How to Replace Camshaft Angle Position Sensor 2002-06 Nissan Altima L4 2-5L

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Cam angle sensor on this two five Altima is located here atop of the head. It's got the connector on it, and it's bolted into the head. To remove it, start by disconnecting the electrical connector. There's a lock underneath. Use two hands, one to push the lock in or up to come off it. Wiggle it off. Place that aside.

There's a 10mm bolt underneath that's holding it into the head. Just sneak a 10mm socket, ratchet and extension in here. Can't quite get the bolt out. This hose is in the way. Trying to loosen it some more with my fingers. There it is. The bolt is out. Put that aside so I don't lose it. I'm just going to have a paper towel close by in case some oil comes out when I free this from the head. Just try to push on this end here where the bolt goes in just to break the seal. It's got an O-ring. Just kind of wiggling it back and forth. Here it comes.

Here’s the old cam sensor from our vehicle and a new one from 1AAuto.com. It looks a little different, but it operates in the same way. Has a single mounting hole. These connectors appear to be upside down from one another, but you can turn the connector in the car and just plug it in, so I'll show you that when we install it. But this should work for you and get your car back on the road.

I'm going to take our new sensor, and we're going to take a little bit of oil from inside the hole that it came out of, the original one. I'll put some of that oil on the O-ring. It slides in. Move the connector out of the way. Slide this into place. It's probably going to be a lot tighter because the O-ring is fresh. Push it in. Turn it down so it lines up with the bolt hole.

Reinstall our bolt. I'm going to get it threaded in with my fingers. It is a steel bolt going into aluminum, I'm going to cross thread it. Get it on the bolt seeded all the way down. Now I can slide the 10 mm socket and ratchet in here. I'm just going to tighten it down. It's a very small bolt going into aluminum. I don't want to get it too tight and break it. I'm just going to get it tight.

It doesn't want to turn anymore, so I'm going to stop. Take our connector. Just like I said, it can be turned a little bit. So now the lock is going to be on the top. It is keyed. It can only go in one way. Cam sensor is replaced.
