DescriptionINFOID:0000000003856619
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.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
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 10 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and run it for at least 5 seconds at idle speed.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-215, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003856621
1.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E38. Refer to Ground Inspection in GI-37, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK KNOCK SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Disconnect knock sensor harness connector and ECM harness connector.
2. Check the continuity between knock sensor harness connector and ECM harness connector.
DTC No.Trouble diagnosis

P0335 CKP SENSOR (POS)
P0335 CKP SENSOR (POS)
DescriptionINFOID:0000000003856623
The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
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 10.5 V with igni-
tion switch ON.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for at least 5 seconds.
If engine does not start, crank engine for at least 2 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?

DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P0335Crankshaft position sen-
sor (POS) circuit The crankshaft position sensor (POS) signal
is not detected by the ECM during the first
few seconds of engine cranking.
The proper pulse signal from the crankshaft
position sensor (POS) is not sent to ECM
while the engine is running.
The crankshaft position sensor (POS) signal
is not in the normal pattern during engine run-
ning. Harness or connectors
