You may also have a timing issue, that a tune up might fix. The knock sensor on my truck has been bad since I last owned it in 2008. Not great, as if the mpg on these things was great to begin with, lol but better than a kick in the butt with an iron boot. Truck still misfired at 4k rpm, then slowly got worse. Although 10 different knock sensor codes can set from P0325 through P0334 the most common code you'll find is the P0328.
Be sure to have a set of jack-stands to keep you from getting crushed! Just warning you that it's not always the Knock Sensor despite the trouble code!!! It is located under the intake manifold, bolted to the middle of the engine block. When I finally tore the engine down and tested the sensor, It measured good according to the Haynes manual. Besides that, the knock sensor is really an important sensor for getting the maximum power and fuel economy out of your engine. Then look for the knock sensor attached to the engine block higher than the oil filter. It detects cylinder knock incorrect detonation of the air-fuel mix and the engine computer adjusts timing and air-fuel ratio to compensate. We consider this a difficult repair even for experienced technicians.
People just want them to pass state emissions inspection without dumping a lot of money into a car that won't last much longer. If there's a short circuit, often the extra pressure will… autozone. I would think that using a Maxima sensor would have been the better way to go. Then you put a new manifold gasket on and put the manifold back on making sure to tighten all bolts. They mount the knock sensor in the lifter valley of the block on these engines. Sounds like they are searching for more money from an unsuspecting female. Again, while standing next to the hood release, remove the tape from the back of that harness and you will find the two wires.
I bought a Nissan knock sensor about a year ago but never put it in. With the interior hatch panel removed, close the hatch. When the knock sensor detects a sudden spike in pressure in the cylinder walls, its sends a signal to the engine control module to adjust the ignition timing accordingly. It detects cylinder knock incorrect detonation of the air-fuel mix and the engine computer adjusts timing and air-fuel ratio to compensate. Tape off the open pigtail and secure to prevent rattling. This part is also sometimes called Nissan Pathfinder Engine Sensors.
The one the guage uses is mounted on top of the intake manifold. The knock sensor will resemble a small battery terminal with a bolt through to the engi … ne. Pathfinders need all the help they can get! If there's a short circuit, often the extra pressure will close the open circuit. The guage sensor will not cause any driveability problems, it's only used to send a signal to the instrument panel on the dash. The knock sensor on my truck has been bad since I last owned it in 2008. It's screwed into the engine block with a 12 metric bolt. There are lot of reasons why cutting is not the best option if you have another option to choose from.
I also learned the hard way that the connector for the Maxima wiring harness does not fit the sensor for the Frontier. The sensor itself has a separate part number that I don't remember, but can supply if someone is looking to do this mod and needs the part number. Learn how to perform the reset procedure and replace the ignition lock cylinder. It looks like the sensor is the same but you'll need the Nissan Maxima harness to connect it. The sensor itself has a separate part number that I don't remember, but can supply if someone is looking to do this mod and needs the part number.
And Bank one is passenger side side where cylinder one is located and O2 sensors 1 and 2 are same sequence as in bank 2. After reading the posts, I got brave and did the replacement this past weekend. This pressure is converted into a voltage signal and sent to the Engine Control Module. In this article will explain why it's worth your time to address the problem. I have a 1999 Pathfinder that needs the knock sensor replacement.
You can kinda see a blue plug in the other pole exit of the harness, if you're looking at the sensor from the top it is coming from the left side of the plug. Standing at the rear driver's side of the hatch, fish your left hand through to the back of the hatch lock mounting plate. Just to be clear, you completely cut the original wires leading to the stock sensor that is still bolted beneath the intake plenum, right? The sensor is attached to the cylinder block, cylinder head or intake manifold. Problem stalling and not starting was not the sensor. With the hood open, standing by the drivers side front tire,you can see it by shining a flashlight at the opening under the intake manifold. I'm measuring the mpg to see if there is a difference, as owners reported better mpg after doing the fix. One mehanic sais they would fix it and then see if that takes care of it.
