DTC DETECTION LOGIC

NOTE:

If DTC P0340 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to EC- 353, "DTC Logic".

DTC No.	CONSULT screen terms (Trouble diagnosis content)	DTC detecting condition	Possible cause
P0335	CKP SEN/CIRCUIT (Crankshaft position sensor вЂњAвЂќ 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 running.	Harness or connectors [Crankshaft position sensor (POS) circuit is open or shorted.] Crankshaft position sensor (POS) Signal plate

DTC CONFIRMATION PROCEDURE

1.PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

Turn ignition switch OFF and wait at least 10 seconds.
Turn ignition switch ON.
Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 10.5 V with ignition switch ON.

>> GO TO 2.

2.PERFORM DTC CONFIRMATION PROCEDURE

Start engine and let it idle for at least 5 seconds.

If engine does not start, crank engine for at least 2 seconds.
Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-277, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CRANKSHAFT POSITION (CKP) SENSOR (POS) POWER SUPPLY

Disconnect crankshaft position (CKP) sensor (POS) harness connector.
Turn ignition switch ON.
Check the voltage between CKP sensor (POS) harness connector and ground.

Is the inspection result normal?

Is the inspection result normal? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK CKP SENSOR (POS) POWER SUPPLY CIRCUIT

Turn ignition switch OFF
Disconnect ECM harness connector.
Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.

Also check harness for short to ground.

Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.

NO >> Repair or replace error-detected parts.

3.CHECK CKP SENSOR (POS) GROUND CIRCUIT

Turn ignition switch OFF.
Disconnect ECM harness connector
Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.

Also check harness for short to power

Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace error-detected parts.

4.CHECK CKP SENSOR (POS) INPUT SIGNAL CIRCUIT

Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.

Also check harness for short to ground and to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK CRANKSHAFT POSITION SENSOR (POS)

Check the crankshaft position sensor (POS). Refer to EC-279, "Component Inspection [CKP Sensor (POS)]".

Is the inspection result normal? YES >> GO TO 6.

NO >> Replace crankshaft position sensor (POS). Refer to EM-33, "Exploded View".

6.CHECK GEAR TOOTH

Remove crankshaft position sensor (POS). Refer to EM-33, "Exploded View".
Look into the mounting hole of
the crankshaft position sensor (POS) to check that there is no missing gear tooth in the signal plate 1.

Is the inspection result normal?

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Replace the signal plate. Refer to EM-90, "Exploded View" (M/T) or EM-92, "Exploded View" (CVT).

Component Inspection [CKP Sensor (POS)]

1.CHECK CRANKSHAFT POSITION SENSOR (POS)-1

Turn ignition switch OFF.
Loosen the fixing bolt of the sensor.
Disconnect crankshaft position sensor (POS) harness connector.
Remove the sensor.
Visually check the sensor for chipping.

Is the inspection result normal? YES >> GO TO 2.

NO >> Replace crankshaft position sensor (POS). Refer to EM- 33, "Exploded View".

2.CHECK CRANKSHAFT POSITION SENSOR (POS)-2

2.CHECK CRANKSHAFT POSITION SENSOR (POS)-2

Check the resistance between crankshaft position sensor (POS) terminals as per the following.

Is the inspection result normal?

Is the inspection result normal? YES >> INSPECTION END

NO >> Replace crankshaft position sensor (POS). Refer to EM-33, "Exploded View".
