Diagnosis Procedure
- CHECK EXHAUST VALVE TIMING (EVT) CONTROL POSITION SENSOR POWER SUPPLY
- Turn ignition switch OFF.
- Disconnect exhaust valve timing (EVT) control position sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between EVT control position sensor harness connector and ground.
+ - Voltage (Approx.) EVT control position sensor Connector Terminal F57 1 Ground 5.0 V Is the inspection result normal?
YES: GO TO 3.
NO: GO TO 2.
- CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to "DIAGNOSIS PROCEDURE ".
Is inspection result normal?
YES: Perform the trouble diagnosis for power supply circuit.
NO: Repair or replace error-detected parts.
- CHECK EVT CONTROL POSITION SENSOR GROUND CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between EVT control position sensor harness connector and ECM harness connector.
+ - Continuity EVT control position sensor ECM Connector Terminal Connector Terminal F57 2 F24 42 Existed - Also check harness for short to power.
Is the inspection result normal?
YES: GO TO 4.
NO: Repair or replace error-detected parts.
- CHECK EVT CONTROL POSITION SENSOR INPUT SIGNAL CIRCUIT
- Disconnect ECM harness connector.
- Check the continuity between EVT control position sensor harness connector and ECM harness connector.
+ - Continuity EVT control position sensor ECM Connector Terminal Connector Terminal F57 3 F24 43 Existed - 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.
- CHECK EVT CONTROL POSITION SENSOR
Check the EVT control position sensor. Refer to "COMPONENT INSPECTION (EVT CONTROL POSITION SENSOR) ".
Is the inspection result normal?
YES: GO TO 6.
NO: Replace EVT control position sensor. Refer to "REMOVAL AND INSTALLATION ".
- CHECK CAMSHAFT (EXT)
Check the following.
- Accumulation of debris to the signal plate of camshaft rear end
- Chipping signal plate of camshaft rear end
Is the inspection result normal?
YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".
NO: Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to "REMOVAL AND INSTALLATION ".
