Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Check the engine oil level using the dipstick.
2. If low, add the correct type of oil (5W-20 or as specified by the manufacturer).
3. If dirty or degraded, perform an oil change:
  - Drain the oil using a wrench and oil pan.
  - Replace the oil filter using an oil filter wrench.
  - Refill with new engine oil as per the manufacturer's specifications.

3. Replace VVT Solenoid

Tools Required: Socket set, torque wrench, ratchet.
Sub-steps:
1. Locate the VVT solenoid (usually on the engine cylinder head).
2. Disconnect the electrical connector from the solenoid.
3. Remove the securing bolts with a socket set.
4. Carefully pull out the solenoid from its mounting location.
5. Install the new VVT solenoid in reverse order and torque to the manufacturer's specification.

4. Clear Codes and Test Drive

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use an OBD-II scanner to clear the P0011 code.
3. Test drive the vehicle for at least 10-15 minutes to check for the reoccurrence of the check engine light and ensure proper operation.
