I just changed it (the front O2 sensor) on my 2003 Miata. I believe yours will be the same. First, you will need an O2 sensor wrench (about $10 from Advance Auto Parts). Don't waste your time trying to remove it without one. Then follow these steps:
1. Warm the engine, and let it cool to the point you can safely touch the sensor and exhaust pipe.
2. Jack up drivers side front wheel, and put a jack stand under the frame.
3. Remove wheel. (I put the wheel with a piece of 2 x 6 on top of it to the rear of the jack point for added safety.)
4. Apply Liquid Wrench or equivalent to the sensor-exhaust connection - wait at least five minutes.
5. You may still need to add a piece of pipe (or 1/2" spark plug socket with 8" extension worked for me) to your 3/8" ratchet wrench handle to get enough leverage to break the sensor free.
6. If you replace with a universal type O2 sensor (I used a Bosch 15733 sensor from Amazon at $45.41), you will need to reuse your old electrical connector by splicing it in. The Bosch unit I used has a special connector assembly for doing this. It is a bit tedious to assemble but seems very solid. Just follow the instructions. With the Bosch sensor, the two white and two black wires individually (two connections) go together and the remaining the single black and blue and single grey and white wires connect.
7. Reassemble.
You will need to remove the positive battery terminal to clear the check engine light.
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.
Near the intake manifold, a small plug and wire sticks out on the pipe.
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.
There is no Distributor cap or rotor in a 91 Mazda Miata. All years of the Miata use electronic computer controlled ignition systems.
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
same as the 1994

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.
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.
