Refer to the following table for the contol parts list (CPL), engine model, engine horsepower rating, and corresponding
rated turbocharger boost pressure.
Note: Measurement of boost pressure is not a shortcut to logical troubleshooting. Low power can be caused by the
fuel used, filter maintenance, and several engine components. Follow the logic charts for Engine Power Output Low,
and measure boost pressure as indicated. Refer to this section, General Information, for measurement instructions.
These pressures are valid only at rated conditions (rated speed and power). Any attempt to use the values at engine
speeds and loads other than those specified will result in an incorrect diagnosis.
