DTC Advanced Diagnostics: P0328
DTC P0328:Knock Sensor 1 (Bank 1) Circuit High Voltage (Engine Type: J35Y1, J35Y2)

General Description

The knock sensor 1 (bank 1) is mounted on the engine block and detects engine knocking. The vibrations caused by the knocking are converted into electrical signals through the piezo ceramic element. The powertrain control module (PCM) controls the ignition timing based on the electrical signal. If the signal from the knock sensor 1 (bank 1) is a specified voltage for a set time, the PCM detects a malfunction and stores a DTC.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

PCM internal circuit failure

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
