Camshaft Timing Control Motor: Installation

1. Turn the camshaft timing gear assembly's intermediate shaft index slot in the counterclockwise direction by hand, and set it to the maximum retard angle position.

   HINT:

   • When the cam of the camshaft lifts the valve, the intermediate shaft becomes difficult to turn.
   • The position where the intermediate shaft stops is the maximum retard angle.

2. Install a new O-ring to the timing chain cover.
3. Align the joint of the camshaft timing control motor and the keyway of the camshaft timing gear assembly, and install the motor with the 3 bolts.

   Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf) 

   NOTE:

   • Check that [L] is printed on the label of the camshaft timing control motor.
   • Do not allow foreign matter to contact the oil seal face of the camshaft timing control motor (connecting surface with timing chain cover sub-assembly).
   • When installing the camshaft timing control motor, do not use excessive force.
   • Align the timing chain cover sub-assembly knock pin with the camshaft timing control motor pin hole to install the camshaft timing control motor.
   • Install the camshaft timing control motor with the arrow facing upward, as shown in Fig 2.
   • Do not drop the camshaft timing control motor. If dropped, replace it.
   • Do not disassemble the camshaft timing control motor assembly. If disassembled, replace it.

HINT:

Disconnect the cable from the from the negative (-) battery terminal so that the maximum retard angle of the camshaft timing control motor assembly will be learned.

1. Perform initialization (see INITIALIZATION ).
   NOTE: Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.
