Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, oil catch pan, and engine oil.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Change Engine Oil and Filter

Sub-steps:
1. Place the oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the oil filter using the appropriate filter wrench.
4. Install the drain plug and torque it to the manufacturer’s specification (typically around 25-30 lb-ft).
5. Refill the engine with new oil per manufacturer recommendations (typically 0W-20 for Camry).

3. Replace VVT Solenoid

Sub-steps:
1. Locate the VVT solenoid on the engine (usually near the camshaft).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts using a socket set.
4. Carefully lift out the solenoid and replace it with a new one, ensuring proper alignment.
5. Torque the mounting bolts to manufacturer specifications (consult service manual).
6. Reconnect the electrical connector.

4. Inspect and Replace Timing Chain/Belt (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt (such as the engine cover).
2. Follow the service manual to align timing marks.
3. Remove the timing chain/belt and replace it with a new one, ensuring proper tension.
4. Reassemble any removed components, torquing bolts as specified.
