Low Oil Pressure Caution System
P
CDI unit
The oil pressure switch activates the low oil pres-
sure caution system when engine
oil pressure
drops
below 2
psi
(15 kPa).
•
Caution lamp turns
ON
• Buzzer sounds (remote models)
• Engine speed is reduced to approximately 2000
RPM
through intermittent ignition signals.
To
cancel the low oil pressure caution warning:
• Stop engine and check engine oil level. Refill to
correct
level.
•
The caution system is reset when oil pressure
reaches 2
psi
(15 kPa), over 1500 RPM, for 1.5
seconds.
