Replacing 2004 Hyundia Elantra O2 Sensor

The 2010 Dodge Caliber O2 sensor wiring has four wires: two white, one gray, and one black. The wires are typically color-coded, so you should be able to match them up with the wires on the replacement O2 sensor.
Here is how the wires are typically connected:

• White wire: Sensor signal wire
• White wire with black stripe: Sensor signal ground wire
• Gray wire: Heater power supply
• Black wire: Heater ground

You can use a multimeter to confirm the correct wires if you're unsure.

Personally I would join the two blacks to the two whites, the white to the black and the blue to the grey, most it can do is blow a fuse or not work so worth a try, looks like the blue is possibly 5v ref voltage from ecu white earth and blacks are data back to ecu?

Which engine ?

you need the factory color code and the bosch color codes.
then wire per that. there is no other way. (universal)
that is the penalty for not using a PNP sensors, plug and play.
do not mess up,wiring the 1 heater to the CELL + wire
risks blowing out the senor or ECU. a $500 error.

here a list. 89-98 list.
first the bosch list ,with comments. my 91 , just and example.

all bosch unversals sensors have a paper inside,
and is very hard to read and understand.
my guess is it fails german translations.....
no biggy
your car is a 4 wire sensor.
on my cars 96 , the heater wires are non polar so are much easier. lets do them first.
the bosch color is.white, on my car its blk.
so i wired, bosch white to my cars black. x2
bosch gray is sensor ground, (special) wired to cars white wire.
every year, suzuki changes wire colors, not reading the FSM is FAIL.
and last my Bosch CELL+ pin is black and wires to my cars blue.
O2 are like battery CELLS, and are Polar.
Suzuki changed the blue color like a drunk sailor spends money.
a royal PITA. that is. LOL !

the for sure solution is to look it up in the FSM.
for all wire, find your blue, and win !

see the 9 times suzuki changes here, prior to 2004

http://www.fixkick.com/sensors/OxyGen_sensor_help.html

did they change in 2006, ? Ill never know, as Suzuki is bust here.
nor will i pop for $15 to find out. When my Suz, dies, that be the end.
btw 2: the sensor colors on any suzuki are "NCA". FSM drawings.
no color assigned.
the colors mentioned are HARNESS colors in the sensor side.
suzuki uses many different brands sensors and colors, or reserves the right to do so at anytime. Bosch, NGK, Delphi, etc.
tricky huh? thus the pages , linked.
back in 1996 they should have set ISO standards but did not....

i hope that is not confusing.
but in a nut shell.
1: grab bosch sheet,
2: grab the car schematic, for ECU. (fsm, or alldata, or mitchells)
there is your answer.
no man as the blue wire color on all car or all suzuki;'s
not yet. tell my yours and ill update my records.

The two white are the heater
The black the ground
The gray the O2 Sensor output,
you back probe to check Voltage
& Switching Times

The vehicle wiring harness does not have to match
the sensor, BUT -- you need to have the same
connector on the sensor

If you have a universal cut & splice, you have junk,
and we given the wrong part

Get a Bosch or NGK, OEM sensor & just
plug it in

The wires going into the MAF are as follows:

White/Red = Ignition voltage

Blue/Black = E2

Black/White = E2G

Yellow/Green = THA (This is the IAT signal to the PCM)

Gray = VG

1) ECM Fan Clutch 1) K160 18BR/OR Park Lockout Solenoid Control Green
1) BR / OR = Brown/Orange unit with Green
2) K900 18DB/DG Sensor Ground 2) Black
2) DB / DG = Dark Blue/Grak Green unit with Black
3) K161 18BR/LB Fan Speed Sensor White
3) BR / LB = Brown/Light Blue unit with White
4) Not Used
4) Not Used
5) F856 18YL/PK 5 Volt Supply Orange
5) YL/PK = Yellow/Pink unit with Orange
6) F504 20GY/PK Fused Ig. Sw. Output Red
6) GY/PK = Gray/Pink unit with Red
With this, you have 5 due color cables unit to the 5 full color cables. Run.

Good luck, and rated this help (and us chat).

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.

black is usually power and if there is a blue its the feedback to the pcm
