DTC P0327, P0328 KS

DTC P0327, P0328 KSPFP:22060
Component DescriptionBBS005E9
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 ECM.
On Board Diagnosis LogicBBS005EA
The MI will not light up for these self-diagnoses.
DTC Confirmation ProcedureBBS005EB
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at

Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and run it for at least 5 seconds at idle speed.
3. If 1st trip DTC is detected, go to EC-166, "
