3. If low, add the recommended oil type (0W-20 or as specified in the owner's manual).
4. If dirty, consider an oil change.
Tools Required: Oil dipstick, funnel for adding oil.

3. Inspect and Replace VVT Solenoid

Sub-steps:
1. Disconnect the negative battery terminal.
2. Locate the VVT solenoid (usually found on the engine head).
3. Unplug the electrical connector and remove the mounting bolts.
4. Replace the solenoid with a new one.
5. Reattach the electrical connector and mount bolts securely.
Tools Required: Socket set, ratchet, torque wrench (if specified).

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any obstructing components to access the timing cover.
2. Inspect the timing chain/belt for wear or looseness.
3. If worn, replace the timing chain/belt according to the manufacturer’s specifications.
Tools Required: Socket set, timing tool kit (if necessary).

5. Test VVT Operation

Sub-steps:
1. Reconnect the battery terminal.
2. Start the engine and allow it to reach operating temperature.
3. Use an OBD-II scanner to monitor camshaft timing and verify if the P0011 code returns.
Tools Required: OBD-II scanner.
