I wrecked my car and the body shop replaced the bank 2 side 1 sensor. This has happened twice so far and now the light came one again yesterday. They are using nisssan parts. Any ideas what to look for? They replaced the manifold and y pipe alos. Could a leak cause the sensor to go bad?

You burning 91 octane???

Think about your combustion. If it is inefficient, then that could result is mucking up your sensor. It could be related to mods, poor fuel, or mucked up ECU.

I put the car to stock all around, use 93 octane from sams club. The ecu was my last thought because the interior did get a little wet when I wrecked it. How do you test the ecu?

My geuss would first be a harness issue.

Any way you get me the EXACT code #.

"The ecm controls on/off duty control of the a/f sensor 1 heater corresponding to the engine operating condition to keep the a/f sensor 1 element at the specified range"



There is 6 wires that things can be checked on. Did this go through insurance? If so I'd say it's time to go away from the body shop and to the dealer at the cost of the insurance company.

Terrentius

There is some merit to what KRRZ350 said above. Check into that stuff.

On the fuel point, may also be time to start using a different company for fuel. I personally use Shell V-Power. I have had no problems from it whatsoever. I have, however, had a lot of trouble with using Petro-Canada fuel - hard cold starts. I was informed that this may be caused by the fact that Petro-Canada puts a higher quanity of alcohol in thier fuel year around. They use it to inhibt your fuel lines from freezing up up in the winter. Unforturmnaly, that extra amount of alcohol can cause damage to your car. Not a cool thang at all.

I suggest finding a new fuel company....the list from Top Tier Gas should give you an insight on what company to try to use: http://www.toptiergas.com/retailers.html

Good luck :>)

Code that was pulled was a p2A03.

Bro, this code does not exist or at least in the service manual.
Also looks like the A doesn't belong to the code.

Terrentius

Well, I have looked a bit on the Net and it seems the code has to deal with the O2 sensor....you already know that. Now that you know that already, you now will have to try and figure to what is wrecking your sensors. You can replace this part all day but until you find the cause for these sensors shutting down on you, you will be no father ahead.

Hi i got the same problem with the air/fuel ratio oxygen sensor located on the canister near the front by the radiator........and i am pulling a code of p1283 b2......and i have done the tsb about the bolts and i would like to know if that means i should change the sensor going into the canister. thanks ANY help will be appreciated.

they printed the code out. I also did a search for nissan not maxima and pulled some stuff up. Nothing that helped me though.

Have you considered putting an 02 sim in its place?

Sorry. I didn't want to confuse you.
And yeah, looks like you're right
Definition of Diagnostic Trouble Code P2A03
This Definition of P2A03 is Applied to All Manufacturers Powertrain: O2 Sensor Circuit Range/Performance Bank 2 Sensor 1
, but i'm still wondering why this code is not in the manual. I thought all OBD codes are the same for all cars.

For example my SES light is on, because i have a trouble with O2 sensor too(P1031 A/F Sensor Heater), but i can simply search for it in the manual or in the TSB's and i immediately know what exactly is the problem.

Its one of the front main o2 sensors and thought that was a no no. I want this car to be perferct as its a lease car I return in 6 months. Thats why I returned it to stock. Could it be something with the front manifold that they replaced. Air leak causeing it to whack out. They also had to replace the y piped. Its their problem but Im trying to help out with a direction for them to look. Illl be there at 8 am tomorrow and this time I want a rental as Ive had it back numerous times and have been more than patient because I have 2 cars. JuST sick of putting miles on 1 car.

bodyshop gave up and send it to the dealership

trini_maxima

well since it says "NEWBIE" i am not yet able to start my own thread.....and i have searched several time but when i do i only get the tsb and i have done that. I did not mean to jack the thread, and it is related in that it is an 02 sensor issue i am having.

po8pimp

allright so I know this is a nissan not a ford and they both are completely different entities but, my expedition was throwing codes for o2 sensors like crazy. I replaced all 4 before I found that the PCV valve was the cause of the reading. The cost of 4 o2 sensors to be replaced ran me about 600 dollars and the PCV ran 4 dollars and fixed the problem. Not a single code for about 10 months now. trust me check the pcv valve. Keep us posted.

Terrentius

Yes, changing your PCV valve should be routine maintenance I do mine every two years.

Terrentius

Here is the location of the PCV Valve:

Possible causes list is kinda weaksauce, my vote still goes for wiring, in for teh dealer's fix and hope it get's taken care of for ya' man.

Air fuel ratio (A/F) sensor 1

Air fuel ratio (A/F) sensor 1 heater

Fuel pressure

Fuel injector

Intake air leaks

The car is less than 2 years old. I looked at the o2 sensor wiring and visuallt looks unscathed and routed correctly. He is trying to blame it tht I have the extra 2 degree timing bump but have never had a problem being stock or not stock. Its already going to the dealer because at this point I feel they are more qualfied.

redls1

iTrader: (2)

Bodyshop is now trying to blame it on I used to have a fujita and I have the 2 degree timing bump. They were suposed to take it to the dealership for them to look at and just had the code read. I had the code from autozone read and gave it to them before hands. Whats next?

po8pimp

ok so for all of these listed above I recommend:
SeaFoam intake cleaner.
Lucas Fuel system cleaner/ Tuneup in a bottle
I doubt it's a fuel injector.
Take some carb cleaner and start the car. spray a mist in the engine bay around the intake and watch closely. the mist will get sucked into the intake if there is a leak. don't spray directly into the intake filter just around to find a leak.

redls1

iTrader: (2)

I already recommended to spray brake clean and they didnt. I ill recomend the rest but its suposedly going to the dealer.

iTrader: (2)

They got it back frm the dealership and it was misssing a bolt in the manifold. Supposdly all solved.

Go sort out that guy at the body shop!
