Honda Part # for ECT Sensor (Not coolant temperature sensor on thermostat)

Hey all. Anyone have the Honda part number for the ECT sensor under the throttle body? I am getting 7 flashes on my FI light and the bike is really hard to start when cold. I read the service manual an it says it is the ECT sensor but I can't find it online and when I call the local Honda Shop here all they show is the coolant temperature sensor that is located on the thermostat housing. Any help is appreciated.

Thanks Makis. I was looking for clarification because it seems like from what I read there were two of them. Found the other one in the front left radiator.

That switch on the left rad is to engage the fan. It has a specific temp point that it connects the fan's ground line and the fan starts to work. Once the coolant temp drops below that point, that switch disconnects the ground line and the fan stops.
In SP2 models both fans are engaged through the ECU so there isn't such a switch on SP2's radiators.
