1995 Galaxy 2.0l Petrol Power Steering Issues

[leo311981]

hi once again since this wonderful site fixed my last problem in a matter of 48 hours i thought i would tell you about my other problem

might even save me garage fees ha ha ha

 

problem i have is power steering

which i must say works fine especially if the engine is cold but once heats up my steering becomes heavy but still able to turn the wheel

but whilst im turning the steering wheel the engine revs to and 3000 revs and sits there till i stop turning the wheel,

if i turn the steering wheel too far i get a loud screatching noise and engine revs even higher,

I have checked fluid levels which are fine , i did a google search for my problem and got nothing ha ha apart from check for burning smell from fluid which i dont have a burning smell.

 

but looking through this site i see alot of posts about alternator pulley do you think this could be my problem

 

as steering works as it should whilst the engine is cold (on choke) but soon as revs drop to just under 1000revs (once warmed up )this is when my problems start it seems to me that the engine is not going fast enough for the steering if you understand what i mean its kinda hard to explain

 

oh i must also add if i put my foot on the accelerator whislt steering i get no noises no screatching and steering is fine

 

thankyou very much for any advice you can give me

do a search for alternator pulley.then see if the symptoms are the same as yours.

right thought i would update you all about my problem,,, after a google search i found 2 possible things that could cause my power steering issue 1 was tps sensor on throttle body the second was alternator pulley as this operates on a clutch ?????? ..

Well any way i decided the easiest thing to change was the tps sensor on the throttle body so went scrap yard (turned out to be not so easy and straight forward ha ha )

i took the hole throttle body including the tps sensor and fitted today took about an an hour and a half for me to swap throttle bodies but problem still was there (dam)

was not happy ....

this pointed the the other possible problem the alternator clutch pulley and after adding up costs as i cant change this my self (aint got a clue ha ha ) thought just scrap it!!!!

but luckily i decided to start un plugging sensors and trying if it made a difference so i unplugged the maf sensor car did not like that ha ha ha

then i unplugged the one nearest the throttle body on air intake pipe nothing happened was still the same .

then i unplugged what i later found thanks to haynes manual was the mass idle meter and done no revving problems does not go mad when i turn the steering wheel

this has got to be my problem soon as i plug it back in my galaxy goes mad especially when sturning the steering wheel

tps has nothing to do with power steering!!!

 

95 petrol model does not have a clutched alternator

 

The screeching/burning smell is because your power steering belt is slipping. Check its condition and tightness.

i dont have a burning smell !!!!!!!!!! my problem was my galaxy would rev very loudly when steering but would only happen when it was warm and would also take far far too long to return to idle which firstly pointed to the alternator pulley which does have a clutched pulley for the steering issue and needs a spline remover tool to take off

the high revs and the amount of time to return to idle pointed towards the tps sensor

but none of these were the problem it turned out to be the mass idle meter as now i have unplugged it car drives fine no problems at all so it will stay unplugged till i get another idle meter

 

but thankyou very much for your comment and is very much appreciated

Hi leo311981

 

I believe there's a switch in the power steering hydraulic circuit which raises the idle speed a small amount, what you were saying about the throttle position sensor causing revs taking a long time to come back down to idle I had this problem with a cougar, turned out to be the multiplug connector to the TPS one of the pins had pushed back in the plug so was not connecting.

 

As for clutched pulleys they are turning up everywhere now, your alternator may have been replaced with the clutch type.

 

You say you have disconnected the "mass idle meter" I think your referring to the MAF sensor (mass air flow) as unplugging the idle control valve will cause the engine to cut out.

 

If it is the MAF that your changing make sure it's the same type/number as your old unit as they all look similar.

no the maf is on the air intake which goes to the trottle body if i unplug that car runs really bad

the one i have unplugged is a cylinder shape on the right

this is the part i have unplugged >>>> http://www.ebay.co.u...=item2ec1155307

 

 

once i unplugged this part i have no problems at all so my problem must be this part

 

iv been calling it the mass idle meter but is actualy called > AIR BY PASS VALVE IDLE SPEED CONTROL

Have you tried removing and cleaning the valve they usually get gummed up with the valve not seating correctly, as I said normally the engine cuts out if you disconnect it while the engine was idling.

[leo311981]

have tried cleaning it but problem still there yes i agree if i disconnect it while the engine is running it does cut out, but if i switch off the engine and remove positive from battery and then disconnect the plug from it replace battery positive car starts fine (unless cold) and runs great just a lack of power but this should do me till new part arrives

couldnt drive around the way it was as a couple of days ago i was at a junction next to a police car and my car started reving up to 4000 revs and then even higher the looks i got off the old bill ha ha ha ha
