The knock sensor detects spark knock or ping.
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
If a knock sensor was bad, the check engine light would be illuminated and the code(s) set would indicate so.
LS does not have a knock sensor. GSR does have a knock sensor
It is located on the side of the engine block. If you have a code for a knock sensor and you have a noise in the engine, it will set the code. That does not mean that the sensor is bad. They very rarely give problems.
Yes, a faulty knock sensor can lead to engine misfires and vacuum problems. The knock sensor monitors engine vibrations and helps the engine control module adjust the ignition timing to prevent knocking. If the sensor malfunctions, it may cause incorrect timing adjustments, leading to misfires, poor engine performance, and potentially affecting the vacuum system due to improper combustion. Addressing a bad knock sensor can help restore optimal engine function.

Where is the knock sensor for a 99 pathfinder
A 'knock sensor high input' error on a 2000 Subaru Impreza 2.5RS indicates that the engine control unit (ECU) is detecting a higher-than-normal voltage signal from the knock sensor. This sensor monitors engine vibrations to detect knocking or pinging, which can indicate pre-ignition or detonation issues. A high input may suggest a faulty sensor, wiring issues, or excessive engine noise, potentially leading to performance problems or engine damage if not addressed. It's advisable to diagnose the sensor and related components for proper function.
The knock sensor is located in the engine "V" under the upper and lower intake manifolds, and under the coolant crossover pipe. It requires considerable disassembly to get to. If you have a code for the knock sensor, be advised that the knock sensor is probably NOT the problem. Many problems will set the code for the knock sensor because they share part of the circuit. There are two oxygen sensors, one at the front where the exhaust pipe comes down and turns toward the back, and one behind the second converter, under the passenger seat.

I don't believe it has a knock sensor.
