Those sensors are actually connected to your air intake pipe just after your air filter. They're just plug and play sensors.

SOURCE: location of mass air flow sensor
The sensor is mounted on the throttle body between the air cleaner assembly and the air cleaner outlet tube.

The coolant temperature switch and fan control switch are located sie by side, mounted in the steel portion of the heater hose that runs from the thermostat housing to the firewall, it is underneath the air intake tube and the ignition coil pack, mounted to the back of the cylinder head. Either drain out some coolant or be very quick, and you can unplug and unscrew each switch from the hose and replace it with a new one. Make sure the engine is cold. After replacing make sure to check the coolant level add as neccessary. The single wire connector switch is for the guage, and the other is for fan control. Hope this helps, let me know.

The mass airflow SENSOR uses a small platinum wire with a current run through it to determine the volume of air flowing in.(More air makes the wire cooler,less air makes it hotter).After a while,deposits will build up on the wire,affecting the reading.(or,it may also get a high resistance open causing erratic operation).Every time I have seen a MAF sensor fail,unplugging it will force the PCM to substitute a value,which will make it driveable(it won't run very good,though).This is more effective on the cases where the wire is broken/breaking.If unplugging it somewhat cures your problem(you didn't say what the symptoms were),then try it.(make sure the new sensor goes in with THE ARROW FACING TOWARDS THE ENGINE(DIRECTION OF AIRFLOW!).(I have seen numerous clowns on car shows put it the other way and spend a ridiculous amount of time trying to diagnose it).
