duno have to see on drive tomorrow let it run for a min but pump def made noise whne gas pushed in and key in on position

 

let me know !

 

was fine all day went over speed bumps came back on, came home turned car off thne to on heard pump turn on, started car only 1 light on.. not sure what it is maybe sensor or fluid level dealership said pump is going slowly

 

any other iuput greatly appreciated'

 

If you hear the whine then it sounds as if its working. that said it needs to be bled.

 

i am assuming there is a hot to somewhere on here and what fluid will i need to use to refil it

 

turned it to on just now and held in gas for 30 seconds about and went from 1 light then all 3, turned car off, just held gas for a few seconds in on pump noise was on and only 1 light now, whne i help it at full throttle pump sounded a little different more high pitched then just at 75%

 

this happend to me when my throttle position sensor went bad

 

tps affected acd?

 

My lights will lit up randomly. This only happens when on the freeway. My car starts to buck and it jolts. Its like someone turning a light switch on and off messing with me. I ride it out then it goes away.

 

they is many different things and combos it could be, the best thing you could do is take it to a mitsubishi dealership, they have a code reader for the acd system(known from experience), they charge like 40$ and they should give you a more reliable answer

 

Sounds like a leak.look under the car and see if u see any leaks.also maybe you fluid is low gl

 

Have you done any searching for this topic? Its been beaten to death, granted no one has found a full on 100% fix as each problem seems to be different or just requires a new pump. Some have faulty sensors (though depending on the sensor it will trigger your ABS light), some have leaks in the system or wires that have worn through. Your first step would be to get off the computer and under your car. Poke around a bit and see if any of the wires to the ACD are loose or damaged, try bleeding the system if you can.

I'm having a similar issue where the lights only go on when its 80+ degrees outside, I'm set to re-bleed the system this weekend.

Beyond all the above advice, researching on your own and to bring it to a fellow member who might know about these things your best bet would be to have the dealership pull the code. From what I read the codes are all stored on the ecu until improved conditions are met. Apparently there's a way to 'trigger' a coded light blink from the ACD ECU however I don't trust that method just yet.

Good luck with your issue, do post up when you find any results.

I've seen double posts... but never as many as you just did... [edit] button is your friend.

I know my ACD is doing something, the pump cycles when I put the car in start mode and hold down the gas pedal, I just haven't had time to bleed it yet.

 

lights were off all day till drive home then came on yet again, pump still turns on in "on " position. it has beebn 80+ in pgh past 3 days and that is when it started happening strikes me strange since bruce988 had same issue, thanks for all the great feedback thus far i will prob go to dealership to pull codes and have a peep under and look at acd itself, i go to work it is about 60 degrees out since i start at 6 am and whne i leave its hot as hell at 3 so that heat factor intrigues me
