P0325 NISSAN - Knock Sensor Circuit Malfunction

Repair Importance Level: 1/3
Repair Difficulty Level: 2/3  What does this mean?

P0325 NISSAN Possible Causes

  • Faulty Knock Sensor
  • Knock Sensor circuit poor electrical connection
  • Knock Sensor harness is open or shorted
  • Faulty Engine Control Module (ECM)

First diagnose P0325 NISSAN code

    Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.

P0325 NISSAN Tech Notes

The P0325 code means that the Knock Sensor is not working properly. Problems with the knock sensor will not cause an engine performance problems. Replacing the knock sensor usually takes care of the problem.

Cost of diagnosing the P0325 NISSAN code

    Labor: 1.0

    The cost of diagnosing the P0325 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

When is the P0325 NISSAN code detected?

When an excessively low or high voltage from the sensor is sent to Engine Control Module (ECM)

P0325 NISSAN Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Possible Lack/Loss of Power

P0325 NISSAN Meaning

The Knock Sensor (KS) senses engine knocking (also known as detonation or pinging) using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold. 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). The ECM uses this signal to retard the ignition timing and protect the engine from this damaging pre-ignition.
