Step 10
Use scan tool to confirm whether the DTC code is stored again.
(a) Connect scan tool to the datalink connector.
(b) Turn the ignition switch to "ON" position.
(c) Clear DTC code.
(d) Start and run the engine at idle speed to warm up the engine
for at least 5 min.
(e) Road test the vehicle for at least 10 min.
(f) Read control system DTC code again to confirm that the
system has no DTC code.
No
Intermittent Fault. Refer to 2.2.7.3 Intermittent
Fault Check
Yes
Step 11
Diagnostic completed.
5. Repair Instructions:
Replace crankshaft position sensor. Refer to 2.10.8.2 Crankshaft Position Sensor Replacement .
2.2.7.30 DTC P0327 P0328
1. DTC Descriptor:
DTC P0327 Knock sensor signal circuit voltage is too low
DTC P0328 Knock sensor signal circuit voltage is too high
KS sensor to ECM feedback signal helps ECM control the ignition timing to achieve the optimal operation and the ignition system
to achieve the best performance, as well as to prevent damage to the engine by a potential knock. KS sensor is located below the
intake manifold on the cylinder. KS sensor voltage changes with the AC signal generated by the vibration with running engine. Engine
control module adjusts spark timing according to KS sensor signal amplitude and frequency.
ECM receives signals from KS sensor harness connector EN08 terminal No.1 and 2 through ECM harness connector EN01 terminal
No.30 and 31.
