Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical issues during repair.
Ensure the engine is cool before starting work.

2. Oil Change and Filter Replacement

Sub-steps:
1. Drain the engine oil using a wrench and oil drain pan.
2. Replace the oil filter with a new one.
3. Refill the engine with the manufacturer-recommended oil type (typically 5W-30).
Tools Required: Oil drain pan, wrench, oil filter wrench, funnel.

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 with a socket set and take out the solenoid.
4. Install the new VVT solenoid and secure it with bolts.
5. Reconnect the electrical connector.
Tools Required: Socket set, ratchet, torque wrench.

4. Inspect and Adjust Timing Chain/Belt

Sub-steps:
1. Remove the engine cover to access the timing chain/belt.
2. Align the timing marks on the crankshaft and camshaft according to the service manual.
3. If misaligned, adjust the tensioner or replace the timing chain/belt if worn.
Tools Required: Torque wrench, timing tool set.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear the P0011 code from the ECU.
