Oil Pressure Switch Inspection

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that the oil pressure warning light illuminates when the ignition switch is at the ON position.
  2. Verify that the oil pressure warning light goes off when the engine is started.
    • If the oil pressure warning light does not illuminate or remains illuminated, inspect the related wiring harness.
    • If the oil pressure is normal, replace the oil pressure switch.
