anyone who can tell kung yung switch ba o sensor yung isa na single contact na nasa cylinder head ng 4d56. the double contact is the temperature sender while yung part in question have never been tapped into the circuit of the vehicle since acquisition. ngayon ko lang napansin. its location is just beside the engine hanger.

some say it's a temp sensor for the fuel system during cold starts, temp sensor for the O/D of the A/T, etc.

did a resistance test myself. zero ohms (ON) when cold, XXX ohms when hot (forgot the reading, sorry). i am planning to install a thermo switch connected with the aux fan in place of this sensor. my auxiliary fan is tapped to the A/C at present.
