The Secondary airpump on mine is located under the front passenger side infront of the wheel, and it supposedly it has something to do with the catalytic converter(s) cant say for sure.

Someone will be able to comfirm

HTH

 

The purpose of the secondary air injection system is to decrease exhaust gas emmisions when the engine is cold.The system achieves this by raising the temp of the exhaust gases which has the effect of quickly warming the catalytic convertor up to its normal operating tempreture. Once the cat convertor is up to temp the air injection system then switches off.

And like nixoro says it is on the passenger side next to the wheel ,, Looks like a pump with pipes coming from it

 

Thanks, but how does it raise the temp?

The system consists of a pump, the air cut-off valve and the solenoid valve and is controlled by the ecu. When the engine is cold , the engine solenoid valve switches the air valve to open and the pump injects a controlled amount of air into the cylinder head exhaust ports.The air then mixes with the exhaust gases , Causing any unburned particles of the fuel in the mixture to be burnt in the exhaust manifold which effecttively raises the tempreture of the exhaust gasses. Once the catalytic convertor is up to tempreture the solenoid valve closes the air valve and the pump is switched off. A non-return valve prevents the exhaust gasses passing through the air valve.

 

Thanks for that Mark

 

Yeah CHEEEEEEEERS DANUK!!!!!!!!!!!!!!!!!!! DONT MENTION IT

 

Yeah CHEEEEEEEERS DANUK!!!!!!!!!!!!!!!!!!!

you too
