Hi I'm Matt and in this video I am showing a Ford Fiesta 1.6 tdci with a P0336 crank sensor range/performance fault code, causing the car to crank and not start.
using an oscilloscope back probed at the crank sensor's signal wire I was able to see that the pick up ring had an extra flat spot on the ring.
this saved stripping down the crank to check timing
the crank pulley with the faulty pick up ring actually looked fine when looking at it by eye.
this one would have been hard to diagnose without an oscilloscope.
thanks for watching.
