you should have three oxygen sensors on your car, one for each bank of three cylinders; should be towards the Y pipe on each exhaust manifold. Additionally you should have one on the exhaust pipe before the cadilitic converter.

glad you posted what colors you do have , cause 2 resources didn't match ,actually 3 , i did find a match to your colors was a 97 year model premium radio, so we have a match .....

black/ light green = ground
dark green = left front spkr +
purple = right front spkr +
blue/white = right rear spkr -
brown/blue = left rear spkr -
brown/yellow = left rear spkr +
blue/orange = right rear spkr +
black/yellow = park lamps
brown/red = left front spkr -
orange = dimmer signal
pink = fused battery +
green/red = radio choke relay
red/white = fused ignition
blue/red = right front spkr -

Have you checked fuel pressure? How about spark on all 6 cylinders? Maybe a coil?

A new 02 sensor will come with new wires and connector. If not get back with me I think there is a repair kit for that problem.

posted 3 times now and forget to say FRONT SENSOR>
right, not the Rear 02 sensor....?
and still no engine stated.!
nor country, (USA calif, usa FED, or canada)
strike three you are out.
there are 3 engines,
based on all 3 engine schematics, my wild guess
is 7AFE engine. (the brown wire clue) 1,8L
4AFE (1.6L)
or 1ZZFE engine, DOHC 1.8L

Po141 code on my 2003 Chevy s 10 and I changed my down stream sensor and reset the code about 500 miles later it came back on I reset it again and 200 miles later it is back on again what do I do now

unplug the O2 sensor. Turn the key to the run position. Check for 12 volts at the pink wire.

If there is no power check the fuse (O2 HTR). If the fuse is good you will need to find the open in the pink wire.

If there is power hook your test light to the power side of the batter (Positive lead of voltmeter to positive side of the battery. check the brown wire with the engine running. You should see 12 volts or the test light should illuminate. (the computer supplies the ground for the heater circuit).

If there is no power or illumination check the brown wire for continuity between the sensor and the computer. If there is power than either the new sensor is bad, the wrong sensor was replaced, or there is corrosion in the power side of the wiring which is a little more difficult to figure out.

The brown wire from the downstream sensors is broken or otherwise not connected to the computer. Check for damage to the wire.

2008 Jetta upstream O2 sensor

Right do you mean the wires to the O2 sensor from the loom or the wires from the plug to the sensor ,So i will explain what i know here and thats all i can do for you.On our europeon motors their is a 4 and 3 wire O2 sensor type,now on the sensor side of the plug their will be two wires the same colour normally white or gray ,these two wires are the heater circuit so should show a resistance with a meter ,now the coresponding two wires in the loom plug should read 12v with the plug disconnected ignition on .Now the other two wires are for the readings so push a pin through each cable and then with engine running plug connected you should read 0-point something which varies with engine speed somewhere between point 7 to point 2 varying with speed .if it stays around the point 4 mark then replace as its not working correctly ,you should be able to read the voltages with a code reader though

1990 Chevy GMC Suburban alternator wiring

Well, according to my diagrams for 88-94 models, the alternator only uses the red and brown. There are pink-black wires that power some of the sensors and solenoids but should go to a fuse marked ECM in the fuse box.
Have you tried hooking up the harness without using the pink-black wire ?

Four wires (black, brown, purple & striped) going into O2 sensor and three (two black one white) coming do they connect?

Year make and model ?
The sensor probably has a heater, so one black is for the heater and the other may go to the computer.

Ford p1151

This code is related to the oxygen sensor on the drivers side of the vehicle. Most times the sensor just needs to be replaced. If you want to make sure, it is the sensor and not a wiring problem or another condition causing this you would need to preform the following test.

Monitor the bank 2 oxygen sensor (O2) voltage on the scanner. If it's showing lean (under 0.5 V), force the engine rich using some propane or carburetor spray. The O2 should go to 0.8-0.9 V.

If the O2 does not go rich as it should, check the voltage at the O2 sensor on the Black (BK) wire. Perform the same test adding external fuel. If the O2 shows rich when using a voltmeter, re-check at pin 44 Red/Black (RD/BK) wire at the Powertrain Control Module (PCM).

If the voltage at the PCM is low as the scanner shows, but the voltage at the sensor responds and goes rich, locate and repair the open circuit in between the PCM and O2 sensor connector.

If the voltage is stuck lean at the O2 and PCM using a voltmeter, cut the BK wire at the O2 sensor leaving all other wires connected. Re-check the voltage on the BK wire. If it now goes rich when adding fuel, check the RD/BK wire for any continuity to ground and repair the wire as needed.

If the wires test out OK and the O2 sensor does not switch as it should, replace the O2 sensor and retest.

Hope this helps.

I have sensor heating circuit malfunctiom on my 1997 astro van the code is po135 how can i find out how to fix this problem

The heater circuit feeds the other 2 sensors and since there is no code for them we can reasonable assume that the wiring an fuse is good up to the splice.

Bank 1 sensor 1 is the sensor before the cat on the same side of the engine as the number 1 cylinder. If you check the vehicle side of the connector you should see a black, pink, purple and tan wire. Pink is the power to the heater, Black is the heater ground. Make sure there is 12 volts on the pink wire with the key on (possibly running) and make sure the ground is good.

If those 2 are good than I would have no problem changing the O2 sensor.
