P0325 Ignition/Distributor Engine Speed Input Circuit Intermittent

Are you experiencing issues with your car’s ignition system? Are you seeing a “Check Engine” light come on?

If so, you may be dealing with a P0325 error code, which indicates an issue with the engine speed input circuit. In this article, we’ll dive into what exactly this code means, what causes it, and what steps you can take to fix it.

What is the P0325 Error Code?

The P0325 error code indicates an issue with the engine speed input circuit in your car’s ignition system.

It specifically refers to a lack of signal coming from the crankshaft position sensor, which is responsible for monitoring the engine’s RPMs and sending that information to the engine control module (ECM).

When the ECM doesn’t receive a signal from the crankshaft position sensor, it can’t properly control the engine’s ignition timing and fuel delivery. This can result in poor engine performance, decreased fuel efficiency, and potentially even engine damage if left untreated.

What Causes the P0325 Error Code?

There are several potential causes of a P0325 error code, including:

  1. Faulty Crankshaft Position Sensor: The most common cause of a P0325 code is a faulty crankshaft position sensor. Over time, these sensors can become damaged or worn, causing them to fail to send signals to the ECM.
  2. Wiring Issues: It’s also possible that there are issues with the wiring connecting the crankshaft position sensor to the ECM. This can include damaged or corroded wires, loose connections, or even a short circuit.
  3. Failed ECM: In rare cases, the ECM itself may be the culprit behind a P0325 code. If the ECM has failed or is malfunctioning, it may not be able to properly receive signals from the crankshaft position sensor.

How Do You Fix a P0325 Error Code?

If you’re experiencing a P0325 error code, there are several steps you can take to fix the issue:

  1. Replace the Crankshaft Position Sensor: In most cases, the first step in fixing a P0325 code is to replace the crankshaft position sensor. This is a relatively simple fix that can be done at home or at a mechanic’s shop.
  2. Check the Wiring: If replacing the crankshaft position sensor doesn’t solve the issue, the next step is to check the wiring connecting the sensor to the ECM. Look for any signs of damage, corrosion, or loose connections, and repair or replace any affected wires.
  3. Check the ECM: If neither of the above fixes solve the issue, it’s possible that the ECM itself is faulty. This will require a more in-depth diagnosis and potential replacement of the ECM.


In conclusion, a P0325 error code can be a frustrating issue to deal with. However, with the right diagnosis and repair steps, it’s possible to fix the issue and get your car running smoothly again. Whether you choose to tackle the issue yourself or take it to a mechanic, be sure to address the issue promptly to prevent further engine damage.


  1. Can I still drive my car with a P0325 code?

While it’s technically possible to drive your car with a P0325 code, doing so can cause damage to your engine over time. It’s best to address the issue as soon as possible to prevent further damage.

  1. How much does it cost to fix a P0325 code?

The cost of fixing a P0325 code can vary depending on the cause of the issue and whether you choose to fix it yourself or take it to a mechanic. In general, you can expect to pay anywhere from $100 to $500 for parts and labor.

  1. How do I know if my crankshaft position sensor is bad?

Symptoms of a bad crankshaft position sensor can include rough engine idle, stalling, difficulty starting, and poor fuel efficiency. You may also see a “Check Engine” light come on.

  1. Can a P0325 code cause engine damage?

While a P0325 code on its own is unlikely to cause engine damage, driving with the issue for an extended period of time can cause problems with your engine’s ignition timing and fuel delivery, which can lead to further damage.

  1. How can I prevent a P0325 code from occurring?

Regular maintenance of your car’s ignition system and engine can help prevent issues like a P0325 code from occurring. This includes changing your spark plugs and ignition coils as needed, keeping up with oil changes, and addressing any potential issues promptly.
