You test the CKP sensor by using a diagnostic tool to verify crankshaft signal.
Old school - remove sensor - with wire connector hooked up - turn key on - wave sensor back and forth just over a metal surface - should hear ignition spark from one of the coils. For real !
However the correct scan tool is indeed invaluable.
