Component Inspection

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.

RESISTANCE SPECIFICATION

Terminals	Resistance
1 and 2	6.7 - 7.7Ω
1 or 2 and ground	∞Ω (Continuity should not exist)

Is the inspection result normal?

YES : GO TO 2.

NO : Replace intake valve timing control solenoid valve.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove intake valve timing control solenoid valve.
2. Provide 12V 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 Fig 1.
  CAUTION: Do not apply 12V 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.
