What it means

The secondary air system blows air into the exhaust on a cold start so the catalytic converter warms up faster. The computer found too little air or a fault in the pump or valve control.

This is a make-specific code (GM). The exact meaning can vary by model and year.

What you may notice

  • Engine light on
  • Unusual pump noise on a cold start
  • Usually no change in driving

What could be wrong

  1. 1Air pump seized by moisture or burnt out · Secondary air pump or valve replacement €200–400
  2. 2Check valve stuck · Valve or actuator replacement €120–240
  3. 3Hose loose or cracked · Leak check and hose or gasket replacement €60–120
  4. 4Pump relay or fuse · Fuse replacement and cause check €30–60

Repair difficulty: Moderate

What you can check yourself

On a cold start, listen for the pump droning in the engine bay for a few seconds. You can check the simple things yourself, but the repair is best done in a workshop.

How we fix it

  1. We check pump and valve operation with the diagnostic tool
  2. We check the hoses and relay
  3. We replace the pump or valve
