The knock sensor (if underneath the vechicle)is located above the oil filter just to the left, behind your antifreze return. It is a pain to get at, only one screw takes a couple hours to reach it. I filed (narow) down and old wrench because i didnt have enough room, once loosen i did it by hand. you can see it from the top of the motor between the 2nd and third fuel injectors (you can only see the screw you CAN NOT see the knock sensor). Have fun! ALSO IT YOUR CAR IS OCCASIONALLY STALLING RUNNING RICH AND SOME BLACK SMOKE WITH YOUR RPMS JUMPING AROUND. IT MAY BE YOUR TEMPETURE SENSOR EVEN THOUGH THE COMPUTER READING SAYS KNOCK. ITS $21 COMPARED TO $180 AND IT WAS THE CASE FOR ME. COUPLE MINUTES COMPARED TO SEVERAL HOURS. THANKS

Knock sensorThe knock sensor for a 1996 Nissan Altima is located on the backside of the block above the oil filter.But before you go and change it out, run a tank of the best/hightest rated gas you can find and see if that fixes the problem. On my 1995 the Knock sensor is located under the plenum and intake manifold on top of the middle of the block.

how many gaskets and which ones are needed when you replace the knock sensor on a Nissan frontier w/a 3.3l v6 engine?

The knock sensor advances the timing to optimize fuel efficiency. When it goes out, your gas mileage goes down.

Disconnect the wire from the sensor, use an open ended adjustable wrench to unscrew it. take a new sensor and screw it in. on a different model (if not a standard sensor) there is a nut and bolt holding it in, use the steps above to replace it

under the intake manifold, above the oil filter. A prestone hose passes just in front of it, realy tough to replace.

The knock sensor for most Nissan V6 engines is located directly under the intake manifold. So to replace it, you have to remove the intake manifold. Good Luck.

The knock sensor on Nissan 300ZX non-turbo from 1990 thru 1996 is located below the lower intake manifold on the rear of the engine block. To replace the knock sensor the upper and lower intake manifolds need to be removed. It is always best to replace the knock sensor with a new one considering its major dissasembly.

The knock sensor is located under the intake manifold on the passenger side of the engine. It can be accessed from under the vehicle. Look above and to the slight left of the oil filter on the back of the engine. The knock sensor will resemble a small battery terminal with a bolt through to the engine.
