Sub-steps:
1. Drain the old engine oil using an oil drain pan.
2. Replace the oil filter with a new one.
3. Refill the engine with the manufacturer-recommended oil (usually 5W-30 or 0W-20).

Tools Required:

Oil drain pan
Socket set
Oil filter wrench

3. Check and Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid; it is usually found near the camshaft on the cylinder head.
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts and carefully pull out the solenoid.
4. Install the new VVT solenoid and secure it with the mounting bolts.
5. Reconnect the electrical connector.

Tools Required:

Socket set
Torque wrench

4. Inspect and Adjust Timing Chain/Belt

Sub-steps:
1. Remove the engine cover to access the timing chain/belt.
2. Check the timing marks on the camshaft and crankshaft to ensure they are aligned.
3. If necessary, adjust the tensioner according to the manufacturer's specifications.
4. Reassemble any components removed during inspection.

Tools Required:

Torque wrench
Timing tool kit (if required)

5. Clear Codes and Reset the System
