the position sensor is mounted on the lower portion of the steering column. the SIGNAL goes to the bcm . the EVO electronic variable orifice is mounted on the back of the power steering pump. this varies effort to the steering by controlling power steering pump hydr fluid flow. the two components work to increase or decrease power steering effort . this will not cause the steering to wander or be sloppy..

It was mentioned alignment as a possible cause. this reminded me that if your vehicle has dropped in the front [lower vehicle height] this will cause the toe to be off by having your front wheels pointing outward [positive toe] this will create a bad tracking when going down the road at highway speed every time you hit even a small road surface defect.

If the vehicle has dropped , first get that fixed , then if it is still a problem have the alignment checked ..

DO NOT GO TO A TIRE SHOP !

THE toe issue should show the inner tire treads worn more than the outer.
