What usually causes it
- A failed knock sensor
- A short in the wiring
- A loose part or engine noise that the sensor picks up
- A fault in the engine computer, which is not common
Knock is a pinging sound when fuel burns at the wrong time, and the knock sensor listens for it. The signal from the sensor on bank 1, or the only one on the engine, is higher than it should be.
We rate P0328 as OK to drive, fix when convenient, as a starting point. Keep an eye on the signs below. If the light starts flashing, stop driving soon.
