Title: 2ZR-FAE (ENGINE CONTROL): CONTINUOUSLY VARIABLE VALVE LIFT CONTROLLER: INSTALLATION; 2020 MY Corolla [01/2019 - 03/2019]

INSTALLATION

PROCEDURE

1. INSTALL CONTINUOUSLY VARIABLE VALVE LIFT CONTROLLER ASSEMBLY

HINT:

Perform "Inspection After Repair" after replacing the continuously variable valve lift controller assembly.

(a) Measure the protrusion length of the continuously variable valve lift controller assembly.

Standard Protrusion Length:

34.57 to 34.73 mm (1.36 to 1.37 in.)

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 protrusion length 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.

(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 installed. Make sure to remove the valve lift control actuator connector before installation.

(f) Install the valve lift control actuator connector to the valve rocker shaft assembly.

(g) Insert the continuously variable valve lift controller assembly into the camshaft housing sub-assembly.

(h) Install the continuously variable valve lift controller assembly to the camshaft housing sub-assembly with the bolt.

Torque:

18 N·m {184 kgf·cm, 13 ft·lbf}

NOTICE:

  • Make sure the O-ring is not caught between the parts.
  • If the continuously variable valve lift controller assembly has been struck or dropped, replace it.

(i) Install the wire harness clamp bracket to the camshaft housing sub-assembly with the 2 nuts.

Torque:

18 N·m {184 kgf·cm, 13 ft·lbf}

(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 2 screwdrivers, 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 sub-assembly or camshaft bearing cap.

(l) 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 straight pin while lightly prying the valve lift control actuator connector.
