Replacing the knock sensor on a 2001 Nissan Quest is a moderately challenging job, typically requiring 3-5 hours of labor. The sensor is located beneath the intake manifold, which necessitates the removal of several components, making the process more involved. While a skilled DIY mechanic may attempt the replacement, it is advisable to have some experience with engine work. Professional assistance may be preferable for those unfamiliar with the procedure.
I AM GETTING A OBD CODE ERROR FOR MY 2000 NISSAN QUEST , PO141 AND PO325 ??? HOW DO I FIX IT..
The knock sensor on a 1998 Nissan Quest is also located under intake manifold and yes alot of work but can be done in a day. 120 dollar part and 500 labor at garage but for u at home mechanics just a simple side project.
Never mind, I got my answer.
On a 1997 Nissan Quest, the harness for the knock sensor is typically located on the engine block, near the intake manifold. You may need to remove the intake manifold to access the knock sensor more easily, as it is often positioned underneath it. The wiring harness should be connected to the sensor itself, which is usually found on the side of the engine. Always consult a repair manual for detailed diagrams and procedures specific to your vehicle.
The knock sensor sub-harness connector is located on the passenger side of the engine compartment next to the intake manifold. Must be checked by observing voltage fluctuations with a voltmeter.
The knock sensor is located below the intake manifold

On a 2002 Nissan Quest, the knock sensor is located on the engine block, typically on the driver's side. You may need to remove the intake manifold to access it, as it's positioned beneath that component. The sensor is usually mounted near the cylinder head, making it crucial for detecting engine knocking. Always refer to the vehicle’s service manual for precise location and removal instructions.
With mucho effort, that's how. The sensor is behind the intake manifold, throttle body ect, all of which must be removed. Labor alone will be 5-6 hundred , knock sensor another 150 or so. Good luck.
where is it located
40.00
on a 2001, with the 3.3, the knock sensor is under the water crossover pipes, which are under the intake manifold. Pain to change. Take off plenum, intake manifold and there it is, on top of the block between the heads.
