VARIABLE VALVE TIMING ACTUATOR INSPECTION [ZJ, ZY]

id0110b7801200

Caution

•  The variable valve timing actuator cannot be disassembled since it is a precision unit.

1.  Disconnect the negative battery cable.

2.  Perform the following procedure.

Except U.K. specs.

1.  Remove the fresh-air duct and the air cleaner as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

U.K. specs.

1.  Set the air cleaner cover out of the way. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

2.  Remove the fresh-air duct and the air cleaner case as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

3.  Remove the ignition coils. (See IGNITION COIL REMOVAL/INSTALLATION [ZJ, ZY].)

4.  Disconnect the ventilation hose. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

5.  Set the vacuum hose out of the way. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, ZY].)

6.  Remove the cylinder head cover. (See TIMING CHAIN REMOVAL/INSTALLATION [ZJ, ZY].)

7.  Remove the splash shield (RH). (See DRIVE BELT REMOVAL/INSTALLATION [ZJ, ZY].)

8.  Verify that the camshaft knock pin hole of the variable valve timing actuator and the T- mark of the cover are aligned and fixed as shown in the figure.

•  If the camshaft knock pin hole and the T-mark of the cover do not align, rotate the crankshaft two times in the direction the engine rotates, and then verify that they are aligned.

―  If it does not align, replace the variable valve timing actuator.

•  If under any condition the variable valve timing actuator makes a hitting noise directly after the camshaft exceeds maximum lift while rotating the crankshaft two times in the direction of engine rotation, replace the variable valve timing actuator as it has not been fixed.
