What Does DTC Code P0325 Mean?

If you have code P0325 from your car’s scanner, it means that your Engine Control Module (ECM) is getting a reading from the knock sensor which is way outside of the normal range.

While the problem may be with the engine itself, usually, something is wrong with the circuit or sensor. Problems with circuits or sensors can cause incorrect readings.

However, when the code appears, your ECM will default to the preset value, and you will be able to continue driving your vehicle with visible symptoms.

What are the Symptoms of Code P0325?

While you will always get a check engine light with code P0325, engine sound is often one of the signs too. Below I list the four most common symptoms of code P0325 to help you diagnose the problem and get your vehicle running normally again.

1 – Check the engine light
While it may seem exaggerated that the engine light is an indicator of an engine symbol, sometimes it is the only visible sign.

Although it is rare, it is not uncommon for unsuspecting drivers to see symptoms other than the blinking of the check engine light on the dashboard.

2 – Noise when speeding
When your car has a knock sensor symbol, it automatically returns to the default value. While this helps protect the engine from further damage it also reduces this lag time especially noticeable during acceleration.

If you’re listening, you may hear ping as you pick up speed. The longer this problem is left unresolved, the harder it will become.

3 – Increased walking noise
Although noise is most common during acceleration, it can be heard whenever the engine is running. This is especially true if you have code P0325 due to basic engine conditions rather than faulty knock sensors.

If you hear an unusual engine beep while the engine is idle, you must immediately take your vehicle for repair. Failure to do so quickly could cause additional damage to your device.

4 – Decreased engine performance
When your machine defaults to preset values, one of the first things that need to be done are the performance of the machine. You will see a noticeable decrease in your acceleration capability, but you will also experience a reduction in fuel economy.

As bad as it may sound, it gives you more time to get your vehicle to the repair shop before any further damage occurs.

This results in code P0325

While the most common cause of code P0325 is a faulty sensor, this is not the only thing that can cause you trouble. Below, we have highlighted the 4 most common causes of code P0325 that you should check before attempting to replace any part.

1 – Defective adjustment sensor
A faulty knock sensor is the most common symptom of engine code P0325. When the check engine light is illuminated, the ECM is falling behind the standard value, which is the reason for low engine performance and engine noise may occur.

2- Wiring problems
It doesn’t matter if the sensor is working properly if there is excessive wear or torn wires. It’s not uncommon for a mechanic to spend days driving himself crazy trying to figure out what happens when there is a problem with the wiring.

3- EGR system failure
Not only does the EGR system produce emissions – it keeps your engine performing at its best. But when things don’t go their way, it is not uncommon for a motor to start making unnecessary noise.

When this happens, code P0325 can be generated. The sensors work the way they should – your device is making sounds that should not be audible.

4 – Excessive blow to the engine
Just as a faulty EGR system can cause an engine to sound, many conditions can cause excessive engine noise. Defective components, poorly timed motors, and pressure leaks are just a few of the problems that can occur.

However, keep in mind that code P0325 usually appears only when the reading is far from the normal reading. So clicking a little on the device will usually not cause this code.

Is code P0325 dangerous?

P0325 code is a very dangerous machine code. If you leave the engine code P0325 the same and continue driving your vehicle, the problem will only get worse. Also, you can expect the code to have a negative impact on the performance of your vehicle.

This means that even if you are lucky and the damage does not get worse right away, you can still have an accident because your vehicle is running abnormally.

If you have the P0325 code, don’t delay bringing it to the store, you will only order more significant problems.

How to fix

While the only surefire way to replace the correct part the first time is to install a car scanner and see exactly what happens, if you want to sink in and save some bucks, you can try replacing the pump. Sensors Hopefully this is the problem.

If not, you will need to start with some more troubleshooting. Double-check the wires and use a multimeter to determine if you have excessive resistance in the circuit and make sure you have the power when it should be.

If you still cannot find the cause of your problem, you may need to take it to a mechanic. They will be able to install all the correct diagnostic equipment to better see what is happening inside your machine.
