Oil Pressure Switch Test (Non-Turbo A/T)

  1. Remove switch. Using an ohmmeter, check for continuity between switch casing and switch connector terminal while applying air pressure to switch.
  2. Continuity should be present when pressure is less than 7.1 psi (0.54 kg/cm2 ) and continuity should not be present when pressure is greater than 43 psi (3.0 kg/cm2 ). If switch does not operate within specifications, replace switch.
