Safety Warnings: Ensure the engine is cool and use gloves to avoid oil burns.

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually near the camshaft).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts and take out the old solenoid.
4. Install the new VVT solenoid and tighten the bolts to the manufacturer's torque specifications (typically around 10-12 ft-lbs).
5. Reconnect the electrical connector.
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the battery is disconnected before handling electrical components.

4. Clear Codes and Test Drive

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear the P0011 code.
3. Start the engine and allow it to reach operating temperature.
4. Take the vehicle for a test drive to confirm the code does not return.
Tools Required: OBD-II scanner.
