Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, oil catch pan, and basic hand tools.
Ensure the vehicle is on a level surface and the engine is cool. Disconnect the battery.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the drain plug and allow the old oil to fully drain.
3. Replace the oil filter using an oil filter wrench.
4. Install a new drain plug and torque it to the manufacturer's specifications (typically 25-30 Nm).
5. Refill with the recommended engine oil type and quantity (consult owner's manual).

3. Inspect and Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually near the engine's timing cover).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts with a socket set (torque specifications vary).
4. Replace the solenoid with a new part, ensuring proper alignment.
5. Reattach the electrical connector.

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt cover.
2. Inspect the chain/belt for wear, slack, or misalignment.
3. If necessary, replace the timing chain/belt as per manufacturer specifications.
4. Reassemble components in the reverse order of removal.

5. Clear Codes and Test

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any stored trouble codes.
3. Start the engine and let it idle for a few minutes.
4. Check for any reoccurring codes or symptoms.
