Is there a o2 senser fuse in fuse box if my 97 mazda protege
Has the sensor 4 wires, if yes it has a fuse. The two white wires are for a heater, use a volt meter, should get 12volts across these wires, black wire is an earth and the grey wire is the sensor. If the heater is not working (fuse blown) it will give that code. I have had this fault on a Seat, changed both sensors (180 pounds), then found a broken wire on the back of the fuse box?????????
