Does this sound like a steering sensor issue

while driving down the road it seems to act up like the wheels are going to fall off from being loose.

i just replaced the pitman arm and now i dont have any power steering at low engine speeds or when trying to Parallel park. However, If i give it a little gas it works. Does this sound like the steering position speed sensor issue?



is it a faulty pump? i ask this because it makes the noise like when you turn the wheel all the way but if you give it gas it goes away.


Im thinking it might be the sensor under the dash. tell me what you think.

Replaced the pump and everything is working as it should.
