Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Change Engine Oil

Sub-steps:
1. Locate the oil drain plug and place a drain pan underneath.
2. Remove the drain plug and allow the old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and tighten it to the manufacturer's torque specification (typically around 25-30 ft-lbs).
5. Fill the engine with fresh oil according to the manufacturer’s specifications (usually 5W-30 or 0W-20).

3. Replace VVT Solenoid

Tools Required: Socket set, torque wrench, gasket scraper
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 and carefully take out the solenoid.
4. Clean the mounting surface on the engine to ensure a proper seal.
5. Install the new VVT solenoid and torque the bolts to the manufacturer’s specifications (usually around 89 in-lbs).

4. Clear Codes and Reassemble

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear the check engine light codes.
3. Start the engine and allow it to reach operating temperature.
4. Perform a visual inspection for leaks around the solenoid and check for any abnormal noises.
