Solution

1. Preparation

Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.
Gather necessary tools and parts.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench.
3. Install the drain plug and tighten to the manufacturer's torque specification (typically 20-25 ft-lbs).
4. Refill the engine with the correct grade of oil (typically 5W-20) as per the owner's manual.

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually found on the cylinder head).
2. Disconnect the electrical connector from the VVT solenoid.
3. Remove the mounting bolts securing the solenoid using a socket set.
4. Replace the old solenoid with the new one, ensuring the gasket is in place.
5. Torque the mounting bolts to the manufacturer's specifications (typically 89 in-lbs).

4. Reset Engine Control Module

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use an OBD-II scanner to clear the codes from the ECM.
3. Start the engine and allow it to reach operating temperature.
