how to fix P0011 timing over-advanced code in Toyota Tacoma N300 (2016-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to prevent electrical shorts.
• Raise the vehicle and secure it with jack stands if necessary.

2. Check and Change Engine Oil

• Sub-steps:
  1. Remove the oil drain plug and drain the old oil into a suitable container.
  2. Replace the oil filter with a new one.
  3. Reinstall the oil drain plug and tighten it to the manufacturer's torque specification (typically around 30 ft-lbs).
  4. Add new engine oil that meets Toyota specifications (usually 0W-20 or 5W-20).

3. Inspect and Replace VVT Solenoid

• Sub-steps:
  1. Locate the VVT solenoid, typically found on the engine’s cylinder head.
  2. Disconnect the electrical connector from the solenoid.
  3. Remove the mounting bolts securing the solenoid and carefully take it out.
  4. Install the new VVT solenoid by reversing the removal steps and torque the bolts to the specified value (usually around 89 in-lbs).
  5. Reconnect the electrical connector.

4. Check Timing Chain/Belt

• Sub-steps:
  1. Remove any components obstructing access to the timing chain cover, such as the front engine cover, if required.
  2. Inspect the timing chain/belt for signs of wear, stretching, or damage.
  3. If necessary, replace the timing chain/belt, following specific torque settings for any tensioners or guides per the manufacturer's specifications.
  4. Reinstall all components removed during inspection.

5. Clear Codes and Test Drive

• Sub-steps:
  1. Reconnect the negative battery terminal.
  2. Use the OBD-II scanner to clear the P0011 code.
  3. Start the engine and monitor for any abnormal noises or performance issues.
  4. Take the vehicle for a test drive to verify that the issue is resolved and that the check engine light does not reappear.
