Product Details

The Airtex 1A3019 is a direct-fit replacement secondary air injection pump check valve engineered to restore proper function to your vehicle's emissions control system. This check valve plays a critical role in the secondary air injection (SAI) system by allowing fresh air to flow from the air pump into the exhaust stream during cold engine startup, while preventing hot exhaust gases from flowing back and damaging the pump or associated components.

Key Features:

  • Direct OE replacement for a precise, hassle-free fit
  • Prevents backflow of exhaust gases into the secondary air injection pump
  • Helps maintain proper emissions system operation and supports passing emissions inspections
  • Manufactured to meet or exceed original equipment specifications
  • Restores correct airflow direction in the secondary air injection circuit
  • Durable construction designed to withstand high exhaust heat and pressure cycles

A failed secondary air injection check valve commonly triggers diagnostic trouble codes (DTCs) related to the AIR system and can cause the check engine light to illuminate. Replacing the Airtex 1A3019 check valve is a cost-effective solution to restore emissions system integrity and ensure your vehicle operates within regulatory standards.
