Read This First

This code identifies the failed diagnostic test or circuit family. Confirm the basic checks before replacing parts, and keep freeze-frame data until the repair is verified.

Common Checks

  • Inspect the cylinder 2 spark plug, coil, boot, and injector connector.
  • Swap ignition parts with a neighboring cylinder and rescan.
  • Check injector pulse and compression if the misfire stays on cylinder 2.

Common Repairs

  • Replace the plug, coil, boot, wire, or injector proven faulty by testing.
  • Repair wiring or compression issues when ignition parts are not the cause.
