the red conector by the fuel pressure regulator (on a VE) is that the colant temp sensor, or temp switch? also what is the black conector right next to it? thanks in advance

 

there's actually TWO coolant temp sensors for the engine. the black one runs the gauge inside the car, the red one feeds the computer information.
disconnect the red one while the engine is running, and the fans will come on about 5 sec later.

 

well i asked cause i pulled the codes and came up with a 13, and a 13 is the engine temp sensor, so is that the same thing as the coolant temp sensor (red conector)? also where is the temperature switch?

 

temp switch? I dunno.

but yes, the red guy is the coolant/engine temp sensor. try cleaning the connections and see what happens. I don't think they're too much to replace, but it's worth trying to clean first.

 

has anybody heard of this i heard you could do some mods to this and get about 15-20 more hp?somebody help

 

yeah... you might be able to.... on a car that actually has an IAT. 3rd gens are OBD-I, not OBD-II.
