It should be located on the back of the motor near the cam sensor. Not near the firewall, but where the trans meets the engine.

Insufficient data from O2 sensor for smog

To review - - after you disconnect the battery you need to drive the vehicle at highway speed for 20 - 50 miles to allow the computer to "re-learn" the data parameters. This means getting the engine up to operating temp and speeds of at least 50 mph.
If the engine does not reach operating temp some of the sensors will not be active yet.

Your guessing an want to replace parts that you have no idea if it will fix your problem . There is no coolant switch , There is a coolant temp. sensor that is a input to the PCM - engine computer . When the PCM see's the temp is over 212 degrees it energizes the low speed cooling fan relay ,when it gets to over 233 degrees it will energize the hi speed cooling relay . Rather then replacing parts , leaning how to read wiring diagrams an using a DVOM - digital volt ohm meter an test the electrical circuits ... Your best bet , take it to a qualified repair shop .

Didnt pass smog i replaced catalytic converter,02 ...

Have a code test done (most larger parts stores do that free) In some cases you may need a shop to put a scanner on it to find specific out of range sensors that may not yet be bad enough to set a code.
I'd also check all vacuum lines and line connections as a small leak can alter the system readings. All the sensors on your car work together and the computer reacts to all the information it receives... Bad info in, bad info out...Only good testing will find the problem.
Primary sensors to pay attention to are the coolant temp sender, MAP sensor, throttle position sensor, manifold air temp sender, mass air flow sensor (if you have one) and the egr valve.and pcv valve (if you have them)
Good testing involves using a digital multi-meter and using instructions for that in chilton or haynes manuals. Replacing parts without testing can get really expensive. (but you have already found that out)
Good luck!

Temp sensor needs to be replaced

this does not mean the sensor is defective, it most likely means the engine thermostat is stuck open and the engine is not running hot enough to satisfy the computers preset temp requirements for minimum eng operating temp.
