What is P0328 fault code and what does it mean? What is the Knock Sensor 1 Circuit High Input Bank 1 failure description? How can you fix the P0328 error code? What are the causes and symptoms of the P0328 error code?

What is the P0328 fault code? What does it all mean?

An abnormal combustion, such as pre-ignition or detonation, can cause a misfire. This “misfire” can be caused by too early ignition timing, low-octane fuel or high engine operating temperatures.

The purpose of the knock sensor, is to monitor the knocks and relay the relevant information to vehicle’s main computer. If the voltage signal sent by the sensor is not within the specified range, a P0328 fault code will be issued.

Knock sensors can be used to detect engine knock. This sensor is typically 2-wire. Some sensors can be used with only one wire. It uses a 5 volt reference voltage. The sensor sends a voltage signal (informing the PCM of the severity) to the PCM when it detects engine misfires. This information is used to adjust the ignition timing and prevent misfires by the PCM. If the knock sensor sends a high voltage signal (above 2.5V), the PCM stores its P0328 fault codes in its memory. “Bank 1” is the bank in which the engine’s number 1cylinder is located.

What is the P0328 Fault Code?

  • – Defective knock sensor
  • – The knock sensor circuit is not working properly (damaged wiring, loose connections).
  • – Defective EGR system
  • – Defective cooling system
  • Poor air/fuel mixture
  • – Wrong octane fuel
  • – Low fuel pressure
  • – Internal engine problems
  • Problem with the PCM

 

What are the symptoms for P0328 fault code?

  • – Illumination for the check engine light
  • – Engine sounds during acceleration
  • Engine running hotter that normal
  • – Engine losing power
  • – Unsteady RPM

 

How to Fix the P0328 Fault Code

  • – Repair or replacement for the knock sensor harness
  • – Replacing Bank 1 Sensor 1’s knock sensor
  • – Replacing a damaged PCM
  • – Fixing fuel problems
  • – Repair the engine that has been overheated and check the cooling system

 

How serious is the P0328 fault code?

It is possible to drive the vehicle to a safe location even if the code P0328 has been triggered. Although the symptoms are generally mild, it is important to fix any check engine lights that come on as soon as possible. Code P0328 indicates a possible mechanical engine problem or engine overload. You should take extra care when driving if you notice these symptoms.
