SOURCE: fuse box on 94 mazda b3000

Try testing the brake switch (it is behind the brake pedal) for 12V and continuity between wires when engaged. You can also try checking the brake light relay. It is located on the fuse block.

i hope this helps

Is there a knock senser on a 1994 Mazda b3000. The code flashes 331


The engine in your B3000 may not be the original; I find no listing for that code, only these:

Mazda Trouble Codes and Retrieval Method OBD1

Look down the page for the only codes I found listed and they are all OBD1 prior to 1995.
