RIghto, im struggling anyone got any ideas on what these sensors are on the intake. Im starting to wire up this link computer, need to know the exactly what the sensors are
Orange - square TPS? (butterfly closed)
Yellow - ????
Blue - something to do with choke/idle (butterfly open)
Red - Stepper motor
Cheers Phil

they look like traction control parts

cant find the one with the TCS system though... hmm
There is IAC, TPS and Sub TPS... maybe thats it...

aren't those things in red the throttle and kick down cables? or at least where they would be normally?

Yeah they are, actually meaning the motor? or sensor just to the side of it it?
IAC? is that idle air control?

Yes idle air control, its a stepper motor.
is the sensor attached to the throttle body? or the top of the manifold? can't really see from that photo.

attached to the throttle body, looks like its attached to the first butterfly, so my guess is that it's the stepper motor, no idea what the other 2 sensors are, according to those links it might be a iac valve, but there is no mention of the one in the blue box, but the shaft from what i think is the stepper motor to the butterfly in the intake then to the last sensor in the blue box, how do u tell that its one with a afm and not a map?

because it has traction control. It's possible that some of those sensors are to do with the TCS... I'll see if I can get a camera and take a photo of my throttle body, should be able to work out which are IAC and TPS as they will be the same... also you have a hose missing from the top of the throttle body...
