Why do that?
why are you asking.
is the ECU throwing DTCs for knock?
if yes, post the DTC, dont use the words we want the real TDC numbers.
even consider the engine is knocking?
try to think like a PCM
it is always listening to Mr. Knock microphone.
it is always adjusting spark timing to correct it.
what if it could not stop the knock?
(lean fuel mix>?)
a real ASE would see if the knock was real first.

when you use low octane fuel this sensor, allows the the
engine to adjust timing for the faster burning fuel.
it retards timing.
so do post ALL DTCs not just 1 of many.
and do check AFR.
AF/R Air fuel ratios.

all knock sensors
you , remove bolt and it comes off, (just look)
or it unscrews itself like other sensors, like oil pressure or ECT.
the fsm covers this, ever seen one>.?
id recommenced not not working on cars FSM free, sure would.
and for sure noobs.
and if a noob, there are vast dangers , working on cars, and worse.
alldata.com has this too.

if you have to ask how to remove or what it is, or where is it
that is all noob questions. they are ok.
but why not post all symptoms and DTC errors.
first.
then we can talk tests.
and how to gather evidence.

I changed the spark plugs, amd check engine light came on. p0328, knock sensor high output bank 1 ,, i changed the knock sensor and light went off for about 25 miles and came back on


Did you change the correct knock sensor? You may have other problems that the knock sensor is detecting, which means the knock sensor is operating correctly. Knock is usually caused by detonation (cylinder firing before intended). There are many reasons this can happen. A common one, is the cylinder is running too lean.

IGNITION KNOCK (DETONATION) SENSOR the knock sensor Is on the back of engine (driver side on LHD vehicles) under the cam position sensor. it is a giant PITA to change. i had to cut a wrench in half (7/8 i think??) and use a pry bar to break loose the sensor..

How do i change a knock sensor on a 1997 Nissan Altima?


Inspect/Test/Replace


A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark retard than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.

To replace the knock sensor:


  • Disconnect the knock sensor wiring connector.

  • Then, unscrew the sensor.

  • Remove the knock sensor.

  • Reverse the procedures to install the part.

My Jeep Liberty Has a 3.7 L V6, it has problems starting. A code popped up that was P0325? What does this code mean?


CARB (California Air Resources Board) has a consistent policy regarding monitoring knock (Ks) sensors but vehicle manufacturers don't have a consistent way of using knock sensor circuitry. There are generally two methods that manufacturers have for using the knock sensor.
In the first design, which is found in most vehicles, the knock sensor plays an active role in controlling ignition timing. In this system, the PCM is advancing ignition timing until knock occurs and then retards timing slightly. This system runs on the verge of engine knock at all times. In this system the function of the knock sensor circuit is critical. If the sensor malfunctioned, precise ignition timing control could not be achieved.

A "dead" sensor circuit would not be able to detect actual knock, timing would be overly advanced, and NOX exhaust emissions would increase. For this reason, manufacturers that use the knock sensor in this manner are required to monitor this sensor and light the MIL light when a malfunction is detected.

In the second design, the knock sensor plays a very passive role and is really only on the engine for protection purposes. The various engine sensors send their information to the PCM to determine ignition timing. The PCM uses this information to control the ignition timing based on look-up tables stored in its memory. If ignition knock is detected, the PCM will take action and ****** the timing a few degrees. This type of control is generally used to control spark knock caused by changes in fuel octane.

Used in this way, the knock sensor is less critical to emissions and may not even have a measurable emission impact. Unlike the first design, a "dead" knock sensor in this system will have little to no effect on the operation of the engine. Manufacturers that use this design are not required to monitor the sensor under EPA OBDII regulations and will not turn on the MIL if the P0325 DTC is set.
Remember, this sensor does not change the operation of the engine. The customer will not notice any change in the way the vehicle operates. The knock sensor system has a one trip detection logic and WILL NOT turn on the MIL or store Freeze Frame data.

How to Diagnose P0325

Most technicians know how this type of sensor operates. Its element produces a voltage when the sensor picks up a vibration, usually caused by engine detonation.Technicians then check the ohmic value of the sensor.
Maybe this was of some help.Your valuable feedback would be appreciated.Thanks for choosing Fixya.

2000 chevy silverado 5.3, skips a little between 50-55mph, plugs and wires were changed. scanner shows bad knock sensor #2. will changing this correct the problem?


it should but recheck ur wires and plugs first a bad plug or wire can cause a knock ping problem and set off sensor also check the knock sensor connections at rear of engine----- the knock sensors for the 8 cyl are located under the intake manifold so its labor intensive to replace the sensor

Where is the knock sensor located in 2000 chevy 5.3 v-8?


They are located below the intake manifold, you may have to remove the intake to change them. The sensors may be shot, they have a problem with water puddling in their mounting wells, after changing, seal the sensors with an RTV to keep water out of the wells

The Knock Sensor (KS) system detects engine pre-detonation. The Powertrain Control Module (PCM) retards the spark timing based on the signals from the knock sensors. The knock sensors produce an AC voltage when specific frequencies are detected. The knock sensor voltages are an input to the PCM. The amount of AC voltage produced is proportional to the intensity of the knock.
When you ****** timing fuel mileage goes down.
