Replace the VVT (Variable Valve Timing) solenoid on the intake camshaft to restore proper valve timing control and resolve check engine lights or performance issues.

Warnings

Tools required

Parts

• VVT solenoid (intake camshaft) × 1 — 15330-0V010 or equivalent OEM
• VVT solenoid O-ring seal × 1 — Usually included with solenoid

Preparation

1. Park vehicle on level surface and engage parking brake.
2. Allow engine to cool completely.
3. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge.
4. Remove engine cover by pulling upward on the cover - it is retained by clips.
5. Have a clean workspace ready to inspect old solenoid and avoid contamination.

Procedure

1. 1

   Locate the VVT solenoid
   The VVT solenoid is mounted on the front-left side of the cylinder head near the timing chain cover. It has a single electrical connector and one mounting bolt. Face the engine from the front - it is on the driver's side of the engine.
2. 2

   Disconnect electrical connector
   Press the tab on the electrical connector and pull straight out to disconnect it from the VVT solenoid. Do not pull on the wires. If the connector is stuck, gently wiggle it side to side while pulling.
3. 3

   Remove VVT solenoid mounting bolt
   Using a 10mm socket, remove the single bolt securing the VVT solenoid to the cylinder head. Place the bolt in a parts tray to avoid losing it.

4. 4

   Extract the VVT solenoid
   Grasp the solenoid body firmly and pull straight out from the cylinder head. It may require a slight twisting motion to break the O-ring seal. Do not pry against the cylinder head as this may damage the sealing surface.
5. 5

   Inspect the mounting bore
   Use a clean shop towel to carefully wipe the solenoid mounting bore in the cylinder head. Look for any debris, metal shavings, or old O-ring material. The bore must be completely clean. Check for oil passages - they should be clear of sludge.
6. 6

   Inspect old solenoid and O-ring
   Examine the old solenoid O-ring for damage, cracks, or flattening. Check the solenoid screen filter (if visible) for debris or sludge buildup - excessive contamination indicates poor oil maintenance. Note condition for diagnosis.
7. 7

   Prepare new VVT solenoid
   Remove new solenoid from packaging. Verify it matches the old unit in connector type and mounting configuration. Check that the O-ring is properly seated in the groove on the solenoid body. Apply a thin film of clean engine oil to the O-ring to aid installation.
8. 8

   Install new VVT solenoid
   Align the solenoid with the mounting bore and press it firmly into place by hand until it seats completely against the cylinder head. Ensure the O-ring does not roll or pinch during installation. The solenoid should sit flush - do not force it.
9. 9

   Install and torque mounting bolt
   Thread the mounting bolt by hand to ensure proper threading. Using a torque wrench, tighten the bolt to 10 Nm (7 lb-ft). Do not overtighten as this can crack the solenoid housing.

10. 10

    Reconnect electrical connector
    Push the electrical connector onto the VVT solenoid until it clicks into place. Verify it is fully seated by gently tugging on the connector body (not the wires). The connector should be secure.
11. 11

    Reinstall engine cover
    Align the engine cover with the mounting clips and press down firmly until all clips engage. Ensure the cover is seated evenly around its perimeter.
12. 12

    Reconnect battery and clear codes
    Reconnect the negative battery terminal. Start the engine and verify the check engine light follows its normal self-test pattern. Use an OBD-II scanner to clear any stored VVT-related codes (P0010, P0011, P0012, P0017, etc.).

Reassembly

1. Ensure all electrical connections are secure and properly routed away from hot exhaust components.
2. Verify engine cover clips are fully engaged and cover sits flat.
3. Double-check that no tools or shop towels were left in the engine bay.

Verification

• Start the engine and listen for normal operation - there should be no rattling or unusual valve train noise.
• Let the engine idle for 2-3 minutes and verify the check engine light does not return.
• Rev the engine gently to 2000-3000 RPM and confirm smooth operation without hesitation.
• Take a short test drive and verify normal acceleration and engine response, particularly during light throttle conditions.
• After test drive, re-scan for codes to confirm no VVT-related faults have returned.
• Inspect the solenoid area for any signs of oil leakage around the O-ring seal.
