The sensor you need to replace is called Speed/Revolution sensor. The part number is 31935-8E006. Now, don’t waste your time by buying aftermarket sensor. I heard that it may cause issues. Go with factory sensor. The price of the sensor retails at $125, but do some research online and you should be able to find one for $100 or may be even less. You can also negotiate with your local Nissan dealer.
In this section, I’ll guide you on how to replace the sensor. That was one of the easiest sensors I have replaced so far.
First thing you need to do is to turn your ignition off and remove your keys from the ignition. Then loosen the driver’s side front wheel bolts. Jack up your car and remove all 5 bolts.

Remove the wheel. When the wheel is removed, you’ll see splash guard in front of you.

Take a Philips screwdriver and remove the bolt (pictured). Once the bolt is removed, slide the splashguard so that your brake disc is holding the splashguard.

From there, you should see the sensor. The sensor is attached to your transmission.

First, take 10mm ratchet (I’d say with ratchet it would be easiest, but use one with small head), and remove the only bolt there is.

Once the bolt is removed, push the sensor up and then to you. Then, just remove the harness.

Next thing to do is put the new sensor in the transmission and push it down. Once it’s down and aligned, screw the 10mm bolt in. When the sensor is in the place, connect the harness.

That’s it, now just slide splashguard in the right place and secure it with a screw. After that put your wheel back on, remove the car jack and drive around to make sure sensor is not faulty.
If you still have check engine light, just reset it and you should be good to go. If you have any questions, feel free to post it here.
