the current combinaison:
456
123
where 456 are the pits and 123 are the pressure plates (pressure plate 1 opens/closes the pit 4, etc.)
You start from 1.

The sequence is 1-4(4 is closed since you pressed the pressure plate 1)-1-2-1
And there you go, all pits are closed.
