Hey guys, theres a pump of some sort kinda below my air intake/filter. Next to the wiper fluid reservoir. I was working on my stereo this weekend, and every 10 mins or so, it would start up and make a grrrrr sound and shut off. what the heck is it?? what does it do??

Thanks!

sounds like an elc pump, which airs up the back shocks. you happen to have an inflater in the back too?

leaking strut.

It'* neither. That'* the PMV assembly for the ABS and Traction control doing a self-test on the pump. It uses pressurized brake fluid for traction control.

could be that too, it depends on how long the noise was on though. and if it was a motor grr or just a mild grrr

BELOW the intake/Filter. Not behind.

yeap jeff thats the pmv i know that

I have no idea what your issue is. However, this is SOOOO ironic!!

That'* exactly what my 94 88 Royale is nicknamed too! LOL. And for that exact damn reason!!!

Vital, that is awesome!! Geniuses think alike i guess...


It turns out it is the automatic leveling pump- is that the PMV? I noticed it so much, cause i was in and out of the trunk so much workin on stereo stuff... My boss said its prolly pretty expensive if it goes bad and has to be replaced...

Thanks guys!

I thought you said it was BELOW the airbox? The ELC (leveler) pump is between the airbox and the strut tower.
