Code P0328 2005 Nissan Pathfinder Description

The P0328 diagnostic trouble code (DTC) for a 2005 Nissan Pathfinder indicates a high input signal from the knock sensor on Bank 1. The knock sensor is a crucial component that detects abnormal combustion in the engine, known as knocking or pinging. When the knock sensor detects these vibrations, it sends a signal to the engine control unit (ECU) to adjust the ignition timing and prevent engine damage.

  • Hi, I had my timing chain done, will this cause this code to come up if it was an issue with the timing. 05 pathfinder. Vehicle turn on and ran fine for a good 20m but then stall out and now this code. Would like your feed back thanks.

  • Unfortunately the problem is more than likely with the timing chain installation. It's really difficult to set the timing on that engine. The code may set because the timing was set too advance.
