Related Repair Advice

  • An air injection system trouble code isn't always triggered by a defective air pump. It can also be triggered by a restricted passage or air pipe, a defective check valve, a defective air pump relay, or a wiring problem.
  • On older vehicles, the air pump is typically belt driven. On newer vehicles, an electric pump is used and only operated when necessary.
