GO TO STEP 2 .
NO
Replace 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 illustration.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.
