#1 coolant temp is on the front with the two wire connector, tbh i dont know what that one is ay #2 pic is the oxygen sensor #3 is the throttle position sensor #4 is the closed throttle switch, wat it does i got no fucking idea hey

 

[EVO-00X]

Water Temp, Oxygen sensor (02 sensor), Throttle Position Switch; and throttle closed switch (stupid VR4 thing that tells the ECU the throttle is closed - whatever you do dont touch it as its setup in the right spot and fiddling with it will confuse your ECU into thinking its a Mitsubishi Magna lol )

[brisvr4]

The water temp sensor is on the front of the thermostat housing. The one you have a pic of is the temp sensor for the aircon.

Mate your the best thats just what i need thank you.
any idea what the knock sensor does?

The water temp sensor is on the front of the thermostat housing. The one you have a pic of is the temp sensor for the aircon.

knock sensor detects engine knock/detonation, and will pull engine timing until no knock is present, its a safegaurd for your engine, all turbo engines will have one
