Tools Required: Oil filter wrench, socket set, oil catch pan.

3. Inspect and Replace VVT Solenoid

Sub-steps:
- Remove the engine cover (if applicable) using a socket set.
- Locate the VVT solenoid and disconnect its electrical connector.
- Remove the solenoid from the engine by unscrewing the mounting bolts.
- Install the new VVT solenoid and reconnect the electrical connector.
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the engine is cool to prevent burns.

4. Verify Camshaft Timing

Sub-steps:
- Remove the timing cover as per the service manual instructions.
- Align the timing marks on the crankshaft and camshaft gears.
- If misaligned, adjust the timing chain/belt as necessary.
- Reinstall the timing cover and torque to specifications.
Tools Required: Torque wrench, timing alignment tools (if necessary).
Safety Warnings: Disconnect the battery before starting work on electrical components.

5. Reassemble and Test

Sub-steps:
- Reinstall any components removed during the process.
