Do different colored temperature sending units have different temperature ranges?
I"ve been noticing with every sr20 swap I do that each one seems to have a different colored temp sending unit on the intake manifold. Like the red/blue/black etc.. and usdm/jdm. Do these have different temperature ranges?

Its not called a temp sendng unit. The red or blue sensor is called a head temp sensor. They do have the same value readings. I have never seen a black head temp sensor in my life on a SR20. The only diffrence between the sensor are the type of plugs they use.
OBDI cars are red, OBDII cars are blue. I have seen Nissan making the OBDIs in blue now from the parts counter. The JDM motors seem to have them all mixed up.

Just to make sure we are talking about the same thing. The sensor you are referring too is the one right by the idle control valve and it is the smaller of the 2 temp sensors right?
Also if we are talking about the smaller of the 2 sensors. Is this the one that controls when the radiator fans are kicked on?

i *** what he is talking about,Its the Coolant Temp Sensor i have a black one and a red one laying around, a 2 pin connector plugs into it and its on the passenger side right next to the AAC

I am talking about the smaller plug not the bigger one.
the small one sends signal to the gauge on the gauge cluster and controls when the fans kick on. i had a JDM too on a B14, temp gauge always read HOT and fans wouldn't switch on, until i changed that frikkin sensor!

Well that doesn't make sense then because my needle on the gauge cluster always reads just a little cold but the fans always kick on at 212*. I think the other plug that goes right next to this one is the one that tells the fans to kick on.. this one is stricktly for the gauge cluster.
So if you are swapping in a jdm sr20 into a b14 which sensor would you need for it to read somewhat accurate on the cluster?

if you swap in a JDM into a B14 use the B14 sensor
