If it's not different than my 92' then it's inside the air flow meter. I belive it to be a little white plastic appendage inside the inlet.
The plastic, black box to the right of the engine is the air intake box. The Intake Air Temperature sensor is plugged in by a rubber grommet on the fender-side of the air box. It comes out with a simple pull.
Near the intake manifold, a small plug and wire sticks out on the pipe.
It should be in the air intake. It look like a light bulb filement most of the time. Look on the air intake box. Also look in the tube coming from the cowl.
There are two fans on a Miata. The main fan is triggered by the coolant temperature sensor, which is at the back of the Miata engine, dead center, just above the transmission. The second fan is triggered when AC is turned on.
At the back of the engine on the coolant outlet that goes to the heater hoses on the firewall.
The camshaft position sensor on a Mazda Miata is changed by disconnecting the wiring harness and unscrewing the sensor using a wrench. The threads can then be cleaned and a new sensor torqued into place.
The 2000 Mazda Miata O2 sensor bank 1 is located on the firewall in the engine compartment. The sensor can be found on the passenger side of the firewall.
It doesn't have one. It uses a flapper type air flow meter which doesn't require an intake air temp measurement.
On a 1999-2005 model Mazda Miata the camshaft position sensor is located on the valve cover towards the rear of the engine (closest to the firewall). It has one 3-pin connector connected to it and one 10mm bolt to remove the sensor
Will a 1992 mazda miata hardtop fit a 2000 mazda miata?
The 2003 Mazda camshaft position in sensor can be found on the back of the left-hand cylinder head. The camshaft position sensor should be labeled as such.
IF that is the Intake Air Temp sensor - It is probably on the throttle body. the other sensor is the TPS throttle position sensor
