Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Lift the vehicle and secure it on jack stands if required for access to the engine.

2. Check and Change Engine Oil

• Sub-steps:
  1. Remove the engine oil drain plug and drain the old oil into a suitable container.
  2. Replace the oil filter using an oil filter wrench.
  3. Reinstall the drain plug and torque to the manufacturer’s specification (typically around 25 Nm).
  4. Fill the engine with the correct type and amount of oil (refer to the owner’s manual; usually 5W-30 synthetic).

3. Inspect and Replace VVT Solenoid

• Sub-steps:
  1. Locate the VVT solenoid (usually near the camshaft).
  2. Unplug the electrical connector and remove the mounting bolts with a socket set.
  3. Remove the solenoid and inspect for debris or damage. Clean the mounting area.
  4. Install the new VVT solenoid, ensuring it is seated properly and tighten bolts to the specified torque (usually around 10 Nm).
  5. Reconnect the electrical connector.

4. Check Timing Chain/Belt Alignment

• Sub-steps:
  1. Remove necessary components (such as the engine cover) to access the timing chain/belt.
  2. Rotate the engine to TDC (Top Dead Center) and align timing marks.
  3. If misaligned, adjust or replace the timing chain/belt as necessary, ensuring proper tension and alignment.

5. Clear Codes and Test Drive

• Sub-steps:
  1. Use the OBD-II scanner to clear the P0011 code.
  2. Start the engine and observe for any unusual noises.
  3. Take the vehicle for a test drive to verify if the issue is resolved.
