328i 1998 O2 sensor . . .

i remember an old story that there was an O2 sensor put out by another car maker that was the same as the BMW sensor but alot more cheaper .

dont know if it applies to all E36 but anyone know anything about this ? can my car use it ?

wondering if i can read the check engine fault code by using th gas pedal. but i think that was for older cars.

thanks
