Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Change Engine Oil and Filter

Sub-steps:
- Place a drain pan under the oil pan.
- Remove the oil drain plug and allow the oil to fully drain.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug with the specified torque (usually around 30 ft-lbs).
- Refill the engine with new oil that meets Toyota specifications (typically 0W-20 or 5W-30).

3. Inspect and Replace VVT Solenoid

Sub-steps:
- Locate the VVT solenoid (usually near the engine’s valve cover).
- Disconnect the electrical connector and remove the mounting bolts.
- Inspect the solenoid for oil leaks or damage.
- Replace with a new VVT solenoid if necessary, ensuring to use the correct part number.

4. Check Timing Chain/Belt

Sub-steps:
- Remove any components obstructing access to the timing cover (such as the engine cover).
- Carefully inspect the timing chain/belt for any signs of wear or misalignment.
- If the timing is misaligned, realign according to the manufacturer’s specifications, using a timing tool if necessary.

5. Reconnect Battery and Clear Codes

Sub-steps:
- Reconnect the negative battery terminal.
- Use the OBD-II scanner to clear the P0011 code from the vehicle’s computer.
