it's all moot now, car runs
its not wise to hot wire any ECU, (means putting 12vcd on a pin you have no idea what's on the other end, in most cases , no one does, there is no schematics on this) using and incandescent lamp as the current limit is crazy, it can be 250mA or more, for the lamp)
how ever tools can be made that can generate pulses, that are safe, a 0 to 4v pulse is safe, and current limited to say 10mA. (max TTL levels and currents)
the tool may work or not, that is because the ECU on most cars, (for sure newer) fail to accept signals out of time. and for sure weak levels, on all.
How the inputs are connected on the ECU side, for a CKP is unknown by anyone. (for sure on potted ECUs.... super hard to see)
it can be 1pin to ground and 2nd to the amp .
or the amp can be a differential amp and no grounds at all on the input. full floating inputs.
nor is that HV spark test, every step there he did is irresponsible. (wrong tool and holding it. like that)
there are better videos. by ASE masters.
