DIAGNOSIS AND TESTING - BOOST PRESSURE …
OPERATIONWhen the intake manifold PRESSURE is low (highvacuum) sensor voltage output is volts at theECM. When the intake manifold PRESSURE is high dueto turbo BOOST , sensor voltage output is sensor receives a 5-volts reference from theECM. sensor ground is also provides by the ECM uses BOOST PRESSURE combined with intakeair temerature to determine the volume of air enter-ing the engine (Fig. 2). DIAGNOSIS AND TESTING - BOOST PRESSURESENSORIf the BOOST PRESSURE sensor fails, the ECM recordsa DTC into memory and continues to operate theengine in one of the three limp-in modes. When theECM is operating in this mode, a loss of power willbe present, as if the turbocharger was not best method for diagnosing faults with the boostpressure sensor is with the DRB III scan tool. Referto the Diesel Powertrain Diagnostic Manual for to On-Board Diagnostics in Emissions Con-trol System for a list of Diagnostic Trouble Codes(DTC s) for certain fuel system (1) Disconnect the negative battery cable.
(2) Position the boost pressure sensor above access hole in the charge air pipe and push down to fit flush (Fig. 3). (3) Install the bolts and tighten to 44 lbs. in. (5
