• Tools Required: Socket set, ratchet, torque wrench, multimeter
• Locate the VVT solenoid (usually found on the engine's cylinder head).
• Remove the electrical connector from the solenoid.
• Unbolt the solenoid from its mounting (typically 10mm bolts).
• Inspect the solenoid for damage; replace it if necessary.
• Reinstall the new solenoid and tighten bolts to the manufacturer’s torque specifications (usually around 8-10 ft-lbs).

• Reinstall the drain plug and tighten to the manufacturer’s specifications (typically around 20-30 ft-lbs).
• Fill the engine with the manufacturer-recommended oil type (usually 0W-20 for Toyota).

4. Check Timing Chain/Belt

• Tools Required: Socket set, torque wrench
• Remove the engine cover if necessary to access the timing chain/belt.
• Inspect for wear, tension, and proper alignment.
• If damaged, follow manufacturer instructions for timing chain/belt replacement, ensuring proper alignment marks are used during installation.

5. Clear Codes and Test Drive
