Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, VVT solenoid wrench, multimeter.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery cable to prevent electrical shorts.

2. Change Engine Oil and Filter

• Drain the old engine oil by removing the oil drain plug.
• Replace the oil filter with a new one.
• Refill the engine with the manufacturer-recommended oil type.
• Safety Warning: Allow the engine to cool before working on the oil system.

3. Inspect and Replace VVT Solenoid

• Locate the VVT solenoid on the engine (usually near the camshaft).
• Disconnect the electrical connector and remove the mounting bolts.
• Install the new VVT solenoid and reconnect the electrical connector.
• Torque Specification: Refer to the vehicle service manual for proper torque values.

4. Check Timing Chain/Belt

• Remove any necessary covers to access the timing chain/belt.
• Inspect the timing chain/belt tensioner and guides for wear.
• If worn, replace the tensioner, guides, and chain/belt as needed.
• Ensure all timing marks align correctly during reassembly.

5. Clear Codes and Test

• Reconnect the negative battery cable.
• Use an OBD-II scanner to clear the P0011 code.
• Start the engine and allow it to reach operating temperature to ensure normal VVT operation.
