The following background information is related

to the following procedure:

The injection actuation pressure control valve

regulates the high pressure oil to the injectors

through a high pressure rail. The high pressure oil

manifold is used to actuate the injectors and the

high pressure oil manifold is used to control the fuel

injection pressure. The injection actuation pressure

control valve relieves excess high pressure oil

back to the sump. The ECM controls the operation

of the injection actuation pressure control valve

by monitoring the engine rpm and the injection

actuation pressure sensor.
