Nissan Otti 2013 H92W O2 Sensor

[pwuser148132687723]

Salaam to all,

i am new here at pakwheels.

currently i need O2 sensor or the lambda sensor for my Nissan Otti H92W 2013 engine type 3G83.
its lower one with 4 wires (1 black, 1 gray, 2 white) with "OZA639-M3" written on it. its NTK.

i tried hard to find the same in Magazine line, Shershah and some electricians but unable to find the exact same.
i have tried to replace it with 3 or 4 other sensors with same looks and connectors but engine check light is still on.

the electrician says the reading is low on scanner means the sensor is faulty.
please guide me where i can get the exact same replacement or tell me some good guy with knowledge who can resolve my issue.

thanks in advance

OK, I got the replacement oxygen sensor in Pindi, but unfortunately, after replacing it, the check engine light still glows and the scanner still says a faulty oxygen sensor.
the electrician says it must be faulty ECU. but as you all know, ECU is "EXPENSIVE" and i cannot replace it on a theory.
please someone here knowledgeable suggest me what to do now ?
your help will save me bucks as i have already spent so much for scanning and TCS from Pindi to Karachi and then back to Pindi.
@askai37 i am unable to find it on internet either except some japanese auction sites which do not allow me to participate. I am already in touch with nissan singapore and the guy there quoted me $1016 for that oxygen sensor! (i found it in Pindi for Rs.5000
i know that Rs.5000 for O2 sensor is too much but its like "Majboori ka faida uthana")

Was connectivity checked? Check connectivity of o2 wire from ECU to o2 sensor. Its possible somehow the wire is broken somewhere in between.

and o2 sensors are not cheap. I recently ordered one for civic from Japan, and its cost is around $220.

I tried finding the o2 sensor at below website, but cant find it. Maybe you can check thoroughly.

first clear code from ecu. if ecu is at fault u cannot drive car easily. some times after removing part check engine light still lit because code goes in memory try to clear it first using scanner
and if u r in karachi contact me i have scanner with me and good knowledge of electronic as i am teacher in university so maybe i can solve ur problem

[Maverickiz3d]

^yes, if the ecu wasnt reset, then certainly the error code will remain there. But i assume the ecu was already reset by the electrician who's working on it.

To reset ecu, disconnect ground wire from battery for at least 30 seconds. 2-3 mins would be better.

[askai37]

codes that generates more then two times goes in memory will not cleared by disconnecting battery u need scanner for erase them. they even donot illuminate cel .

Salaam ..... thank you all guys for your responses.

by the thanks of Almighty, i found the correct O2 sensor for the said car from Asif. the guy who is so much active in business at Jamshed Road. i love the people who understands their work.
i thought i should write here my experience, it may help some other people.
there were actually 2 problems :
1) all other electricians were trying the old model sensors and mine is 2013 so we put in the O2 sensor of ek custom 2013 which worked fine.
2) the four wires. because the male connector (which is coming from ECU) was broken, it was hard to find just the right connections. finally i found Gullu Ustad at Jamshed Road, he connected all the wires correctly and boom. the light is gone. we were testing it for the last 6 hours or so and there is no problem at all.

Asif charged Rs 6000 for the O2 sensor and Gullu Ustad charged Rs.1000 for all the scanning and wiring etc.
anyway, i am happy that one of my problem is solved but still the car is giving not morethan 10km/L without AC. I still need your advise what to do to make it atleast 14 or 15km/L ?

Wsalam. For getting the fuel economy sorted out, get in touch with Ishaque (0337 7177753) and m sure you'll be more then satisfied with the complete diagnosis.
You would need to visit chah sultan for this checkup.

[shahidmianoor]

Dear Bilalahm,
Thanks for the response, i called Mr Ishaque but unfortunately he is in Pindi and i m in Karachi,
On call, the guy seems very polite and professional.

(Here is the reason ,, when he opened plugs they were black althoug those were iradium plugs wich i changed 3 months back) .. it was the catch that why it went black.. but that idiots and greedy persons that ur plugs were fake and changed it. those greedy dogs costed me almost 20,000 for all this but all went in vain.. i went t o him after 1 months.. he said change fuel from sheell to hascol.. another stupid things because he knows L of cars.. again i went to him 2 weeks back.. now car was giving 9-10 /L .. and again my plugs went black.. his ustad said i dnt know reason and come to him after ramazan.. this time i gave him 1000 just for oil change and checking of plugs...

If your spark plugs go black, it means your car is running on a ritch mixture
