Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Gather tools and necessary replacement parts.
• Disconnect the battery to avoid electrical shorts.

2. Change Engine Oil and Filter

• Sub-steps:
  1. Raise the vehicle with a jack and secure it with jack stands.
  2. Drain the engine oil by removing the oil drain plug and allow it to fully drain.
  3. Replace the oil filter using an oil filter wrench.
  4. Install the drain plug with the appropriate torque (typically 25-30 ft-lbs).
  5. Fill the engine with the manufacturer-recommended oil (typically 0W-20 for Toyota).

3. Inspect and Replace VVT Solenoid

• Sub-steps:
  1. Locate the VVT solenoid on the engine (usually near the camshaft).
  2. Disconnect the electrical connector from the solenoid.
  3. Remove the mounting bolts using a socket set.
  4. Replace the solenoid with a new one, ensuring proper orientation.
  5. Reconnect the electrical connector.

4. Check Timing Chain/Belt

• Sub-steps:
  1. Remove the engine cover to access the timing chain/belt.
  2. Inspect the timing marks to ensure they align correctly.
  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 the OBD-II scanner to clear the P0011 code.
  3. Conduct a test drive to monitor engine performance.
