how to fix P0011 camshaft timing over-advanced in Toyota Highlander Third Generation (2014-2019)

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, oil filter wrench, and engine oil.
• Allow the engine to cool completely before starting work.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

• Sub-steps:
  1. Locate the oil drain plug and place a drain pan underneath.
  2. Remove the drain plug using a socket wrench and let the oil drain completely.
  3. Replace the oil filter using an oil filter wrench. Ensure to lubricate the rubber gasket of the new filter with new oil before installation.
  4. Reinstall the drain plug and tighten to the manufacturer's specified torque (typically around 27 ft-lbs).
  5. Refill the engine with the correct type and amount of engine oil (usually 0W-20 for this model).

3. Inspect and Replace VVT Solenoid

• Sub-steps:
  1. Locate the VVT solenoid (usually near the front of the engine on the cylinder head).
  2. Disconnect the electrical connector from the solenoid.
  3. Remove the mounting bolts using a socket set and take out the solenoid.
  4. Inspect the solenoid for any signs of contamination or failure.
  5. Install a new VVT solenoid, tightening the bolts to the manufacturer's specifications (typically around 7 ft-lbs).
  6. Reconnect the electrical connector.

4. Check Timing Chain/Belt Alignment

• Sub-steps:
  1. Remove any components obstructing access to the timing chain/belt cover (e.g., intake manifold).
  2. Align the timing marks on the camshaft and crankshaft according to the service manual.
  3. If the timing is misaligned, replace the timing chain/belt and tensioner, following the specific service procedures for alignment and tensioning.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0011 code and any other stored codes.
