1996. Which color wires go where?


There should have been an instruction sheet in the box with the sensor. If not, you may have to go back to the store and ask for one.
Most sensor brands are different.

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?????????

Po141 heater circuit , bank 1 sensor 2


to check this the 02 sensor closest to the engine has a 4 wire connector, key off engine off. disconnect the sensor and on the sensor side connector thre are 2 white wires and 2 black or black and a blue. the blue is the heater usually. if its 2 black than you just need to check it with an OHM. meter. from 1 black -each white. and same with the other black.-both white if you dont get any reading than u need a new 02 sensor. if it reads check all engine fuse panel fuses with the key in engine run and engine not running. Fuses are all the little ones, some time they are labled 02 heater. please use a test light, do not pull these fuses! you will set every code and defeat the test process. good luck from Joe.

I ASSUME you mean the rear oxygen sensor???? 1 red wire is the o2 signal, the other is the o2 heater ground. the Orange is heater power The red wire in cavity 3 is the heater ground (terminal 20 at ECM). . the #1 cavity is BLACK, #2 RED, #3 RED #4 ORANGE looking at the connector its hard to tell you over print, but #1 is upper right, 2 upper left, 3 lower right, 4 lower left.

I need to know which wire on the 4 wire oxygen sensor (2 white, one grey one black) is the heat wire on a ford f-150 o2 sensor?


Hello! There are four O2's...Each O2 heater, left and right bank, front and rear, has it's own wire colors...These colors are "at the connector"...First series are the control ground sent by the PCM..
RR=White/Black...RF=Red/White...LR=Tan/Yellow...And LF=Yellow/Light Blue...........This series are the battery leads, hot when fuel pump relay pulls...RR=Violet/White...
RF=Red/Yellow...LR=Violet/White...LF=Red/Yellow...
