Genuine Nissan 23731-6N21A Crankshaft Position Sensor

Right now it’s been installed 2 weeks, and went 500 miles and no repeat light! Autozones, I installed twice with failures within 100 miles. This came in the Nissan OEM box, it appears to be a OEM the fact the car is now running great I would have to believe it is. Hopefully I haven’t spoke to soon. I did alot of research and aftermarket crank sensors will constantly fail in the 2006 Nissan Altima. If this helps, I believe this is a solid buy, and saving 80 bucks from getting it from the Nissan dealership.

Put these in and the car is not returning the SES light anymore and running as expected. If you get the P0335 error in your Nissan w/ the 2.5 4 cylinder, replace both the crank positioning and cam positioning sensor at the same time - it's the same part and replace them w/ genuine Nissan parts - they look different than what comes out due to a redesign. The aftermarket products are a tad to long and the crank with nick the crank positioning sensor.

Perfect replacement for my '06 Altima 2.5S. Check engine light was on so I went to AutoZone for a free computer scan, got the codes then found out this was the part I needed. No problems installing the part, it worked like a charm, now my check engine light is off and my car starts no problem!

Packed in Nissan box, couldn't swear it was OEM, the one I replaced had a plastic body..

Worked like a charm to get rid of the code and engine light. Although the one in the back was a beast to get in! But saving $200-$300 on labor was well worth it.

I installed it and got the same fault then installed another one from a local supplier and the fault cleared. Fork truck now fires up and runs great. Senser came DOA.

I removed two starts because they only lasted 10 months. I thought they were oem but I don't know anymore. I think I'll just bite the bullet this time and go to the dealer down the road.... It's always a risk online. I thought they were it.My old rating: 5 Starts: Great, sensors. OEM and worked great, fixed my car not starting! (Crank sensor)

Worked fine, happy with the purchase.
