OIL LEVEL WARNING SYSTEM
CHECK <4G6>
1. Check that the proper amount of oil has been filled.
2. When the ignition switch is turned to ON (do not start
the engine), check that the oil level warning lamp
illuminates.
NOTE
If the oil level warning lamp does not illuminate, the cause
is probably a blown lamp, or a malfunction in the relay.
3. When the engine is started, check that the oil level warning
lamp turns off.
If the oil level warning lamp will not go out, disconnect
the connector of the oil level relay and measure the voltage
of the No.1 terminal on the harness side of the connector
while idling the engine in order to confirm that it is the
same as the battery voltage.
NOTE
(1) If the voltage at the connector is the same as the
battery voltage, the problem is probably a malfunction
of either the oil level relay or the oil level sensor.
(2) If the voltage at the connector is lower than the battery
voltage, the problem is probably a malfunction of either
the alternator or the wiring harness.
4. Disconnect the oil level sensor connector. Check that
the oil level warning lamp illuminates after approximately
40 seconds.
If the oil level warning lamp does not illuminate, replace
the oil level relay.
5. Check the continuity between the oil level sensor
terminals.
