I believe it is called the speed sensor.
Where is the transmisson range sensorat on a 2001mazda626 lx
Mazda 626 does have reverse if its a 5 speed standard H shift then it is 6th gear.
I had the same problem on my 98 Mazda 626 and the O2 sensor was faulty.....
where is the location of all o2 sensars in 99 Mazda 626
on the throttle body
Yes, it has a speed sensor, about $125 online.
On the 2000 626 it is directly under the air filter box.
Mazda 626 frm 1996 doesn't have O2 sensors, have you ECU/PCM inspected, it might have a minor damage.
the ABS sensor is bad.
It's part of the distributor
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626
