Oil Pressure Switch Repair procedures

Removal and
Installation

  1. Disconnect the battery negative terminal.
  2. Remove the engine room under cover.

     

    (Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

  3. Disconnect the oil pressure switch connector (A).
  4. Remove the oil pressure switch (B).

Tightening torque : 9.8 - 11.8 N*m (1.0 - 1.2 kgf*m, 7.2 - 8.7 lb*ft)

  1. Install in the reverse order of removal.

Warning

When installing the oil pressure switch, apply seal lock to the thread.

Seal lock : THREEBOND 2403

Thickness : 0.2 - 0.4 mm (0.008 - 0.016 in.) Inspection

Inspection

  1. Check the continuity between the terminal and the body with an ohmmeter.

     

    If there is no continuity, replace the oil pressure switch.

  1. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed, replace the switch.
  2. If there is no continuity when a pressure of 50 kPa (0.50 kgf/cm², 7.25 psi) is applied through the oil hole, the switch is operating properly.

Check for air leakage. If air leaks, the diaphragm is broken. Replace it.
