Any Ford IAC valve would work, if it fits
IAC Valve is a "control" not a sensor, computer "learns" how much voltage to send to IAC Valve "solenoid" to open it enough for engine to do 700rpm or 1,500rpm, or anywhere in between
And its precise, +/-4rpm usually
Computer has "target RPMs" in a table in memory
say 1,100rpms when coolant is 50deg(cold engine)
and say 750rpms when coolant is at 190deg, fully warmed up
ECT sensor, 5volt 2 wire sensor tells computer engine/coolant temp
Dash board gauge uses a 12volt SENDER for temp, usually 1 wire, so no connection between these
The ECT is an important sensor, it tells computer when to Choke the engine, and how much Choke when engine is cold
All gasoline engines need to be Choked when cold, fuel injection has no Jets so a choke plate couldn't be used, so the computer "chokes" the engine, which means Rich Fuel mix and high idle, based on engine TEMP
