Oxygen O2 Sensor Upstream 234-5060 for Nissan Altima Armada Frontier Maxima Murano Pathfinder Pathfinder Sentra Titan Xterra Infiniti M45 FX45 QX56 Q45

Seems to work great so far. Easy to install myself.

Item worked great got rid of the check engine light and all is good will buy again. Unfortunately the light did come back but the company has sent a replacement and it looks good so far. Will buy from them again.

Didn't fit, waste my money.

Easy to install

The price was good but this is the second sensor I have replaced. The first one quit working after 2-3 weeks so I was given a free replacement. Same item but may have just been a bad unit. The second failed after 2 weeks but I am left with not replacing it within the return time frame because it is winter and I have no place to replace it out of the weather. So I will have to wait 3 or months for better weather to complete the swapout. I can't drive the vehicle without a part installed, even if it is defective. I would like a refund but can't send the defective part in time. Your guidance and help is appreciated. What are my options?

It fit perfectly and was super easy to install. Literally took like 5 minutes. I highly recommend you get it.

Great condition

I replaced the original one for this O2 and the check engine light still on.. mechanics said this always happens with cheap O2. Same code appears.
