Only if it's not a multiple of the number of cylinders/2.
IE. you have an integer number of teeth between each firing.

Running some numbers on the Audi 5 cyl engines:

135 teeth - so 270 per cycle, 72 between each cyl firing.
Resolution is 360/135 degrees - or it would be if they
didn't use BOTH edges of the tooth signal - giving a resolution
of 360/270 or 1.33 degrees.
