1.  Turn the ignition switch to the ON position and verify that the oil pressure warning light illuminates.

2.  Start the engine and verify that the oil pressure warning light turns off.

•  If the oil pressure warning light does not illuminate or remains illuminated, inspect the BCM and the related wiring harnesses. (See DTC INSPECTION [BCM].)

―  If the related wiring harnesses are normal, inspect the oil pressure. (See OIL PRESSURE INSPECTION [ZJ, ZY].) (See OIL PRESSURE INSPECTION [MZ-CD 1.4 DI Turbo].) (See OIL PRESSURE INSPECTION [MZ-CD 1.6 (Y6)].)

•  If the oil pressure is normal, replace the oil pressure switch.
