PINPOINT TEST HM: Secondary Air Injection (AIR) System: Introduction

2012 Volkswagen Beetle Base, 2.5L Eng VIN P, Standard TransSECTION Introduction
WARNING: This page does not describe the selected car, but rather 35 other vehicles, including the 2007 Mercury Mountaineer, 2007 Mercury Monterey, 2007 Mercury Montego, 2007 Mercury Milan, and 2007 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.

This pinpoint test is intended to diagnose the following:

  • secondary air injection system relay (14B192)
  • electric air injection pump (9A486)
  • secondary air injection bypass solenoid (9H465)
  • harness circuits: B+, VPWR, AIR, AIRM, ground
  • powertrain control module (PCM) (12A650)
  • secondary air injection diverter valve (9F491)
  • vacuum supply
  • hoses
  • partial restricted exhaust

Refer to the appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
