Need o2 sensor harness wire color code - 1997 Hyundai Elantra

Hi,

Please use the catalog from the advanced autoparts website or Mcmaster-Carr catalog in order to identify the product and then have access to the particular wire that you're looking for. You might use both resources just to ensure that the color isn't picked at random depending on the source of the part creation.

Thank you.

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.
sorry.
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

posted now 3 times.
no engine stated (of the 3)
no symptoms stated. or job.
front or rear , oBD2 sensor not stated.
on your other post, i answred for all 3 engine
front 02 sensor B1S1.
all 3 engines, the ECU schematics on the 02 pins.

go back and read. your other posts.

get a new plug w wiring from the dealer

O2 sensors just plug in.

Locate the wires running off from the O2 sensor. There should be two. The black wire is the ground wire. The other wire, which may vary in color, supplies power to the sensor.

2 Connect the power lead to the corresponding connector on the chassis's wiring harness.

3 Connect the black, or ground, lead to the corresponding connector on the factory wiring harness.

3 wires, "how do i wire it" are simply explained. all universal 3 wire o2 sensors will have 2 wires one color, the other wire a different color. the 2 that are the same color are ground and power for the heater and it doens't matter which one is which. so ground to the motor, power from the gray wire on the fuel pump, or anywhere you want to pull 12 volts while the car is running. i have a dedicated fan relay that doesn't use the ecm and runs off the key, so thats where i went. the different color wire goes to the stock sensor wire, it's the signal.

Oxygen Sensor problems... P0135 (Bank 1, Sensor 1) and P0141 (Bank 1, Sensor 2)

P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it.

The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

Symptoms: You will likely notice poor fuel economy the illumination of the MIL.

Causes: A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

Possible Solutions:
Repair short or open or high resistance in wiring harness or harness connectors
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)



P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141.

Symptoms: You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Repair short or open or high resistance in wiring harness or harness connectors


Hope this helps (remember to rate this answer)..

There should be 2 ways of doing this. Get a portion of the wiring harness off a wreck or see if Ford can get you a new wire. Someone else may know more about this but some wires have heating elements in them and some may have resistance in the wiring. A plain wire would not be the same.

Please look at page two. It shows most connect cross reference to Bosch Universal 4 wires O2 kit.

On the front O2 Sensor, the signal wire s Purple. On the rear O2 Sensor, the signal wire is Purple and White. (You will probably have to look at the wire colors on the main harness side of the O2 Sensor connector, not on the sensor itself.)
