Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, basic socket set, torque wrench, engine oil (if needed).
• Safety Warnings: Disconnect the battery before working on electrical systems.

2. Change Engine Oil (if necessary)

• Sub-steps:
  • Drain the old engine oil using a wrench to remove the oil drain plug.
  • Replace the oil filter using an oil filter wrench.
  • Reinstall the drain plug and tighten to the manufacturer's specified torque (usually around 25 Nm).

3. Replace VVT Solenoid (if faulty)

• Sub-steps:
  • Locate the VVT solenoid, typically found on the engine's valve cover.
  • Disconnect the electrical connector from the solenoid.
  • Remove the mounting bolts using a socket set.
  • Carefully pull the solenoid out of its housing.
  • Install the new solenoid and secure it with the mounting bolts (torque to manufacturer specifications).
  • Reconnect the electrical connector.

4. Timing Chain/Belt Inspection

• Sub-steps:
  • Remove any components obstructing access to the timing cover (e.g., belts, pulleys).
  • Inspect the timing chain or belt for wear, slack, or damage.
  • If necessary, replace the timing chain/belt according to manufacturer specifications.
