Solution
1. Preparation
  • Gather necessary tools and parts for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool before starting work.
2. Inspect and Replace the Secondary Air Pump
  • Remove any engine covers or components obstructing access to the secondary air pump.
  • Disconnect the electrical connector from the pump.
  • Remove the mounting bolts securing the pump to the engine.
  • Take out the pump and inspect for debris inside the inlet and outlet. Clean if necessary.
  • If the pump is faulty, replace it with a new part.
  • Reinstall the new pump and secure it with mounting bolts, tightening them to the manufacturer’s specifications (typically around 10-15 Nm).
  • Reconnect the electrical connector.
3. Check and Replace the Air Control Valve
  • Locate the air control valve in the secondary air system.
  • Disconnect the electrical connector and vacuum lines from the valve.
  • Remove the valve from its mounting.
  • Inspect for blockage or damage; clean or replace as needed.
  • Reinstall the valve and reconnect the vacuum lines and electrical connector.
4. Verify System Operation
  • Reconnect the negative battery terminal.
  • Start the engine and let it reach operating temperature.
  • Monitor the secondary air pump operation; it should activate for a brief period during cold starts.
  • Use the OBD-II scanner to check for any remaining codes.
