Oil Pressure Switch Test
WARNING: This page is about a different car, the 1996 Honda Civic del Sol and 1995 Honda Civic del Sol. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect Yellow/Red wire from oil pressure switch (located above oil filter). Using ohmmeter, check continuity between oil pressure switch terminal and ground. With engine off, continuity should exist. With engine running, continuity should not exist. If switch fails to operate as described, check engine oil level and oil pressure. See OIL PRESSURE SPECIFICATIONS table. If oil level and oil pressure are okay, replace oil pressure switch.
