OILING SYSTEM
COMPONENTS
8
Two pulse hoses connect the pump to pulse fit-
tings on the front of the cylinder/crankcase.
• V4 Models – cylinders 1 and 3
• V6 Models – cylinders 1 and 4
Oil Injector-Manifold
The oil injector-manifold distributes the oil sup-
plied by the oil lift pump. A pressure-sensing
switch monitors oil injection pressure.
Oil Injector-Manifold Components
•
40 V oil injector
• Oil distribution manifold
• Oil pressure switch
• Pressure regulator (oil return hose)
• Oil distribution hoses
• Oil to fuel check valve
Oil Pressure Switch
The oil pressure switch is located in the oil injec-
tor-manifold and reacts to changes in oil manifold
pressure. The
EMM
supplies and monitors electri-
cal current to the switch.
The switch opens or closes based on the following
oil manifold pressures:
Refer to Oil Pressure Switch Test on p. 224.
Service Code 38
A faulty electrical circuit or an inoperative pres-
sure switch activates service code 38 (no oil sen-
sor feedback or lack of oil pressure) and the
EMM
:
Service Code 39
If no oil pressure is detected during startup, the
EMM
initiates an oil injector “recovery mode” to
pressurize the system. If inadequate oil pressure
is still detected after the recovery mode is com-
pleted, the
EMM
