E-CVVT Cover

WARNING: This page is about a different variant/trim than selected.
  1. Remove the center of the E-CVVT motor plug (A) by breaking it.

    NOTE:
    • Remove after 30 minutes of switching "OFF" the ignition to drain out the oil inside the E-CVVT motor plug.
    • Do not tilt the front of engine (timing chain cover side) downward as residual oil may flow out during E-CVVT motor plug removal.
    • If oil flows out during E-CVVT motor plug removal, wipe off immediately and block the motor shaft inlet with a clean towel.
  2. Clean the E-CVVT motor plug mounting surface (A) with oil cleaner.

    NOTE:
    • If the surface is not cleaned, E-CVVT motor plug may be separated due to diminished separation force from residual oil.
    • When spraying oil cleaner, block around the motor shaft inlet and rotor gap with a clean towel to prevent inflow of oil from flowing into the rotor gap.
  3. When reusing the E-CVVT cover, inspect the below items.
    1. If there is sign of leakage from inside the E-CVVT cover, replace it with a new one.
    2. Check for worn connector brush (A).

      Specification  : Over 5 mm (0.1969 in.)

    3. Check for damaged oil seal (A) and replace any damaged E-CVVT cover with a new one.

    4. After inspecting E-CVVT, if no problem is found, replace the o-ring (A) with a new one.

  4. Install the E-CVVT cover.
    1. Apply engine oil on oil seal lip (A).

      NOTE:
      • When applying oil, keep the connector brush (A) clean from foreign materials.

      NOTE:
      • Correctly mount SST onto the motor shaft.
    3. Slowly push the E-CVVT cover (A) until it is flush with the timing chain cover surface.

      NOTE:
      • Installing the E-CVVT cover without SST may cause oil leakage inside the E-CVVT motor due to damaged or separated E-CVVT oil seal.
    4. Pre-tighten the bolts in the below sequence, and then remove the SST (09243-C2000).

      Tightening torque: 

      1.0 - 2.0 N.m (0.1 - 0.2 kgf.m, 0.7 - 1.4 lb-ft)

      Fig 1: E-CVVT Cover Bolts Tightening Sequence

    5. Tighten the bolts to the specified torque in the sequence below.

      Tightening torque: 

      9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

  5. Install the E-CVVT plug.
    1. By using SST (09243-C2000), insert the plug into the E-CVVT cover hole.

  6. Inspect the pressed depth of E-CVVT plug.
    1. By using a steel ruler, measure the distance from E-CVVT cover center boss to the end of motor shaft ((1)).
    2. By using a steel ruler, measure the distance from E-CVVT cover center boss to the end of E-CVVT plug ((2))

    3. Calculate the pressed depth ((3)) of motor plug.

      If out of specification, reinstall after replacing the E-CVVT plug with a new one.

      Pressed depth  (3)= (2) - (1)

      Specification  - 2.1 mm (0.0433 - 0.0827 in.)

  7. Insert the E-CVVT cover plug so that the protrusion reach to E-CVVT cover groove correctly.

    NOTE:
    • Check how much protrude after installing the E-CVVT plug.

    • Be careful that the plug is not inserted inside E-CVVT cover beyond the regulated range.
  8. Install the engine support bracket (A).

    Tightening torque: 

    39.2 - 44.1 N.m (4.0 - 4.5 kgf.m, 28.9 - 32.5 lb-ft)

    1. Pre-tighten the bolts in the sequence (1→2→3).
    2. Turn the bracket counterclockwise and then tightening the bolt 1.
    3. And then tighten the bolt in the sequence (2→3→4→5→6).

  9. Install the engine mounting bracket.

    (Refer to Engine Mechanical System - "ENGINE MOUNTING ")

  10. Perform the E-CVVT learning value erasing using the diagnosis tool.
    NOTE:
    • After replacing or remounting the E-CVVT assembly, be sure to reset the learned value from the additional feature menu on the diagnostic device.
    • When the learned value for electronic cam position is erased, start learning the cam position while cranking. The engine can start once this is completed.
    • Cranking should be repeated for up to 2-3 times to complete learning.
