Power Steering Pressure Control Valve: Testing and Inspection

- Faults developing in control valve and pinion assembly will necessitate renewal of control valve and pinion. No adjustment or repair is permissible.
- Check tires, tire pressure and steering geometry before testing.

CAUTION: During the test procedures, do not turn steering excessively, as this will produce high pressure resulting in irreparable damage to gauge.

Steering Pressure Test:

- Fit a 7 kgf/cm (100 psi) pressure gauge in feed line from pump, start engine and allow to idle.
- Gauge should register 2,8 kgf/cm2 (40 psi) approximately.
- Turn steering wheel slightly to right or left.
- Pressure should increase by an equal amount irrespective of direction of steering wheel rotation Any unbalance will be indicated by a slight fall in pressure on either side before rising.
- Stop and re-start engine and check that steering does not kick to one side.
