On a 2000 Quest it is buried in the V between the front and rear cylinder banks.
I would make sure it is the real problem before replacing. the sensor alone is $175 and the gaskets are $50. I was quoted 5 hours labor, so apply an appropriate labor charge and it is not inexpensive.
In my case, a misfire only when the engine was hot resulted in an error code for the knock sensor. I replaced the sensor and still have the same problem.
I erased the error code for the knock sensor and it has not come back, but a new error code implied the crank position sensor ($30) was bad. I replaced that sensor but the misfire when hot is still there.
now there are no error codes so I have no clues as to the real problem.
If you go to a dealer, I would insist on ;
a. getting a print out of any and all error codes currently stored in the ECM
b. allowing only the work which you have personally approved
c. getting a written guarantee that the work will fix the problem
too many dealers do not do a good job of analyzing the real problem, fix something unrelated and then say, well, it needed replacing anyway.
I AM GETTING A OBD CODE ERROR FOR MY 2000 NISSAN QUEST , PO141 AND PO325 ??? HOW DO I FIX IT..
To replace the knock sensor on a 1999 Nissan Quest, first, disconnect the battery to ensure safety. Then, locate the knock sensor, which is typically situated on the engine block. Remove the electrical connector and unbolt the sensor using the appropriate socket or wrench. Install the new sensor, reconnect the electrical connector, and reattach the battery before starting the engine to check for proper operation.
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 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.
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.
If just the knock sensor need to be replaced. I would say no more than $150.00
Code P0325 in a Nissan Quest indicates a problem with the knock sensor circuit, specifically related to the knock sensor's performance or voltage. This can be caused by a faulty knock sensor, damaged wiring or connectors in the circuit, or issues with the engine control unit (ECU). The knock sensor is responsible for detecting engine knock or pre-ignition, and if it fails, it can affect engine performance and efficiency. Diagnosing the issue often requires checking the sensor, wiring, and connectors for faults.
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.
It is behind the intake manifold on the left side of the engine. It will take almost 6 hours to replace this cheesy part ($120) and cost about $500 in labor alone.
the Knock sensor is located behind the Harmonic balancer pulley. on the bottom sidethe sensor is $95.00 remove the lock down screw unplug and replace
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.
