P0325 Chrysler Code - Knock Sensor Circuit Malfunction
Quick Answer
A knocking vibration from the cylinder block is sensed as vibrational pressure by the Knock Sensor. Common causes include Faulty Knock Sensor, Knock Sensor circuit poor electrical connection, Knock Sensor harness is open or shorted. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0325 Chrysler Description
Engine knock occurs within a specific frequency range. The Knock Sensor, located in the engine block, cylinder head, or intake manifold, is tuned to detect that frequency.
Inside the knock sensor is a piezoelectric element. Piezoelectric elements generate a voltage when pressure or vibration is applied to them. The piezoelectric element in the Knock Sensor is tuned to the engine knock frequency.
The vibration from the engine knocking vibrates the piezoelectric element generating a voltage. The voltage output from the Knock Sensor is highest at this time.
What are the Possible Causes of the DTC P0325 Chrysler?
- Faulty Knock Sensor
- Knock Sensor circuit poor electrical connection
- Knock Sensor harness is open or shorted
- Faulty Engine Control Module (ECM)
