Exclamation P-o351

It say's it's a Ignition coil A Primary/Secondary Malfunktion.
So if I replace the coil on #1 spark plug then that should clear the engine light, right?
That is the only code it showed me twice so that's primaty and secoundary so just replace it?
Owe and it's not my truck for a change...lol
It's an econoline van with a 5.4ltr.
