What to know about the Air Pump:
Years ago, exhaust systems were pretty simple. The spent gases expelled from the engine through the exhaust manifold, into the exhaust pipe, and then out via a muffler. However, stricter environmental laws and regulations have considerably impacted today’s automotive exhaust systems. A number of new parts, including your car’s air pump, must be in place to make sure that the engine emits as few harmful elements as possible. Also known as the smog pump, this secondary air injection system basically pushes air into the exhaust system to help ensure that all unburned fuel is combusted. If the air pump is not functioning, excess emissions and pollutants will be released into the atmosphere.

Facts to Note:
Your air pump is electronic, and subject to a number of potential problems, including issues with wiring or shorts.
Your air pump is an important part of your emissions system and should not be removed (removing smog pumps is popular with “modders” looking to lighten their vehicle).
You need an operational smog pump to pass your emissions test.
How to Fix:
The vehicle hood is raised and supported
The faulty air pump is removed
The new air pump is fixed
The air pump is tested for proper operation
The vehicle hood is closed and road tested for proper operation
Your car’s air pump is an essential part of your emissions system and helps reduce pollution from your engine. While there is no set life expectancy for these parts, they do fail from time to time. If you suspect there’s a problem with your emissions system, or you’ve failed your emissions test, have your car analyzed by one of your expert mechanics.

Common symptoms indicating you may need to change the Air Pump:
Engine runs rough (due to insufficient pressure)
Check Engine light is on
Car experiences reduced power while accelerating
Importance of this service:
Having an operational emissions system is vital for many reasons; including reducing pollution and ensuring that your engine runs properly. Without an operating air pump the pressure in your exhaust will be too low, the engine will run poorly, and fuel efficiency will reduce. Have a faulty air pump changed quickly.
