Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC P0327, P0328 KS

DTC P0327, P0328 KSPFP:22060
Component DescriptionEBS010ZA
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 LogicEBS010ZB
The MI will not light up for these self-diagnoses.
DTC Confirmation ProcedureEBS010ZC
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
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-690, "
Diagnostic Procedure"
.
WITHOUT CONSULT-II
1. Start engine and run it for at least 5 seconds at idle speed.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to EC-690, "
