Inspection

  1. Using an ohmmeter, check continuity between the terminal and the body. If there is no continuity, replace the oil pressure sensor.
  2. Check continuity between the terminal and the body while pressing the thin wire. If there is continuity even when the thin wire is pressed, replace the switch.
  3. If continuity is not present when a pressure of 50 kPa (0.50 kgf/cm², 7.25 psi) is applied through the oil hole, the switch is operating correctly. Check for air leakage. If air leaks, the diaphragm is broken. Replace it.
