VVT Solenoid - Single

Replace the Variable Valve Timing (VVT) solenoid on the 1.5L turbocharged engine to restore proper valve timing control and resolve engine performance or check engine light issues.

Warnings

Tools required

Parts

• VVT solenoid × 1 — 15810-5AA-003 or equivalent OEM
• VVT solenoid O-ring/seal × 1 — Typically included with solenoid

Fluids

• Honda Genuine 0W-20 — 0.25 qt

Preparation

1. Ensure engine is completely cold to the touch
2. Disconnect negative battery terminal and wait 3 minutes
3. Remove engine cover by pulling upward on the front edge clips
4. Place oil drain pan beneath work area to catch any oil drips

Procedure

1. 1

   Locate the VVT solenoid
   Identify the VVT solenoid on the front of the cylinder head, driver's side near the timing chain cover. It has a single electrical connector on top and is secured by one 10mm bolt.
2. 2

   Disconnect electrical connector
   Press down on the locking tab of the electrical connector and pull directly away from the solenoid. Do not pull on the wiring harness. If the connector is stubborn, gently wiggle it while pulling.
3. 3

   Remove VVT solenoid mounting bolt
   Using a 10mm socket and ratchet, remove the single bolt securing the VVT solenoid to the cylinder head. Keep this bolt clean and inspect threads for damage.

4. 4

   Extract VVT solenoid
   Grasp the solenoid body firmly and pull straight out with steady pressure. A small amount of engine oil will drain from the bore. The solenoid may require slight twisting while pulling if the O-ring has seated firmly. Do not rock or bend the solenoid during removal.
   ⚠Approximately 1-2 ounces of engine oil will spill when the solenoid is removed. Position drain pan accordingly.
5. 5

   Clean solenoid bore and inspect
   Using a clean shop towel, wipe the solenoid bore opening in the cylinder head. Inspect for metal debris, sludge, or scoring. The bore should be clean and smooth. If excessive sludge is present, this indicates poor oil change intervals and the engine may require additional service.
   ⚠Do not allow any shop towel fibers or debris to fall into the solenoid bore. Cover the opening if you need to step away.
6. 6

   Prepare new VVT solenoid
   Remove the new VVT solenoid from packaging. Inspect the O-ring seal for damage and ensure it is properly seated in the solenoid groove. Apply a light coating of fresh engine oil to the O-ring to ease installation and prevent tearing.
7. 7

   Install new VVT solenoid
   Align the new solenoid with the bore and insert straight in without twisting. Push firmly until the solenoid mounting flange sits flush against the cylinder head surface. Ensure the electrical connector is oriented toward the wiring harness location.
8. 8

   Install and torque mounting bolt
   Thread the 10mm mounting bolt by hand to ensure proper alignment, then tighten to specification using a torque wrench. Do not overtighten as this can crack the solenoid housing.

9. 9

   Reconnect electrical connector
   Push the electrical connector straight onto the solenoid until you hear and feel a distinct click. Gently tug on the connector to verify it is locked in place. The locking tab should be fully seated.
10. 10

    Check engine oil level
    Remove the oil dipstick and check engine oil level. Add oil if necessary to bring level to the upper mark. The small amount lost during solenoid replacement typically does not require adding oil, but verify before starting engine.

Reassembly

1. Reinstall engine cover by aligning clips and pressing down firmly until all clips engage
2. Reconnect negative battery terminal and tighten securely
3. Wipe up any spilled oil from engine bay surfaces

Verification

• Start the engine and verify it runs smoothly without unusual noises from the timing area
• Allow engine to reach operating temperature and confirm no oil leaks around the VVT solenoid
• If replacing due to a check engine light, use an OBD-II scanner to clear codes and verify they do not return after a test drive
• Test drive the vehicle and confirm smooth acceleration with no hesitation or rough running, especially during light throttle conditions
• Verify engine oil level after test drive and top off if necessary
