System Operation Description:Table 1 lists the diagnostic trouble codes for the clean gas induction system (CGI).

Diagnostic Trouble Codes for the CGI System
J1939 Code Description Comments
520192-15 CGI Mass Flow Rate : High - Least Severe (1) The flow of clean gas is excessive. The Aftertreatment Regeneration Device (ARD) was not affected by the excessive flow of clean gas.
520192-16 CGI Mass Flow Rate : High - Moderate Severity (2) The ARD failed to ignite or the ARD lost combustion. The flow of clean gas was excessive.
520192-18 CGI Mass Flow Rate : Low - Moderate Severity (2) The flow of clean gas is consistently low. A snapshot is triggered. The code is logged. Engine power is derated.
Follow the troubleshooting procedure in order to identify the root cause of the problem. System Operation Description

(1) Tubing
(5) Absolute pressure sensor
(6) Differential pressure sensor The CGI system routes clean gas from the outlet of the Diesel Particulate Filter (DPF) to the inlet of the turbocharger. The CGI system consists of the following components:CGI cooler - The CGI cooler uses engine coolant to cool the clean gas.Sensor Group - Refer to Illustration 3.

(5) Absolute pressure sensor
(6) Differential pressure sensor
(7) Temperature sensor
(8) Low pressure tube
(9) High pressure tube The sensor group consists of these components:Venturi - The venturi is a restriction in the duct between the DPF and the turbocharger. Two pressure taps on the venturi provide connection points for tubing.Tubing - Tubing connects the venturi's pressure taps to two pressure sensors.Sensors - Three sensors sense the parameters of the clean gas.The sensor group produces electrical signals that indicate the values of the following parameters:CGI Temperature - This is the temperature of the clean gas in the duct.CGI Absolute Pressure - This is the absolute pressure of the clean gas in the duct.CGI Differential Pressure - This is the pressure drop across the venturi.Electrical wiring sends the signals from the sensors to the Engine Control Module (ECM). The ECM uses the signals to determine the mass of the clean gas that is flowing into the turbocharger.The ECM creates a pulse width modulated signal (PWM) that indicates the amount of clean gas that is desired. Wiring sends the PWM signal from the ECM to the CGI control group.

The coil creates a magnetic field that is detected by the actuator.Actuator (11) - The actuator uses pressurized engine oil to convert the coil's magnetic field to rotation of a shaft. The shaft engages the valve assembly.Valve Assembly (10) - The
