CEL code P0328 knock sensor 1 circuit high bank 1 or single sensor

[th3rods]

Whats good team mazda3,

i have CEL code which turns up as :
P0328 knock sensor 1 circuit high bank 1 or single sensor

Has anybody ran into this issue before? If so, what was the exact cause of the issue?

Have a 2005 mazda 3 hatch auto. let me know your thoughts mazda3 world.

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Powertrain Control Module (PCM)

Possible solution
- Repair or resecure harness or connector
- Replaced knock sensor

When is the code detected?
- An excessively high voltage from the sensor is sent to Powertrain Control Module (PCM) or Electronic Control Module (ECM)

P0328 Description:
The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

also, what the solution/fix was to get it gone. this is my only CEL light as i've fixed 3 out of the 4 as a result of changing the purge valve, now its just this knock sensor.

thanks

iinteresting.

i also read that on a few google searches for this. thanks for the description, really appreciate it.

you think i can do this myself? i guess i'd just need a description of how to get to the knock sensor and troubleshoot the right areas ... i jsut dont even know where to begin lol

replaced knock sensor on car and it is now gone.
went through jimmy and charged me 180 for the labor. great guy, this jimmy. recommend him to do any mazda related work.
