Solution

1. Preparation

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

2. Change Engine Oil and Filter

• Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
• Remove the oil drain plug with a socket wrench and allow the old oil to drain completely into the catch pan.
• Replace the oil filter using the oil filter wrench.
• Install the drain plug back and torque it to 30 ft-lbs.
• Refill the engine with the manufacturer-recommended oil type and quantity (typically 0W-20 for Highlander).

3. Replace VVT Solenoid

• Tools Required: Socket set, torque wrench, pliers.
• Locate the VVT solenoid (usually near the engine's timing cover).
• Disconnect the electrical connector from the solenoid.
• Remove the mounting bolts using a socket wrench and carefully take out the solenoid.
• Install the new VVT solenoid, securing it with the mounting bolts to the manufacturer's specified torque (typically 7-9 ft-lbs).
• Reconnect the electrical connector.

4. Inspect and Adjust Timing Chain/Belt

• Tools Required: Timing tool set, torque wrench.
• Remove the necessary components to access the timing chain/belt (may include covers and accessories).
• Inspect the timing chain/belt for wear, slippage, or misalignment.
• If necessary, adjust or replace the timing chain/belt as per the manufacturer's specifications.
• Ensure correct alignment using timing tools before reassembling.

5. Reconnect Battery and Clear Codes
