Power Steering Switch

  1. Power steering switch is used to increase idle during steering operation. Switch is located in piping on rear of power steering pump.
  2. Install ohmmeter on switch terminals. With engine running, no continuity should exist while wheels are in the centered position. Turn steering to maximum turning radius in both directions. Continuity should exist. Replace switch if defective.
