Table of contents

P1324 ACURA Possible Causes

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

How do I fix code P1324 ACURA?

  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 connector’s pins.

Tech Notes

  • The P1324 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 P1324 ACURA code

  The cost of diagnosing the P1324 ACURA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

When is the code detected

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

Possible Symptoms

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

P1324 ACURA Description

  The knock sensor is mounted on the cylinder block and detects engine knocking. The vibration caused by knocking are converted into electrical signals through the piezo ceramic element. The Engine Control Module (ECM) controls the ignition timing based on the electrical signals. If the signal from the knock sensor do not vary for a set time period, the ECM detects a malfunction and sets the P1324 code.
