got fault code 21 today (primary ignition fault) and was needing some help figuring out what would cause it

i replaced these ignition parts about a year ago, and this is the first time if had the code,

roter arm
dizzy & dizzy cap
HT leads
ignition coil
spark plugs (correct heat & gap)
ignition coil

is the any other part in the ignition system that could cause this other than the parts iv replaced

thanks
 
Have you done any work to the car recently?

Is it running ok? If it is i'd clear the fault then see if it reappears again.

It could also be a connector plug or wiring fault.
