Pump Type: The Air Pump, or Air Injector Reactor (AIR), system design is commonly referred to as the smog pump. The smog pump is responsible for supplying fresh, pressurized oxygen into the exhaust stream near the exhaust manifold .
What happens when air pump goes bad?
Engine is running rough
When a smog pump fails the finely tuned air-fuel ratios can be upset, and it will negatively affect the performance of the engine. The engine may have trouble idling, and may drop in engine speed, or stall when the pedal is pressed.
Can you drive with a bad air pump?
While failing a smog test is a serious enough problem, the real danger from a bad air pump is the possibility that reduced engine performance and driveability could cause be hazardous to your driving safety.
What does a bad air pump sound like?
A bad air pump can make a howling noise . ... You should hear a faint vacuum-cleaner sound for about 30 seconds as your air pump operates. The lack of this noise can indicate that the pump is not working.
How do I know if my secondary air pump is bad?
- 1) Check Engine Light.
- 2) Failed Emissions Test.
- 3) Weak Acceleration.
- 4) Engine Stalling.
- 5) Low Idle.
How much does it cost to replace an air pump?
The average cost for an Air Pump Replacement is between $457 and $555 but can vary from car to car.
Do you need a secondary air pump?
As the air pump burns as much fuel as it can, these stunts the emission from the being released to the environment. This alone saves our planet and its atmosphere from damage. Also, if your country or state has an emission testing as a requirement, a secondary air pump is mandatory .

Can I drive without secondary air injection?
You will be fine driving to work in the morning . You will get or already have a CEL for hose being disconnected. The pump only runs for a minute or so on cold start to help burn exhaust gases and heat up the O2 sensor. The reason for the brown color is most likely due to rust from condensation in the pump.
What does the air pump relay do?
The relay controls high current to the AIR pump integral bypass valve , allowing the PCM driver to control low current used by the relay. When the PCM commands ON, voltage should be near 0v.
How do you test a smog pump?
You just take the outlet hose off the rail and check if it is pumping air . If the pump is off the truck, you just spin the pulley and see if air comes out the outlet.
What causes secondary air injection malfunction?
A faulty pump is generally the most frequent cause of the system failing. ... Faulty ground and voltage supply can also cause the pump to fail. Blocked or leaking lines can also cause the failure or malfunction of the control or combination valve, resulting in the failure of the secondary air system.
How do you fix a secondary air system?
