There’s a knock sensor down (sensor 1, bank 1) that’s giving P0325. There are many reasons this code can be triggered, and your mechanic needs to diagnose it.

Your knock sensors only detect when the air/fuel mixture combusts prematurely or when your engine “knocks.” You’ll get less power, and the engine could get damaged if this happens for a long time.

A lot of NOx is released when a car engine “knocks.” If you get the trouble code P0325, knock sensor 1 in bank 1 isn’t working.

P0325 OBD-II Trouble Code: Knock Sensor Malfunction (Sensor 1, Bank 1)

The knock sensor circuit is the cause of ODB2 diagnostic trouble code P0325. A knock sensor code or a lean condition code may appear with this code.

An error code P0325 indicates that knock sensor 1 in circuit bank 1 is malfunctioning. When the knock sensor does not provide the correct information, the ECU will detect this malfunction. Consequently, the dashboard check engine light illuminates.

What Is A Knock Sensor?

Starting with ‘knock’ itself is probably a good idea. A pinking sound is produced when a mixture of air and fuel ignites at the wrong time (i.e., not due to a spark from the spark plug). Your engine can suffer if this happens repeatedly.

When Is The P0325 Honda Code Detected?

A sensor sends the Engine Control Module (ECM) an excessively low or high voltage. Piezoelectric elements are used to detect knocking (also known as detonation or pinging) in engines.

Sensors can be mounted on cylinder blocks, cylinder heads, or intake manifolds. Pressure from vibrations in the cylinder block is felt as knocking vibrations.

Engine Control Modules (ECMs) receive this voltage signal and convert it into a pressure signal. Using this signal, the ECM retards the ignition timing and prevents pre-ignition from damaging the engine.

How Serious Is The P0325 Code?

In general, a P0325 code is not a serious problem and can be safely driven to a safe location when it occurs. However, when the engine is knocking, some vehicles may experience a slight loss of engine power as the ECU retards timing to prevent damage.

What Are The Symptoms Of The P0325 Code?

• A person driving car with the P0325 code may not feel any symptoms at all.
• There may be a slight lack of power in the engine.
• One of the most noticeable symptoms is an illuminated Check Engine Light.
• What are the Possible Causes of the Code P0325 Honda?
• Issues related to electrical connections
• The wiring harness is open or shorted
• Failure of the knock sensor
• ECU failure

Finding The Cause Of The P0325 Honda Code

A code scanner is necessary for this. The procedure for using one of these code readers is very simple if you’ve never used one before:

You can find the OBD2 port by looking underneath the dashboard. In this case, the clutch pedal is to the left of and above it in the driver’s footwell.

• Connect the reader to the computer.
• Turn the ignition on.
• Since the reader gets its power from the car, it doesn’t need to be powered separately.
• Using the code reader, you can determine if any codes have been stored in your car’s ECU. 
• Several menus will need to be clicked through, so it isn’t entirely automatic. However, you can’t go wrong with this reader since it has only two buttons.
• The code(s) can be found by navigating through the menus.

How Does A Mechanic Diagnose The P0325 Code?

• Checks for codes using a scan tool—history, pending, and current codes may be present.
• It is important to note the freeze frame data for each of these codes, as this shows the vehicle’s conditions at the time the code was set, such as engine RPM, coolant temperature, run time, and vehicle speed.
• Resets the code so the diagnosis can be started over
• Tests the vehicle on the road to see whether the Check Engine Light comes back on and whether the problem is present
• During engine operation, uses a scan tool to ensure the knock sensor is functioning properly
• Tests the knock sensor for resistance
• Performs an ECU test in accordance with the manufacturer’s guidelines if necessary.

To accurately diagnose P0325, a scan tool that does more than check codes will be needed. With live data streams available through these scan tools, many items can be checked more quickly and accurately.

Common Mistakes When Diagnosing The P0325 Code

A technician who follows all the diagnostic steps or does them in order can make simple mistakes and overlook the basics of any code.

How Do I Fix Code P0325?

To determine what’s causing the knock sensor fault, it’s important to get it diagnosed.

It is recommended to find a Honda-certified shop nearby if you are not comfortable diagnosing the problem yourself. They will be able to pinpoint the problem and give you an accurate estimate for the repairs.

Code P0325 Honda Tech Notes

There is a problem with the Knock Sensor when the P0325 error code appears. There will be no performance problems associated with knock sensors. Usually, the problem can be resolved by replacing the knock sensor.

How Much Does It Cost to Fix Code P0325?

Several things can lead to P0325, including damaged wiring, a faulty knock sensor, and an overheating engine. The only way to give an accurate estimate is to diagnose the problem properly first.

Generally, shops will charge an hour for “diag time” (the labor time spent diagnosing your specific problem) when you take your car in for an inspection. This usually costs between $75 and $150, depending on the shop’s labor rate.

The diagnosis fee is usually applied to any required repairs if you have the shop perform the repairs. In that case, you can get an accurate estimate for repairs to fix your P0325 error code from a shop.

Possible Repair Costs for P0325

It may be necessary to perform one or more of the following repairs to resolve error code P0325.

Estimated repair costs include the cost of relevant parts as well as the labor required to perform the repair.

• Sensors for temperature range from $392 to $427
• Harnesses for knock sensors cost from $14 to $66
• The price of the knock sensor ranges from $297 to $381

Can I Still Drive With The Honda P0325 Code?

It is not necessary to worry about driving ability when dealing with trouble code P0325. Diagnostic Trouble Codes, like any other problem, should be dealt with promptly to ensure no further damage to the engine occurs. It is okay to drive for a short period of time.

Final Words

There is an electrical fault (short or open) in the wiring from the knock sensor to the ECM. The knock sensor is located between the two cylinder heads under the intake manifold. It is rare for them to fail. A rodent usually eats the single wire to the sensor when it gets in there.
