97 Maxima
I got the 77 from the ECU.
Since I need pass the emission to get the new stick, I reseted the ECU before I went to inspection.
But the test showed that several sensors are "not ready".
They suggest me to drive the car for a while and come back in 15day to get a retest.

Does anyone know how to sucessfully pass the retest without fix the rear O2 sensor?
How many mile do I need to drive? Currently I drive on the local below 40MPH since I was told that engine light is easily on when driving and quiting from high speed?

Really need you Help!

thanks

 

Fix it. You will pass.

 

The dealer ask more than $200 to fix it.
I want to DIY, but I do not know how to do it, evn where is the rear O2 sensor?
Plus, the rear O2 sensors does not affect anything.

 

www.oxygensensors.com OEM $63.99. Crawl under the car, look at the cat. The sensor will be right there, can't miss it. Spray with WD-40, unscrew, replace. The sensor measures the oxygen after the cats to insure that everything is working properly. It will affect emissions.

 

I think I should raise the car a little bit to make sure I can crawl.
So my question is whether I need buy a jack stand or I can just use the jack along with the car?
Thanks

 

I take it you are kidding when saying that you wont use a jack stand...
