4.5 Oil Level Sensor Fails to Stop Engine with Low Oil
No continuity
No continuity
Continuity
Completely drain the oil, disconnect the
oil sensor wire connector, and check
the continuity between the white wire
and chassis ground (section 4.5.1).
Check and repair all wire
connections as necessary.
Replace the oil level sensor if
necessary (section 5.7 and 5.12).
Continuity
Follow step 1 in (section 4.13) to
access the voltage regulator. Check the
continuity of the white wire between the
low oil sensor (section 4.5.1, Fig. 23)
and the low oil sensor connector on the
voltage regulator (section 4.13, Fig. 30).
Repair or replace the wire
between the low oil sensor and
the voltage regulator.
If the voltage from the voltage regulator is
reaching the ignition/indicator module, and
the engine is not being shut down and/or
the low oil light is not being illuminated,
then replace the ignition/indicator module.
Good Voltage
No or low
voltage
Replace the voltage regulator.
Check the continuity of the pink wire
between the voltage regulator and the
ignition/indicator (section 4.13, step 6).
Continuity
No continuity
Repair or replace the wires
between the voltage regulator
and the ignition/indicator module.
Verify that the voltage regulator supplies
12.5-14.5V to the ignition/indicator module
when the white wire of the voltage regulator
is grounded (section 4.13, step 6).
