fold. The EMM supplies 55 V and controls
activation of the pump.
The oil manifold distributes the oil supplied by the
oil injection pump to the crankcase. On 3.3 L mod-
els oil is also distributed to the rear oil manifold.
Electrical Circuit (55 V)
The oil injector is powered by the 55 V electrical
circuit. The
EMM controls pump operation by rap-
idly connecting and disconnecting the pump’s
internal coil to ground.
The EMM monitors the oil injection pump electri-
cal circuit. If circuit voltage is beyond the specified
range (open circuit), the
EMM :
Oil Pressure Sensor
The oil pressure sensor reacts to changes in oil
manifold pressure. The
EMM supplies and moni-
tors electrical current to the sensor.
•
The sensor provides an output voltage to the
EMM based on oil manifold pressures.
•
5 VDC Input on RED wire
•
0.5 - 4.5 V Output on TAN / WHITE wire
•
Ground on BLACK wire
The EMM monitors the oil pressure sensor’s elec-
trical circuit. If circuit voltage is beyond the speci-
fied range (< 0.15 V, > 4.85 V), the
EMM :
If oil pressure is below expected range (< 0.4 V),
the
EMM :
If oil pressure is above expected range (> 4.6 V),
the
EMM :
