Bypassing the knock sensor on a 1999 Nissan Quest is not recommended, as it can lead to engine damage and affect performance. If you're experiencing issues with the knock sensor, it's better to troubleshoot and fix the underlying problem rather than bypassing it. This may involve replacing the sensor or checking the wiring and connections. Always consult a professional mechanic for the best course of action.
I AM GETTING A OBD CODE ERROR FOR MY 2000 NISSAN QUEST , PO141 AND PO325 ??? HOW DO I FIX IT..
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.
not easy, it's under intake manifold between the heads. Have to take off plenum, water bypass pipes. it's the only electrical wire on the top of the block!
The Nissan gurus put the knock sensor on the car for a reason. Unfortunately it uses the engine block for the ground and only one wire of the two in the harness is live. The knock sensor is not the easiest piece of equipment to get to so many people either live with the knock sensor being bad or bypass it. Once you get to the sensor, you can clean the engine block and the bottom of the sensor and reinstall. That cures the problem in many cases. The most effective safe way to fix the knock sensor is to replace it. If you want to take your chances you can research knock sensor bypass in your favorite search engine. There are a lot of articles with step by step directions so I doubt the procedure needs to be repeated here.
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.
yes
The knock sensor is located below the intake manifold
