Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before working.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain the old engine oil using an oil drain pan.
2. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated.
3. Refill the engine with the recommended oil type (typically 5W-20 or as specified in the owner’s manual).
4. Start the engine and let it run for a few minutes, then check for leaks.

3. Replace VVT Solenoid

Tools Required:
- Socket set
- Torque wrench
Sub-steps:
1. Locate the VVT solenoid, usually near the camshaft cover.
2. Disconnect the electrical connector from the solenoid.
3. Unbolt the solenoid and remove it from the engine.
4. Install the new VVT solenoid and torque the bolts to manufacturer specifications (typically around 89 in-lbs).
5. Reconnect the electrical connector.

4. Inspect Timing Chain/Belt and Camshaft Position Sensor

Sub-steps:
1. Remove any necessary components to access the timing chain/belt.
2. Check for proper alignment and signs of wear or damage.
3. If necessary, replace the timing chain/belt following manufacturer specifications.
4. Inspect the camshaft position sensor; replace if damaged.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the codes and reset the check engine light.
