Sub-steps:
1. Drain the old engine oil by removing the oil drain plug.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically 30 ft-lbs).
4. Fill the engine with the required oil type (5W-20 or specified by the manufacturer).

3. Inspect or Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually near the camshaft).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts and take out the solenoid.
4. Inspect for oil leaks or damage; replace if necessary.
5. Reinstall or replace with a new solenoid and torque bolts to specifications.

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt cover.
2. Inspect the timing marks to ensure proper alignment.
3. If misaligned, follow the manufacturer’s procedure to adjust or replace the timing chain/belt.

5. Clear Codes and Test Drive

Sub-steps:
1. Reconnect the battery.
2. Use an OBD-II scanner to clear the P0011 code.
3. Start the engine and monitor for any abnormal noises.
