Boost Pressure System Monitor — I/M Boost Pressure System Monitor
Boost Pressure System Monitor
The boost pressure system is used on diesel engines to increase the pressure produced inside the intake manifold to a level greater than atmospheric pressure. The pressure increase helps to ensure compete combustion of the air-fuel mixture.
The Boost Pressure System Monitor checks for component integrity and system operation, and tests for faults in the system.
The computer runs this Monitor once per trip.
The Boost Pressure System Monitor is a “Two-Trip” Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does
not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL “On,” and saves the code in its long-term memory.
