There are actually three coolant temperature sensors.
1) The ECT which feeds the ECU. That one's in your picture; the one on the left with the green connector on it.
2) The fan sensor, or more accurately, switch. On the 4 cylinder, it's mounted in the radiator at the bottom on the passenger side.
3) The sensor the gauge uses. Not sure where it is on the 4 cyl, but I *think* it's in your pic, the one next to the green one.
