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.

I have a 1993 mercury villager my o2 sensor has 2 blues a white and a black and the wiring on the van has a black red and white and i need to know what way to wire them


Sounds like the wrong sensor for the car. The correct sensor would also have 3 wires: a signal wire, a ground, and a voltage, reference voltage wire. The 4 wire sensor sounds like it might be a Heated Oxygen Sensor, not applicable on your car.

My trooper is giving like 6 miles to the gallon its a V6 2.8 engine. I dont know where th oxygen scensor connect.


Hello! I have the wiring to your engine and perhaps a solution...The wire color from the ECM on Connector D pin #7 is White/Green and goes to the O2 sensor...The color at the O2 sensor is Black...White/Blue is connector D pin #1...wire colors that have aged are easily mistaken White looks Yellow with age...connect the O2 sensor to D-7...The O2 sensor is White/Green NOT White/Blue (which looks like Yellow/Blue) this wire is the Check Engine Connector...Tell me how many wires are either cut or misplaced? If we eliminate wiring we can concentrate on why your getting 6 miles /Gal...

If the vehicle backfires or runs poorly My next suggestions are to check the plug wires to be sure they are in the correct place...and #2 to check the timing...the left bank=1, 3, 5 and the right bank=2, 4, 6...Firing order is1, 2, 3, 4, 5, 6...CCW on the distributor...Stick with me and we'll have it purring. see timing below...

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...

If you have any questions feel free to ask...Guru...Saailer

Sounds like the rear O2 sensor is at fault, you may try to replace it yourself, if you are mechanically inclined.

2004 gto ls1 motor is running rich and dtc code is P0131


that would be your best bet it is very hard to diagnose a injected v8 with out the right equipment but speaking from experience ( due to the fact we in Australia built these cars) the oxy sensors cause all sorts of problems and swapping them over does't necercarly prove much

O2 sensor on a 1994 toyota tercel


Usually the O2 sensor will be on the exhaust manifold close to the engine, I'm going to assume you have a pretty good idea of what you are doing so if you need more details don't hesitate to ask.
