I think i can
but at 17 im just going on assumptions and my basic wiring symbol knowledge and i mean basic
.
Question 1
Look at M16/1, it is the Idle Speed Control(ISC), within the ISC is "r2" which is the Actual Throttle Point Sensor(ATPS) and a white wire is connected to it as an output wire i think.
Would that make the white wire the true ATPS wire that informs the ECU of the throttle postion?
From what i can see its an output wire which is good but thats all i know besides "S2" being above it which i thought was the abbreviation for the key ignition switch.
My brain hurts
Question 2
Look at B2/5 it is the Mass Air Flow Sensor(MAF) The yellow and green wire is marked as an output wire with "signal" above it.
Does that mean that it is the wire that informs the ECU of how air is coming in? 
Question 3
Using the diagram of Question 2, please direct your attention to B6/1, it is the cam position sensor. The red and blue wire goes elsewhere to some kind of circuit and the brown and green wire is ground, that leaves the yellow and gray wire. It is the only output wire and has a cool abbrev. "CMP" so......
Is the yellow and gray wire the output for cam sensor that informs the ECU of the cams position and engine speed?
