Hi, cable routing is unknown to me - sorry. signals go from sensor below intake manifold to ICM control module in box (closest to engine in my car) behind dtc a/b terminals.
#A22/23 KS1 signal/ground, #24/25 KS2 signal/ground.
#A connector diconnected: ground to engine graound 0ohm, signal to engine ground 1Mohm. to check the cabling for breaks and short cuts you should be able to disconnect also the sernsor end of cabling to measure.
running over 3500rpm with load KS signal should be measurable (2-7?) but here I'm on thin ice.
