Hi all

There is some black electric pump which is positioned between the radiator and the engine, and has lines going to something above the exhaust manifold. This pump will continue to go on and off when the car is off, and will drain the battery. Any idea what is this pump for, and what might be the problem?

That is your air pump for the emission. unplug the connector and your draw should stop. Then replace the pump. Because it will effect the engine. And the check engine lamp will go on.

 

I found that the relay is getting stuck and causing this pump to continue running when the car is off.
I couldn't find a replacement part for this relay. Any idea how can I find it?
Why would this effect the engine performance? Can I drive with this pump disconnected?
