J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
3358-13 3385-13 Engine Exhaust Gas Recirculation Inlet Pressure : Out of Calibration The ECM detects the following conditions:
The offset between the NRS inlet pressure and the barometric pressure is outside the acceptable range during initialization check.
The offset between the NRS inlet pressure and the barometric pressure is outside the acceptable range during sensor calibration when the engine is not running.
The warning lamp will come on and the engine will derate. The code is logged.
3563-13 1785-13 Engine Intake Manifold #1 Absolute Pressure : Out of Calibration The ECM detects the following conditions:
The offset between the intake manifold air pressure and the barometric pressure is outside the acceptable range during initialization check.
The offset between the intake manifold air pressure and the barometric pressure is outside the acceptable range during sensor calibration with the engine not running.
The warning lamp will come on and the engine will derate.
The code is logged.
5019-13 3511-13 EGR Outlet Pressure : Out of Calibration The ECM detects the following conditions:
The offset between the NRS outlet pressure and the barometric pressure is outside the acceptable range during initialization check.
The offset between the NRS outlet pressure and the barometric pressure is outside the acceptable range during sensor calibration with the engine not running.
The warning lamp will come on and the engine will derate.
The code is logged. The Electronic Control Module (ECM) checks the signals from certain pressure sensors 12 seconds after the keyswitch is turned to the OFF position. The key must remain in the OFF position for a further 2 seconds in order for the ECM to check the signals from the sensors. During this time, the ECM compares the signal from the barometric pressure sensor with the signal from the following pressure sensors:
Intake manifold air pressure
NRS inlet pressure
NRS outlet pressureThe sensor signal must be within the specified range of the signal from the reference pressure sensor. If a sensor signal is out of the range, the corresponding fault code becomes active.The offset value is stored in the engine ECM. If the requirements are not met for the offset to be checked against the barometric pressure sensor, the stored value is used.

Troubleshooting Test Steps Values Results
1. Check For Active Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position. Download the "Product Summary Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
D. Use the electronic service tool to check that coolant temperature, intake manifold air temperature, and NRS temperature are all at least 5° C (41° F).
Note: Wait at least 10 seconds in order for the diagnostic codes to become active.
E. Use the electronic service tool to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged -3 or -4 codes for the pressure sensor or the barometric pressure sensor.
F. Use the electronic service tool to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged -13 code for a pressure sensor or the barometric pressure sensor.
G. Turn the keyswitch to the OFF position.
Diagnostic codes
Result: There are no active diagnostic codes for the pressure sensors.
Repair: If there are logged diagnostic codes for the intake manifold pressure sensor, the fault may be intermittent.
Refer to Troubleshooting, "Electrical Connectors - Inspect" to identify intermittent faults.
Result: One or more of the temperature sensors is reading less than 5° C (41° F).
Proceed to Test Step 2.
Result: There is an active -3 or -4 diagnostic code for a pressure sensor or the barometric pressure sensor.
Repair: Troubleshoot these codes before continuing with this procedure.
Result: 3358-13 (3385-13) and 3563-13 (1785-13) diagnostic codes are active.
Proceed to Test Step 3.
Result: There is
