Air Pump

[msprince]

I know the corolla has an air pump, but is it located between the n/s/f wheel arch liner and bumper?

Cheers, i thought so.

I have done away with the standard airbox and air intake tubing.

Has anyone removed the air pump as i can only see it as a drain on power as it is not needed anymore.

Im going to have a play about with it at some point but thought id ask.

What is this air pump for?

It's something to do with emissions but cant tell how it works etc etc.

Im searching the net for answers.

" When the engine is cold, air injected at this point cleans up the extra-rich exhaust and raises the temperature of the exhaust so as to bring the catalytic converter to operating temperature quickly. Once the engine is warm, air is injected to the downstream location — the catalytic converter itself — to assist with catalysis of unburned hydrocarbons and carbon monoxide. "

Not sure if this for the same pump.
