I bought it for the knock sensor relocation on a 2001 Xterra. The upstream is in the engine compartment, in the exhaust pipe. Wear mechanics gloves if you attempt this since you will definitely cut your hand on the sharp edges of the engine block. Especially since that picture has Twin Turbo on it. It is a pain to get at, only one screw takes a couple hours to reach it. Trent I have the same issue with my 2003 frontier 4x4, 3.
I ran into the same thing this week. When it comes to your Nissan Altima, you want parts and products from only trusted brands. I once read a post about the relocation but can't find it again. I don't want to get into the middle of the job and then realize that some of the parts are in different places or that we just dont have it at all. I know that we share similar engines with the Z but will that write work for our car, like word for word and part for part. Post some pics and tips if you can.
What we did change was the crankshaft position sensor that was bad. Intermotor® is a complete engine management import line that includes ignition and electrical relays, switches and sensors with a concentration on high technology categories such as computerized engine controls, fuel injection, and emission controls with coverage for every part number with an import nameplate. I think replacing it is not worth the effort. To get at it from the bottom. It should run for a few seconds then shut off. Replacing this same knock sensor part on the 3 L and 3.
Since I was under the intake anyway dealing with the aftermath of my overheating issue, I replaced this in hopes that said timing advance could be due to the sensor not reading knock. I hear they can quit working easily so getting to it easily would be a plus. I'll be checking codes as I go home. A misfire, pre-detonation are some of the causes that trigger the code. How can I reach the knock sensor? One of the things that shock me is the far-reaching number of automobiles affected by this Nissan knock sensor code. The problem is the location.
I hear they can quit working easily so getting to it easily would be a plus. First, locate the oil filter from under the car. However, he rset and suggested that I run my car a few more days and see what is happening. Remove the bolt and there's enough wire to pull out and remove the wiring from the sensor. Its possible though the sensor has failed.
It can be accessed from under the vehicle. Question is, where is that located on her 2. Just warning you that it's not always the Knock Sensor despite the trouble code!!! It is located under the manifold on the backside or firewall side of the engine. When you do this, you cut the original harness and splice in a replacement pigtail that attaches to the new location. Easy fix once you find it. Hear from other customers via the 216 reviews on parts for your Nissan Altima.
We couldn't find anything that could tell us where the knock sensor was located!! So that's why I made this video. For this reason I don't even bother testing them anymore, because I've never seen anything else go wrong in the circuit. The knock sensor will resemble a small battery terminal with a bolt through to the engi … ne. . But, I got the computer to clear the codes, so mine at least starts.
But I do not know if the store will accept it or not. What you do is relocate the knock sensor to one of the plenum bolts. Knock sensor indicates a knock coming from the engine, perhaps from cylinder 4. Do not forget to buy intake gaskets as the old ones might not seal well. The sensor is attached to the cylinder block, cylinder head or intake manifold. I'll post here what I find. About 20 seconds later, the dash board lights come on.
It's located below the intake manifold up above the oil filter as high as you can reach. Then look for the knock sensor attached to the engine block higher than the oil filter. I don't want to have to pay a whole pay check to get this job done. Then remove the intake manifold and it's right in the middle of the pistons. Posted on Feb 08, 2010 Melvia, Knock sensor located under the intake manifold between cylinder 2-3 I believe, hard to change with out removing intake manifold, but can be done.
