Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, timing light, and a basic mechanic's tool kit.
• Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Change Engine Oil and Filter

• Sub-steps:
  1. Drain the old engine oil using a wrench to remove the oil drain plug (make sure to catch the oil in a pan).
  2. Replace the oil filter using an oil filter wrench.
  3. Reinstall the drain plug and tighten it to the manufacturer’s torque specifications.
  4. Fill the engine with new oil (consult the owner’s manual for the correct type and capacity).

3. Replace VVT Solenoid

• Sub-steps:
  1. Disconnect the negative battery terminal.
  2. Remove the engine cover if applicable.
  3. Locate the VVT solenoid on the engine.
  4. Disconnect the electrical connector from the solenoid.
  5. Remove the mounting bolts and take out the old solenoid.
  6. Install the new solenoid, ensuring it seats properly.
  7. Reconnect the electrical connector and replace the engine cover.

4. Inspect and Adjust Timing

• Sub-steps:
  1. Remove any components obstructing access to the timing chain/belt.
  2. Align the timing marks on the camshaft and crankshaft according to the manufacturer’s specifications.
  3. If misaligned, adjust the timing by repositioning the camshaft or replacing the timing chain/belt as necessary.
  4. Reinstall all removed components and ensure they are secured.

5. Reset the Engine Control Module (ECM)

• Sub-steps:
  1. Reconnect the negative battery terminal.
  2. Use an OBD-II scanner to clear the P0011 code from the ECM.
  3. Start the engine and let it idle for a few minutes to allow the ECM to relearn the engine parameters.
