am a little lost were to find these on my c20xe,can any one help?maybe post some pics

ECT = Engine Coolant Temperature sensor
IAT = Intake Air Temperature
CTP = Closed Throttle Position --------- could this be TPS related?
ECM = Engine Control Module

 

[Rusty]

ECT: On the thermostat housing.
IAT: Only for Motronic 2.8, between the airbox and the AFM
CTP: Must be the TPS, which is on the throttle body.
ECM: Behind the drivers kick panel

differrent engine but mostly the same position

Green Arrow = ECT
Yellow Dot = IAT
CTP is the closed position of the TPS = Red Dot

PS just noticed my red dot is wrongy placed lol look behind the throttle body, there is a small black box, about half the size of a 10 ciggy pack ,, this is the TPS
