i just took my car to the nissan dealer ship because of my service engine light was on and they told me my car was running real rich and that i need to replace all 4 of my o2 sensors can anyone tell where these sensors are and is this something i can probaly do myself. There trying to charge me $805.00 to get this done that seem hella high to me. Also does anyone know where i ca get a good price on these sensors any help would be greatly appreciated

thanks .org members

All four?? That's totally bogus. O2 sensors go bad now and then, but the statistical possibility of all four dying at once are somewhere in the realm of getting struck by lightning while giving Bigfoot a piggyback ride.

Get your car back from the dealer and tell them you'll need a week to scrounge up some funds (hopefully they won't try to charge you diagnostic if they think you're coming back). Go get your code pulled from a local auto parts store (many do this for free) and then post back.

Oh, and changing O2 sensors is pretty simple. I recommend you do it yourself and save a buck.

 

Typical dealership nonsense. They are theives. Get your car back and do it yourself.

 

thanks alot i thought that was a bunch of bull im picking up my car today and ill post back the result and again thanks for the help

 

another question do you guys know where all the o2 sensors are located i know there is i think 2 on my exhaust i know im minus one because of the ypipe where would the others be located

 

Ah! So did the Service Engine light come on right after you upgraded your y-pipe?

 

hahahahaha. nice analogy typical stealership

 

no i have had my y pipe for about 2 years and this is the first time my light has ever came on

 

First of all- all 4 sensors are likely not bad. If you insist on changing them...
bank 1 sensor1 (firewall side 1st from the top...closest to engine)
It has a black long wire covering
Bank 1(named after #1 cylinder) sensor 2 is white, in the cat

front or bank 2 sensor 1 is right out of engine passengers side- remover exhaust heat shield. It is blue
the last one, bank 2 (radiator side) is red(toward drivers side and underneath) Use a 7/8 wrench to remove all. Hint: You can cut the wires and use a deep 7/8 socket when removing old ones.

If you have been running rich, youll want to replace the spark plugs and also wire tie the wire harness into the ecu (drivers and passangers center panel) When you hit bumps it can come loose and trigger SES Lights. If you live in NJ, look me up, Ill do it for you...
If all else fails, get a reflash of the ECU from the dealer- actually, do this first. $80. Do you smell eggs? bad cats? Hopefully you do cause then they have to fix all for free 8/80 federal emmisions.

got my car back from the dealer and it says on the paperwork scanned codes p0172/ p0505 rich fuel condition. failure in o2 sensor bank 1/ sensor 2.

then it says recommend replace all four o2 sensors

 

i was told by a o2 sensor specialist and he told me that all four of the sensors for our cars are exactly the same the only difference is the lenght of wire and the connecting plugs is this true. If this is the case why not just by the cheapiest of the sensors and just splice them. IS THIS POSSIBLE

 

need to khow if this will work info please

 

So the code says one O2 sensor is bad and they recommend replacing all four? That doesn't add up to me. I'd just replace the sensor that is mentioned in the code pull on your own. I'm betting you wont see the SES light again after that.
