Power steering pully stops at pump stops

Power steering pully stops at pump stops - January 19, 2016 03:01 pm UTC

We noticed this weekend that the power steering pulley stops and stops all belts when we turn he tires to full lock...

Have a video of it here... https://www.rallysputnik.com/post-pines-damage-assessment/

Wonder if anyone has any ideas? we tightened the belt up more made it better but still happening... I have a spare pump and rebuild kit so I will do that when I get some time...

I think every car experiences some version of this. Generally, any car with power steering when you turn to full lock you hear some sort of complaining from the engine compartment. I can imagine it would be the pump straining to overcome the positive mechanical limit of travel.

Ziggy, I figured that as well was just kinda taken back when all the belts stopped moving...

Bryce has no issue with this when we race and we are not often at lock on the stages... I was more curious if it is normal and/or sign of impending failure...

On 2Gs we have an electrical wire connected to PS that bumps up idle depending on the PS load.

Here is some info from the web

You can remove it yes, n the CEL shouldn't turn on. The only side affect is that the strain the power steering pump puts on the engine will decrease your RPM's and possibly causing your engine to cut out. Nothing bad will happen its there just to sense the pressure of the pump from the wheels turning to tell the ecu to bum up the RPM's a bit to not stall out the engine.

1g has this too but it's just a ground wire and I am really not to sure how effective it is as mine was flopping around for a while before it got fixed

Ours is not connect I know that for a fact... The issue to be seem more like the pressure bypass switch in the pump might be done or some one did a high RPM mod on the wrong spring...

Either way I will rebuild the spare and see what happens...
