Information:
On engines with serial numbers 7LG1-7499, Inlet Air Temperature Sensors have Deutsch HD Connectors, 7LG7500-UP Inlet Air Temperature Sensors have DT Connectors.Schematic
Diagnostic Codes
Functional Test
P-527: Oil Pressure Circuit Test
System Operation
The 3176 system monitors oil pressure with a sensor located in the oil gallery (right side of engine). The oil pressure sensor is supplied with electrical power by the 5 volt sensor supply voltage from the ECM. Note that the 3176 uses oil pressure only as an engine protection function (available for 7LG7500-UP engines). Lack of oil pressure does not prevent the 3176 ECM from starting the engine. The 3176 ECM will still try to start the engine even if oil pressure is low.The 3176 system monitors oil pressure following engine start up and may show a 100-01 Low Oil Pressure Warning Diagnostic Code (46). The Diagnostic Code will not be logged for the first 15 seconds following engine start up, only ACTIVE.The Oil Pressure Sensor can measure oil pressure from 0 kPa (0 psi) to 690 kPa (100 psi).The 3176 oil pressure sensor is supplied with electrical power by the 5 volt sensor supply voltage from the ECM through connector J4/P4 Pin 10 to the Oil Pressure Sensor Connector P17/J17 Pin A. The Oil Pressure Sensor signal line routes from P17/J17 Pin C to J4/P4 pin 27. The Sensor Common routes from J4/P4 Pin 35 to P17/J17 pin B. the +5 V supply is shared with the Coolant Temperature, Inlet Air Temperature, and Coolant Level (if installed) Sensors. The Sensor Common is shared by the Coolant Temperature, and Inlet Air Temperature Sensors.Schematic

Functional Test
ECAP Example Screen of Oil Pressure Reading P-528: Boost Pressure Circuit Test And Sensor Calibration
System Operation
The 3176 system monitors boost pressure with a sensor located inside the Transducer Module. The boost pressure sensor is supplied with electrical through the Transducer Module Connector (inside the module) pin 1 (+8V). The signal routes through pin 2 (Boost Pressure) and Sensor Common is pin 3. The sensor can only be replaced by replacing the transducer module.The boost pressure is used to reduce smoke emissions during acceleration. 3176 limits the amount of fuel injected until certain boost pressures are reached. It does this by converting boost pressure to "FRC Fuel Post." (as shown on the ECAP status display). The FRC Fuel Pos. is electronic limit on the amount of fuel injected and is based on a ratio of fuel to air being supplied to the cylinders. It operates in a manner similar to the fuel ratio control on an engine with a mechanical governor.The inlet air hose from the air cleaner to the transducer module must be installed. The air inlet serves as a vent for the transducer module and is required for proper operation of the boost pressure sensor.The 3176 Boost Pressure Sensor must be calibrated for a zero boost condition with the engine off. Calibration is accomplished electronically without the need for manual adjustments. The sensor must be recalibrated whenever the ECM or transducer module has
