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

Can a bad knock sensor cause a tranny to go stay in 2nd gear(limp mode)on a 2008 dodge ram 3.7 liter.Got 2 codes a #2 knock sensor and tcm power low voltage


The transmission is in limp-in mode because of the second DTC - TCM (transmission control module) low voltage. The knock sensor code has nothing to do with that. You need to have the TCM and transmission checked out.

Knocks, Low Power

Maxima got a knocking noise by the power steering pump just replace the rod bearings and still knocks down by the power steering pum


You replaced the rod bearings, were they knocking?
Also, you have wrist pins that connect the piston to the rod, if one is bad it will knock and sound like a bearing.

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).

What causes a p 0327 diagnostic code on a 95 contour


P0327 - Knock Sensor 1 Circuit Low Input Bank 1 or Single Sensor
First check the knock sensor connector. If the connector is clean and secure, replacing the knock sensor usually takes care of the problem.

- An excessively low voltage from the sensor is sent to Powertrain Control Module (ECM) or Engine Control Module (ECM)

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 Powertrain Control Module (PCM) or Engine Control Module (ECM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).


Test and check it. Hope helps.

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

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.

What is a knock sensor? And could this cause a car to lose power?(2002 Kia Spectra)


A knock sensor is simply a microphone that is screwed into the engine block. It is there to listen for pinging or engine "knock" that is caused by poor fuel or extreme load. When the computer hears the knock, it retards timing, which in turn reduces the tendency for knocking, however, it will reduce power to a certain extent as well. It is possible that a faulty knock sensor can be telling the computer to ****** ignition timing too much, it is also possible that there is a mechanical problem within the engine that is mimicking the sound of knocking and retarding timing as well.
