Here is what the shop manual says about P0354, work the list from the top down.
Also, as Bmitchell' said the cam/crank position sensors can go bad and create EMI and RFI that messes with the PCM's mind--there is no reliable way the test them with typical tools, so swap 'em out--do the crank sensor first...
