You can't always hear the knock that the sensors pick up. However, I would look at the 'pedal placement' first cause that could cause knock. Try cleaning or replacing (cheap) your TPS (throttle Position Sensor). It's the black sensor bolted to your throttle body. Some TPS bolt holes are elongated so you can adjust them - yours may just be loose and need adjusting.

Once that is figured out - I bet your knocking issue goes away, but let us know if it doesn't.

Common Problems That Trigger the P0327 Code
  • Defective Knock Sensor
  • Defective Knock Sensor Circuit or connections
  • Defective EGR System

If knock sensor damage can start the vehicle


The knock sensor was designed as a listening device for the vehicle's engine. It is used to detect engine noises such as detonation, when fuel ignites in an engine's cylinder, as well as adjusts the ignition timing when the vehicle is being driven. When a knock sensor is not working properly, it may cause permanent engine damage. Therefore, there are various symptoms to aid in recognizing a faulty knock sensor.

P0325 what does it mean


P0325: Knock Sensor 1 Circuit Malfunction Bank 1 or 1 Sensor

- Knock sensor circuit short to ground
- Knock sensor circuit short to power
- Knock sensor circuit open
- Faulty knock sensor
- Faulty Engine Control Module (ECM)

Replacing the knock sensor usually takes care of the problem.

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM).

I have a code p0325 knock sensor 1, circuit bank 1 or single sensor problem


A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block.

This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0325 most likely means one or more of the following has happened:
* The knock sensor is faulty and needs to be replaced
* There is a wiring short/fault in the knock sensor circuit

Possible Solutions
* Check the resistance of the knock sensor (compare it to factory specs)
* Check for broken/frayed wires leading to the sensor
* Replace the knock sensor


Test it and tell us news.

Diagnostic code po325 what does this mean


Hi the error code relates to the PCM Knock Sensor Circuit

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly.

It does sound like the sensor may be bad, but you also need to check the wiring.
This information comes from:

How do I replace a knock sensor for a 1992 toyota camry v6 le


First, I would like to mention that most knock sensor codes are not caused by the knock sensors, but a mechanical problem with the engine. The knock sensors cannot differentiate between noises caused by mechanical problems like a bad pulley bearing, bad motor mount, noisy alternator bearings, etc. and spark knock. knock sensor codes are set when the computer has retarded the timing as far as possible to compensate for ignition ping (Spark Knock) and the noise still exists.

With that said, here are the instructions.

Remove the Intake Chamber assembly.
Disconnect Injector connectors.
Disconnect the heater hose from the Intake Manifold.
Remove the 9 bolts. 2 nuts, 2 plate washers and Intake Manifold assembly.
Remove right hand engine mounting stay and water outlet.
Disconnect the following hoses and connectors:
Radiator inlet hose.
Engine coolant reservoir hose.
Engine Coolant Temperature Sensor connector.
Engine Coolant Temperature Switch connector.
Ground strap connector.

Remove the 3 bolts and right hand mounting stay.
Remove the wire band.
Disconnect the water bypass hose from the inlet housing.
Remove the 2 bolts, 2 nuts, 2 plate washers and water outlet.
Remove the 2 gaskets.
Disconnect the Knock Sensor connectors.
Remove the Knock Sensors.

I failed the emisson's test. I have a 97 Nissan


P0136 indicates a bad O2 sensor. This reports poor emission performance back to the car's PCM (computer)
P0325 indicates a bad "Knock" sensor which would adversely effect drivability as far as performance is concerned. Only way to fix these 2 problems is replacement of the 2 components.

What should I check on a 97 Subaru Outback that shows a knock sensor code?


the knock sensor itself can be faulty if there is a code showing for it.

CEL lights only come on if a sensor fails its diagnostic, it is nothing to do with the particular sensors readings, but telling you the sensor itself is bad.

The knock sensor is a little microphone attached directly to the cylinder block side wall.
