What causes a shorted knock sensor on a Nissan?
But I can say that the scenario for a shorted knock sensor (a common failure on Nissan V-6 engines) to cause a fault code P0500 for a Vehicle Speed Sensor would involve a rodent eating wire insulation off of your engine harness causing some crossed wires. Or some other strange thing.
Can a faulty knock sensor cause a check engine light to come on?
The faulty knock sensor will not cause the Check Engine light to come on nor will it cause the driveability symptoms you describe. The cost for knock sensor replacement is that high because it involves removing the upper and lower intake manifolds for access.
How do you remove a knock sensor from a car?
Remove the wiring harness from the knock sensor by squeezing in on the tabs that hold the connector in place and pulling the harness away from the sensor. Move the wiring harness to one side. Remove the sensor holding bolt with an adjustable wrench turned in a counterclockwise direction. Pull the sensor from the engine block by hand.
When do I need to replace the spark knock sensor?
The spark knock sensor will adjust your engine’s timing automatically when detonation is detected. If your engine is knocking or pinging, you may need to replace your spark knock sensor.

Is the Nissan speedy knock sensor still working?
If playback doesn’t begin shortly, try restarting your device. An error occurred. Please try again later. (Playback ID: h57amo9ed2lHCukR)

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. Several other mechanics around town tell me that they are wrong and I do need to replace it. Does anyone have any input on this?
Why does my Nissan club not detect engine knock?
If the engine is running properly, it vibrates the same regardless of worn motor mounts. The mounts just help to isolate the vibration from the cabin. Relocating the KS to get rid of the DTC is one thing but relocating it to where it cannot detect engine knock defeats its purpose.
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.
Why does my Lexus RX 300 not have a knock sensor?
Funkyfresh September 6, 2017, 4:03pm #1 So my 99 lexus rx 300 with 200K+ is throwing the codes for both knock sensors. This most likely means that the wiring harness is bad.
What is the code for the knock sensor?
The code is 0325 which is saying the sensor is faulty, not that it’s just detected knock. I would love to dream up some other reason as to why my problem is happening, and I usually do, but this seems pretty straight forward. Without removing the knock sensor and testing what more diagnosis would you recommend?
Is there a knock sensor problem on my Hummer?
In fact, if you have a 4.8 L 5.3 L or 6.0 L in any General Motors vehicle, including a Hummer or Pontiac, you will probably run into a check engine light indicating a defective knock sensor at some point.The check engine light registering a code P0332 or a P0327 is often the first sign you have this common problem.
What are the codes for the knock sensor?
Eventually this turns on the check engine light and sets the codes P0332 and P0327. Note that often either one or the other code will set. Regardless if one or both codes are set, not only should the two original knock sensors be replaced, but you should also replace the harness.
Why is the knock sensor on my car only one wire?
If drive around with the check engine light on when a code P0332 or a P0327 is set in the computer memory, engine damage could occur. To me the most interesting part about the knock sensor is that it only has one wire going to it. The reason for this is the sensor generates its own voltage and is case grounded.
Where are the knock and Ping sensors located?
It’s a piezoelectric automotive sensor that produces a small voltage signal when it hears internal engine noise that we often call knock and ping. This is why the location of the two sensors is a problem. In order to hear the engine noise reliably the sensors are buried under the intake manifold.
Is it safe to drive a 2004 Nissan Xterra?
I have a 2004 Nissan Xterra that has been chugging for a few months now. The problem is intermittent and only happens about once or twice a week when driving, but when it starts to chug (feels like it is running out of gas, jerky, will not accelerate) it is unsafe to drive on the freeway.
How to relocate the knock sensor in a Nissan Pathfinder?
Step by step process for relocating the knock sensor in a 1999 Nissan Pathfinder to avoid the tedious task of taking the air plenum off. Filming was done with my micro 4/3rd Panasonic GF-1 camera w/ 14-45mm lens. Loading…

Is there such thing as a bad knock sensor?
No such thing. Perhaps you could report the specific code. Note that NONE of these say “bad knock sensor” – the computer is clueless about the actual condition of the sensor itself. Its just a box of wires hooked by wires to other wires. That’s about it. I doubt your symptoms are from that though. You should troubleshoot the speed sensor code.
Can a shorted sensor cause a high voltage reading?
A shorted sensor will not cause a high voltage reading to be seen by the ECU. If anything, the reading will be near zero volts due to the short on the sensor line.
