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.
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.
There are no symptoms. The knock sensor is a passive part that does not do anything if it's not activated. Knock sensors codes on the Villager/Quest are usually caused by some other component, not the sensor itself.
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.
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.
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.
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.
It is right on top of the block, you have to remove the manifold and fuel injectors to get to it.
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.
The knock sensor on a 1998 Nissan Quest is typically located on the engine block, usually on the driver's side, near the cylinder head. It may be positioned between the intake manifold and the engine block. To access it, you may need to remove some components, such as the intake manifold or other parts obstructing access. Always consult a repair manual for your specific model for precise details.
Where is the crankshaft sensor located
Never mind, I got my answer.
