1ZR-FAE ENGINE CONTROL CONTINUOUSLY VARIABLE VALVE LIFT CONTROLLER INSTALLATION
PROCEDURE
1.INSTALL CONTINUOUSLY VARIABLE VALVE LIFT CONTROLLER ASSEMBLY
a.
*a
*b
Connector
Protrusion length
Measure the protrusion length of the continuously variable valve lift controller assembly.
HINT:
·
·
·
When reinstalling the continuously variable valve lift controller assembly, perform the measurement after the valve lift control
actuator connector is installed.
It is not necessary to perform this measurement when installing a new continuously variable valve lift controller assembly as the
protruding distance is 34.57 to 34.73 mm (1.36 to 1.37 in.).
If the protrusion length of the continuously variable valve lift controller assembly is not 34.57 to 34.73 mm (1.36 to 1.37 in.),
perform the Active Test and adjust the protrusion length to the specified value.

Standard Protrusion Length:
34.57 to 34.73 mm (1.36 to 1.37 in.)
b.

O-ring
*a
Protrusion
Install a new O-ring to the continuously variable valve lift controller assembly.
NOTICE:
·
·
Align the protrusion of the O-ring with the protrusion of the continuously variable valve lift controller assembly.
Make sure that the O-ring is not protruding from the groove in the continuously variable valve lift controller assembly.
c.
Rotate the crankshaft clockwise to retract the valve rocker shaft.
d.
Rotate the crankshaft clockwise again until the intake camshaft position at the No. 1 cylinder and No. 3 cylinder is as shown in the
illustration.
e.
Install the valve lift control actuator connector clip to the valve lift control actuator connector.
NOTICE:
Be sure to insert the protrusions of the valve lift control actuator connector clip into the holes in the valve lift control actuator connector.
HINT:
A new continuously variable valve lift controller assembly is supplied with the valve lift control actuator connector engaged. Make sure to
remove the connector before installation.
f.
Install the valve lift control actuator connector to the valve rocker shaft.
g.
Insert the continuously variable valve lift controller assembly into the camshaft housing.
h.
Place the wire harness clamp bracket onto the stud bolt.
i.
Install the continuously variable valve lift controller assembly to the camshaft housing with the bolt and 2 nuts.
Torque:
18 N*m (184 kgf*cm, 13 ft.*lbf)
NOTICE:
Make sure the O-ring is not caught between the parts.
j.
Using a screwdriver, slide the valve lift control actuator connector clip from the valve lift control actuator connector.
NOTICE:
Slide only the upper part of the valve lift control actuator connector clip as the straight pin will fall out from the bottom if the valve lift
control actuator connector clip is completely removed.
k.
Using a screwdriver, lightly pry the valve lift control actuator connector and align the hole in the valve lift control actuator connector with the
hole in the continuously variable valve lift controller assembly.
NOTICE:
·
·
Do not forcibly pry the valve lift control actuator connector.
Do not damage the camshaft housing or camshaft bearing cap.

Straight Pin
Insert the straight pin into the valve lift control actuator connector.
NOTICE:
Do not use a tool to insert the straight pin. Insert the straight pin by hand.
HINT:
If the straight pin is difficult to insert, insert the pin while lightly prying the valve lift control actuator connector.
m.
Using a screwdriver, install the valve lift control actuator connector clip to the valve lift control actuator connector.
NOTICE:
Insert the protrusion of the valve lift control actuator connector clip into the hole in the valve lift control actuator connector.
HINT:
Perform "Inspection After Repair" after replacing the continuously variable valve lift controller assembly.
