[V8] About Knock Sensors

[David Head]

I was thinking on that. There are 3 wires but there doesn't appear to be
power associated with these. Pin 30 on the ECU is ground for both, 11
and 29 are the inputs. According to the book it detects 'no signal'. You
would need to first try grounding pin 30 and get a o'scope on one of the
inputs to see what one of them puts out.
FYI it retards the timing 16 degrees and enriches the mixture... (11
degrees on a 200 20V).
