Works!
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.

Just what I needed ...
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
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!

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

Just what I needed.
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.

Dead on arrival!
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.

They worked for 10 Months....
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)
