Name That Intake Sensor
#2
#1 EAC1385.
The one closest to the radiator is the thermo time switch, this is only operational during while the starter circuit is engaged. It checks if you are starting a cold engine or not and allows the cold start injector to supply extra fuel if needed. These are not easy to find any more.
#2 071-241 (Moss Motors) Temperature Transmitter (Temp Gauge)
The second one back with the single spade connector is the sender for the coolant temperature gauge on the dash, these are easy and cheap to replace.
#3 EAC3927. Coolant Sensor.
The third one back is the coolant temperature sensor for the electronic fuel injection, its job is to tell the ECU to allow a richer mix if the engine is not fully warmed up, at about 180 degrees F. This has little to no effect on the fuel mixture. This is cheap and easy to replace. If you are running rich and you think it might be this sender then your engine should only be showing symptoms of a rich mixture while warming up.
#4 EAC3762. Thermal Switch.
The fourth one back is a sender for the emissions control system, I've heard that it may have something to do with the AC?
