1. Check that the joint of the camshaft timing control with EDU motor rotates smoothly when rotating it by hand.
  OK
  
  Rotates smoothly.
  
  HINT:
  
  Due to the magnetic forces inside the camshaft timing control with EDU motor, the joint may feel as if it is sticking when turning it.
  NOTE:
  - Do not drop the camshaft timing control with EDU motor. If dropped, replace the camshaft timing control with EDU motor assembly.
  - Do not disassemble the camshaft timing control with EDU motor. If disassembled, replace the camshaft timing control with EDU motor assembly.
  - Do not allow foreign matter to contact the oil seal face of the camshaft timing control with EDU motor (connecting surface with timing chain cover).
  If not as specified, replace the camshaft timing control with EDU motor assembly.
2. Inspect the joint clearance.

  1. Using a vernier caliper, measure the joint width.
    Standard width
    
    5.90 to 5.95 mm (0.232 to 0.234 in.)
  2. Using a caliper gauge, measure the keyway part width of the camshaft timing gear assembly.
    Standard width
    
    6.02 to 6.11 mm (0.237 to 0.241 in.)
  3. Subtract the joint width measurement from the keyway part width measurement.
    Standard joint clearance
    
    0.07 to 0.21 mm (0.00276 to 0.00827 in.)
    
    Maximum joint clearance
    
    0.7 mm (0.0276 in.) or more
    
    If the clearance is more than the maximum, replace the camshaft timing control with EDU motor assembly or camshaft timing gear assembly.
