SPN 98 Low Oil Level
Circuit Description
The low oil level sensor is mounted within the engine at the
base of the crankcase. The low oil level sensor uses run-
sense technology to only detect low oil level after the engine
is started.
If low oil level triggers SPN 98, engine operation is stopped.
The fault is reset when the key switch is turned off and the
ECM powers down. Low oil level is monitored at the next
engine start cycle.
Possible FMIs
The possible FMIs for SPN 98 are as follows:
FMI Description
1 Low oil level error

Step Action Yes No
1 1. Turn Ignition OFF.
2. Check engine oil level by verifying that the oil level is within the cross hatch
pattern on the dipstick. See A , within the image below.
3. Is the engine oil level low?
