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).

Code p0325


P0325 Knock Sensor 1 Circuit Malfunction
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

What does mean p0325 and p0497 and Honda Accord 2005 V6?


Both the codes here are engine codes you need to be able to pull ABS codes. P0325 is a knock sensor code and the P0496 is evap purge flow high. These will not cause a ABS or Traction control problems.

Codes p0171 p0303 p0325 car missing


p0171 = fuel system too lean, this means vacuum leak or faulty oxygen sensor

p0303 = cylinder 3 misfire

p0325 = knock sensor malfunction.

p0303 and p0325 - i can see these working together, if a cylinder misfires, it will cause the knock sensor to trip. I would lean towards the coil and or ignition module, along with a faulty oxygen sensor.

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

A P0325 refers to the knock sensor electrical circuit, not the sensor itself! So check all wiring & connectors leading to the sensor, back to the PCM. Good luck, I found a good P0325 article here - http://www.obd-codes.com/p0325

Nissan quest 1999 engine light codes P0325 & P1105 WHAT DO THESE CODES MEAN


P0325 is for the knock sensor.

P1105 is for the manifold absolute pressure sensor (MAP).

In either case diagnostic tests need to be performed to rule out faulty sensors or if something else is causing the sensors to give the computer inaccurate information.

I need to troubleshoot dtc p0325 & p1320 on a 1997 Nissan Maxima GXE?


Hi,

The two codes seem to be related. The P0325 description is knock sensor circuit malfunction and the P1320 is ignition signal - circuit malfunction.

I'll summarize and then give links on more detailed articles I found. Basically the P0325 refers to the knock sensor and associated wiring. The P1320 refers to the ignition coil and wiring. Check the sensor, coil, and associated wiring.

I found some great articles:
P0325 - http://www.obd-codes.com/p0325
P1320 - http://autorepair.about.com/library/a/1i/bl039i.htm

Good luck!
