Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain Oil: Remove the oil drain plug with a socket set and allow oil to fully drain into a pan.
2. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Install the new filter, lubricating the rubber O-ring with fresh oil.
3. Add New Oil: Replace the drain plug and refill the engine with the manufacturer-recommended oil type and quantity (typically 0W-20 for Camry).

Tools Required:

Socket set
Oil filter wrench
Oil drain pan

3. Replace VVT Oil Control Valve

Sub-steps:
1. Locate the VVT Valve: Find the VVT oil control valve on the engine (usually near the camshaft).
2. Disconnect Electrical Connector: Carefully unplug the electrical connector from the valve.
3. Remove the Valve: Unscrew the mounting bolts using a socket set and remove the valve.
4. Install New Valve: Place the new VVT valve in the same position and secure it with bolts to the specified torque (typically around 10-15 Nm).

Tools Required:

Socket set
Torque wrench

4. Clear Codes and Test Drive

Sub-steps:
1. Reconnect Battery: Reattach the battery terminal.
2. Clear Codes: Use the OBD-II scanner to clear the P0011 code from the ECM.
3. Test Drive: Start the vehicle and take it for a test drive to ensure proper operation and check for any recurrence of the check engine light.
