Is there a way to bypass a knock sensor?
Your knock sensor is an electrical device on your truck, car or Sport Utility vehicle that detects knocks in your engine caused by premature detonation of the air-fuel mixture as it enters the cylinder head. If you ever need to bypass your knock sensors, the most direct way of doing so is to simply disconnect them.
Where is the knock sensor on a Nissan V-6?

Do you need to replace a knock sensor or not?
My last stop is replacing the knock sensor for $600, the problem is that the Nissan Mechanics (I visited two dealerships in different cities) told me not to replace this as it would not cause chugging.

Can a defective knowck sensor cause chugging power?
While it is theoretically possible for a defective knowck sensor to cause an unwanted ignition retardation and poor power, I don’t believe it can cause chugging. A knock sensor is a piezoelectric device tuned to a specific frequency to detect preignition pulses.
Is there a code for bad speed sensor?
There’s also no code that says “bad speed sensor.” http://www.obd-codes.com/p0500 But you also need to sort out the knock sensor issue – knocking is very bad for the engine.
