whats wrong with this forum?

hi, i have been waiting on a reply for my post for the last couple of days and no reply.I See your post and may be i can help.I have a 02 sentra with 1.8 liter engine and i am sure yours is the same.I have replaced crank sensor twice on this vehical.Jack the car up on the right side as high as safety permits only you can tell this.Put jack stands under the car for added safety.The crank sensor will be located under the starter to the left.You will have to put some effort in this to get your arm up in there and feel for the sensor....you will never see it...once you feel a connection that has wires to it and a 10mm bolt attached to the connection,then that's the crank sensor..like i said you will never see it until it's out..you can only use a 10mm wrench...once bolt is out .twist sensor and pull until it comes out..installation is in the reverse...GOOD LUCK

 

Thanks. I had to remove a couple of brackets to get to it, but finally did and thank god replacing it got the car running again (though now I'm showing a p1065 code).
I've driven 2 Sentra's past 300k miles with virtually no problems (one-a 98 with an actual distributor-is still running sweetly at 320k) and I was hoping this 2004 would continue my sentra streak of fortune. I'm hoping this added level of computerization complexity doesn't turn my Nissan dream into a nightmare.

 

glad you got her going.

 

Hi guys. I did this yesterday on a 2004 Nissan Sentra with the 1.8 liter QG18DE engine. Like many others I was having a lot of trouble with removing the crankshaft position sensor. I was accessing it from underneath, by feel alone because it can't be seen from any angle. I got it so that it rotated freely but could not be pulled out. Then I soaked it in wd40 as best I could, and began prying at it. I pryed at it with a large flathead screwdriver which I brought up there from the right hand side, placing the head behind the little flange that the bolt goes through, and using a part of the structure as leverage. I alternated between this and wiggling the sensor. The way I tried to wiggle it was more of an up-down and side-to-side motion. This may have helped the wd40 to get inside to that o-ring. After trying these 2 things over and over again, I eventually found that the sensor had a little bit of give left and right. From here it was just more of the same. So to those who decide, like I did, that they have to take a whole bunch of engine stuff apart to get to it, give it one more go, don't give up, and eventually the stupid thing will come out without removing anything else from the engine. Also, this may seem kind of dumb, but I was wondering the whole time if the sensor was going to have a few quarts of oil behind it, and to those wondering the same: No, it does not have oil behind it.
