Great start! :tiphat:

The new part number is backorded? Did you get the car back while waiting? Since it sounds like I have the same issue and need a car.
Somethng funny the service rep said when I told him the car had K&N filters. " I wonder if the oiled filter could have damaged the O2 sensor.":shakes head::rolleyes:
I said , "Uh maybe got oil on the MAF but I didn't see any with visual inspection and certianly didn't effect the O2 sensor..."

Looks like this service dept might be trouble...

Good bye easy trip to the dealer for warranty work next time you'll shut your mouth and get it done for free.

I asked the same guy if a CBE would be ok on the day I bought it and he said it should be fine? :confused:

On the day you buy it they will tell you whatever you want but you didn't get it in paper did you now?

I've got the car back and was told it was okay to drive until the part comes in although since it is my second car and not my DD, I have not put many miles on it with the service engine soon light on. Also haven't beat on it in case the cat temps are out of whack.

You really need to simply hand over the keys next time and not say anything about your mods if you don't take the car back to stock before going to the dealer for service.

Yea, I will keep everything on the down low from now on. I got the car back with the same story you had. Part is on order p/n 22693-3RC0A. Wonder how long this will take? I also worry about fouling the plugs on that bank if it is enough to effect the mpg.

Eh, I wouldn't worry too much about the plugs. Remember, the wrong O2 sensor is just reading slightly out of range on one side compared to the other. If anything the engine may try to adjust for the apparently rich condition by running a little leaner than usual. But overall I don't think you'll hurt anything else by driving it, just keep it below half throttle and below 3500 rpms to try not to put too high of a load on the engine while the fault is active. My concern right now with my car is more related to catalytic converter temps, not the plugs.

Judging from my past experience with the Nissan dealer, it will probably be at least a week, maybe two before the part will be in. Drive it easy till then.

I presume a rich condition is way better than a lean condition. Wouldn't that also be easier on the CAT? I had a stretch where the MPG just started dropping like a rock. I used my scanner to reset the code and it seemed to stabilize. I have a truck to drive too but I am getting tired of its 14mpg.
Thanks for the input have a great one!

Backordered Sensor Came In
 

Dealership called me yesterday; O2 sensor is in. Getting it installed on Monday. Will update with results next week.

look for exhaust leaks. my dealer replaced o2 sensors to no avail and it was just leaky HFC gasket. Z1 sells a all metal one that seems pretty good for about 45 bucks.

Good call. Will do.

Lots of knowledge in here. Good forum.

My part is in also in and goes on tonight. I wonder if they will give me the old part?

Depends. I can just about guarantee that they won't say yes if you don't ask. ;)

Let us know if it fixes the problem! Glad to hear your car will be fixed soon!
