P0324 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The knock control system surveys the engine’s cylinders and transfers data signals to the PCM. The PCM makes use of this data to foretell when a knock occurs and repairs the fuel delivery, also ignition timing to the correct cylinder(s) and block any more chances of Knicks and misfires. If the knock control system experiences an error, the PCM fails to gather the correct data to achieve this, and it can lead to issues that involve engine knocking, pinging, and/or misfiring problems.

The knock sensor communicates with the engine control module (PCM) that the engine has an excessive juddering caused by an erroneous fuel and air mixture. The knock sensor fails to give a signal to the PCM, the P0324 will be set. The check engine light may be illuminated, or not be.

What causes this problem with the Random/Multiple Cylinder Misfire?

• Damaged knock sensor
• Negative electrical connection to the knock sensor circuit
• Bad, open, or shorted knock sensor harness
• Failed PCM (uncommon)

1. Knock Sensor - A bad knock sensor may not allow the engine to accelerate properly while driving on the highway, so it will cause the vehicle to lose fuel mileage. If you notice that this happens, you should have a certified mechanic inspect why the car is slow to accelerate.
2. Knock Sensor’s Circuit - Knock Sensor circuit is to send a message to the engine computer if one or more engine cylinders “knock”. This “knocking” is characterized by an explosion of the air-fuel mixture, which delivers less power and can eventually damage the engine. Check for any broken or frayed wires that lead to the sensor, otherwise, replace the knock sensor.
3. Knock Sensor Harness - A faulty knock sensor wiring harness can become defective due to heat coming from the engine. If the wiring harness is in bad condition, also if it’s hard to reach to the harness, and sensors, then have a mechanic put in new sensors while changing the harness to avoid this hassle down the line.
4. Knock Control System - The mechanic will first test the system for any stored codes using an OBD-II scanner. Then they will do a visual inspection to look for any problems with the wiring, connectors, harness, or the rest of the knock control system. They’ll then either use an oscilloscope or a knock sensor tester to determine whether the knock sensor is bad or if something else is going on.
5. Powertrain Control Module - A corrupted PCM could get erratic to a degree that your vehicle will have issues starting or may begin to stall when running. You will start to see that exhaust fumes have shorted when the car runs, emissions system control signals will begin to fail, so with a PCM that’s not working properly, you must it replaced instantaneously.
   

Interested to know why it’s very important to learn about the practical symptoms of this issue? Actually, it’s exceedingly important to learn of the common symptoms of the issue so that you can determine it. Take in mind, we’ll share some details on some effective symptrons of the OBD error code P0363.

Common Symptoms

• Check Engine Light illuminates
• Fuel efficiency decreases
• Idle is rough
• Acceleration is depraved or lost
  

These are helpful ways that will guide you in correcting the OBD Code P0324

• Designate a knocking, pinging, or misfiring engine problem
• Replace the knock sensor
• Repair a poor electrical connection to the knock sensor circuit
• Replace the wiring harness for the knock sensor
• Replace or reprogram the PCM (uncommon)

Do not sweat it if your OBD Code keeps on flashing on, as this is why we’re here to help. Take a look at our high-ranked variation of knock sensor, knock sensor circuit, knock sensor harness, knock control system, Power Control Module and so much more. Now all your problems would resolve in no time.

If desiring to make it effortless in diagnosing this trouble code, then please do follow the steps that are described below:

All methods of diagnosis must start with a detailed visual examination of electrical parts, for instance wiring and connectors. Any components that are loose, damaged, broken, open, or shorted, have to be replaced or repaired. This should clear the code, and a road test should be conducted on the vehicle to determine if the code is stored, once again. Commonly, reproducing the defect and code storage is a great way to make sure of the specific problem. If the P0363 code comes back, the mechanic will proceed with other probable fixes that will solve the issue.

Common Mistakes When Diagnosing the P0324 Code

At times, even for other codes that have been recorded before the P0324, there probably wasn’t anything in any way wrong with the knock sensor system. Actually, it may just be doing its duty by checking knocks within the engine. Constantly move on by repairing every code you will notice in whichever order it was documented to keep this issue from rising to the surface.
