Strange steering wheel behavior
Hi all,
Maybe somebody can explain this behavior.
I've noticed some strange behavior on my 07 TSX ( 350 miles on it). On slow speed or during braking (close to the stop) steering wheel became more heavier and trying to turn left or right a little bit. Not that I can't control it but it noticeable. Funny thing that it not happens all time, but pretty often.
There is no problem on highway speed, if I take hands from steering wheel on highway car goes straight.
Could it be related to VSA?

Let me help you!
On cars with power steering, the steering is assisted hydraulically. In order for the hydraulic fluid to move, it needs to be pumped. The power steering pump is connected via belt to your engine. This has a couple of consequences:
- idle engine speed: the pump produces enough flow to turn the steering wheel.
- higher engine speed: the pump produces more than enough flow to turn the steering wheel
So at higher speeds, it's easier to turn. As you slow or stop, steering becomes slightly harder. With the engine off, it's quite a bit hard to turn the steering wheel.
As a side note, since the pump is always pumping, it's wasting power which means it's wasting fuel. Some people install new pulleys (either lighter-weight or over-size). This can affect power steering slightly (if noticeable). Although it could cause problems too, like not being able to charge your battery properly.
VSA only turns on when it detects one of the wheels slipping (I believe...i'm half-asleep right now). When it does go on, an indicator light lights up and you'll hear beeping.
