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
If just the knock sensor need to be replaced. I would say no more than $150.00
where is the knock located on 2001 nissan altima 2.4
40.00
where is it located
Motor
it is right below on the intake, on the blocks backside.
under the intake manifold close to the oil filter
how many gaskets and which ones are needed when you replace the knock sensor on a Nissan frontier w/a 3.3l v6 engine?
under the intake manifold, above the oil filter. A prestone hose passes just in front of it, realy tough to replace.
The knock sensor advances the timing to optimize fuel efficiency. When it goes out, your gas mileage goes down.
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.
If you have a local AUTOZONE IN YOUR AREA, you can ask them and they should be able to help you, I think I might need one on my 2001 altima also, so if I find out for sure I will answer back with directions---Good luck!
