Oil Injection Pump
The oil injection pump is an electric (55 V) actua-
tor style pump. It draws oil from the oil tank and
supplies pressurized oil to the oil manifold. The
EMM
supplies 55 V and controls activation of the
pump.
The oil manifold distributes the oil supplied by the
pump.
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, or the circuit is open, the
EMM
