The AIR pump (Air Injection System Pump) or smog pump in your motor vehicle is a critical part of the emission reduction system. This A.I.R. pump is designed to pump in clean air and combine it with your engine's hot exhaust gas as it leaves the combustion chambers. The air injection pump is a critical piece of equipment that needs to be working properly in order to maintain proper emissions readings. The reason for the AIR pump system is because the hot exhaust gas by itself is not enough to complete the burning of the exhausted gas mixture. When the air pump system is working properly, it will allow the continued burning of the fuel mixture as it travels down the exhaust system and eventually out the tailpipe.

There are basically two ways how the actual air pump motor itself is powered.

  • (1) Mechanical via a drive belt system
  • (2) DC power via electric motor (sometimes used as secondary pumps)
1A currently is carrying the electrically DC powered AIR pump motors. These electric air pump motors are built to strict quality control standards and come with a limited lifetime warranty.

Symptoms of an electric AIR pump malfunction:

  • Poor Idle
  • Service Engine Soon (SES) light illuminates
  • Trouble code from a computer scan displays code P0410
  • Increased Oxides of Nitrogen NOx emissions
  • Corroded electric motor
  • Failed vehicle emission test
  • Frozen motor
It is possible to diagnose some AIR pump problems. Consult your vehicle's repair manual and follow all precautions when performing any type of diagnosis. Operating your vehicle on a public road with disabled emission equipment could violate the law.

Our AIR pump motors are made to the same specifications as the originals. They will fit and function with no hassle. They come with everything needed to change out the old motor.

Whether your car or truck needs a new electric AIR pump or you are performing preventative maintenance, purchase a new AIR pump motor from 1A Auto today.

Remember that a properly working AIR pump assembly results in both increased gas mileage and reduced Oxides of Nitrogen (NOx) emissions.
