Component InspectionNCEC0212KNOCK SENSORNCEC0212S01IUse an ohmmeter which can measure more than 10 MW.
1. Disconnect knock sensor harness connector.
2. Check resistance between terminal 2 and ground.
Resistance: 500 - 620 kW[at 25ÉC (77ÉF)]
CAUTION:
Discard any knock sensors that have been dropped or physi-
cally damaged. Use only new ones.

Component DescriptionNCEC0206The 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.
Freeze frame data will not be stored in the ECM for the knock
sensor. The MI will not light for knock sensor malfunction. The
knock sensor has one trip detection logic.
ECM Terminals and Reference ValueNCEC0207Specification data are reference values and are measured between each terminal and 48 (ECM ground).

DTC Confirmation ProcedureNCEC0209NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 9 seconds
before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that bat-
tery voltage is more than 10V at idle.
With CONSULT-II
1) Turn ignition switch ªONº and select ªDATA MONITORº mode
with CONSULT-II.
2) Start engine and run it for at least 5 seconds at idle speed.
3) If DTC is detected, go to ªDiagnostic Procedureº, EC-SR-232.
With GST
Follow the procedure ªWith CONSULT-IIº above.
