the 5EFE engine is a non-interference type engine. no valve/piston damage (from a simple belt failure anyway).
frankly, i've never seen an engine with a belt break a tooth. unless the idlers were tossed. chain yes, belt, no.....
however,
a broken tooth on a sprocket won't cause the sensor to not send a signal. just an erratic one. the ecu will see it as incorrect/incompatible info and trigger ecu limp mode operations and kick out a trouble code that will point to the sensor. that doesn't mean the sensor is *necessarily* bad. just that the info isn't valid for correct operation. your vehicle wouldn't run as the valve/cam timing would constantly change through out the 360 crank degree range.
a broken tooth on the sprocket is easy to see. there will be gap where the tooth was. so if there's no gap, you have the wrong sprocket.
if it is missing a tooth. a belt isn't going to break it. something else very serious is going on in the timing gear area.
you've got to have some codes stored on this. pull 'em.
