safest question.?
that is easy, cut the Signal. (and ignore the DTC, it should clear ,next power cycle.)
cutting power and ground is bad,
you do know? , that life testing of Assemblies under test
exploit 3 weakness (to simulate Time ,ie: life testing.)
1: power cycling..... hummmmm.
2: heat
3: clock rates. ( fast RPM in this case) high = get hotter and other things bad.
So cut the clock, the output other sensor is low current and it is harmless to
cut it , open and then back closed.
very harmless in fact.
on my car the Sensor driver is an open collector driver transistor
driving the ECU input transistor gate with a series resistor (protection) and
and pull up to 5vdc ECU internal supply.
opening this line is not harmful in an way. see links.
here is my spark page for sidekicks ( 89-98)
I am sure I have no spark
here is the guts of my CMP

we can find these facts on your car too.
it is not hard.
