Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before starting work.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Drain the old engine oil using an oil pan and replace the oil filter with a new one.
3. Refill with the manufacturer-recommended oil type (typically 0W-20 for Toyota Tacoma).
Tools Required: Oil wrench, oil pan, socket set, funnel.

3. Inspect and Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid (usually near the top of the engine).
2. Disconnect the electrical connector and remove bolts securing the solenoid.
3. Replace with a new VVT solenoid and secure it with bolts.
4. Reconnect the electrical connector.
Tools Required: Socket set, torque wrench.

4. Check and Adjust Timing Chain/Belt

Sub-steps:
1. Remove necessary components to access the timing chain/belt (e.g., engine cover, water pump, etc.).
2. Inspect the timing marks and ensure they align correctly according to the service manual.
3. Adjust the tensioner if necessary and replace any worn components.
Tools Required: Timing tool set, torque wrench, socket set.

5. Clear Codes and Test

Sub-steps:
1. Reconnect the battery terminal.
