Diagnostic Test
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
- Turn ignition switch OFF.
- Disconnect intake valve timing control solenoid valve harness connector.
- Check resistance between intake valve timing control solenoid valve terminals as follows.
Terminals Resistance (Ω) 1 and 2 7.0 - 7.7 [at 20°C (68°F)] 1 or 2 and ground ∞
(Continuity should not exist)
Is the inspection result normal?
YES
GO TO STEP 2 .
NO
Replace malfunctioning intake valve timing control solenoid valve. Refer to EXPLODED VIEW .
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
- Remove intake valve timing control solenoid valve. Refer to EXPLODED VIEW .
- Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Make sure that the plunger moves as shown in the figure below.
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve.
NOTE:Always replace O-ring when intake valve timing control solenoid valve is removed.
Is the inspection result normal?
YES
