Most knock sensors are located in the block on the firewall side. Should be the only sensor with two wires in the block. It will also have a camshaft position sensor as well.
Hope that helps. I am not educated on Mazda engines.
how to change speedometer sensor on mazda millenia 2000 2.3 v6

On the transmission output shaft housing on the side closest to the firewall.

2.5L V-6 Mazda Millenia engine is a non-interference engine. If your timing belt pops, you will not damage your valves, like I did in my Diamante
The bank 2 is located on the driver side of the engine on the Mazda Tribute. The Sensor 2 is located after the catalytic converter.
29's here i have a 97 Mazda millenia 2.5 and have had the knock sensor replaced. all the Mazda 2.5 motors 95-02 are the same so i can tell you that its located in the center of the engine only accessible from the top of the motor underneath the intake and fuel rails (which have to be removed in order access the sensor). the gasket for the intake can not be reused and must be replaced. this a repair that a standard mechanic should be able to perform. hope this helps. It is underneath the supercharger support bracket on the 2.3L.
The S denotes the 2.3 Supercharged engine one the Mazda millenia (rather than the regular 2.5)
Depends on Which Year and Which Engine (2.3 or 2.5) My 99 2.5L has 4 o2 PLUS a knock sensor
