Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Drain the old engine oil using a wrench to remove the oil drain plug.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and refill the engine with the correct type and amount of oil (consult the owner’s manual for specifications).

3. Inspect VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually found near the top of the engine).
2. Disconnect the electrical connector.
3. Remove the solenoid using a socket set and inspect it for any signs of damage.
4. Clean the solenoid and replace it if necessary.

4. Inspect Timing Chain/Belt

Sub-steps:
1. Remove the engine cover if applicable.
2. Check the alignment of the timing marks on the timing chain/belt.
3. Ensure the tensioner is functioning properly; replace if it is worn or broken.
4. Reassemble any components removed during inspection.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the battery terminals.
2. Use an OBD-II scanner to clear the P0011 code from the ECU.
3. Start the engine and allow it to idle to check for any additional issues.
