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.
3609–13 DPF #1 Intake Pressure : Out of Calibration The ECM detects the following conditions:
The offset between the DPF inlet pressure and the barometric pressure is outside the acceptable range during initialization check.

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.
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: There are multiple -13 diagnostic codes active.
Proceed to Test Step 3.
Result: There is an active -13 diagnostic code for only one sensor.
Proceed to Test Step 4.
2. Ensure that the Systems are Fully Thawed
A. Move the machine into an environment where the ambient temperature is greater than 5° C (41° F) during any troubleshooting.
B. If engine has been operated or stored in cold ambient conditions where there is a risk of ice formation on a sensor or sensor pipes, run engine until the coolant temperature exceeds 65° C (149° F) for 20 minutes.
C. Turn the keyswitch to the OFF position. Wait for at least 20 seconds. The electronic service tool will disconnect.
D. Turn the keyswitch to the ON position.
E. Verify that coolant temperature, intake manifold air temperature, and NRS temperature are all now at least 5° C (41° F).
F. Check for active -13 diagnostic codes.
G. Check that the suspect sensor is installed correctly. Check that the suspect sensor is fully seated into the engine.
Diagnostic codes
Result: There are no active -13 codes.
Repair: The fault was caused by ice in the system that has now been thawed. Return the unit to service
Result: There are multiple -13 diagnostic codes active.
Proceed to Test Step 3.
Result: A single -13 code is active or logged.
Proceed to Test Step 4.
3. Check the Barometric Pressure Sensor
A. Turn the keyswitch to the OFF position.
B. Install a new Electronic Control Module (ECM).
Note: The Barometric Pressure Sensor is located within the ECM so cannot be replaced separately. To replace the Barometric Pressure Sensor, the ECM must be replaced.
C. Turn the keyswitch to the ON position. Do not start the engine.
Note: Wait at least 10 seconds in order for the diagnostic codes to become active.
D. Monitor the status parameter for the suspect sensor on the electronic service tool.
Barometric pressure sensor fault
Result: There is no active -13 code. The fault was caused by a faulty barometric pressure sensor.
Use the electronic service tool to clear all logged codes. Return the unit to service.
Result: A -13 code is active.
Proceed to Test Step 4.
4. Check the Suspect Pressure Sensor
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the suspect sensor and remove the sensor from the engine.
C. Check the sensor for a blockage.
D. Temporarily reconnect the sensor to the harness. Do not install the sensor on the engine.
E. Turn the keyswitch to the ON position. Do not start the engine.
F. Check for an active -13 diagnostic code for the suspect sensor.
Barometric pressure sensor fault
Result: There is an active -13 code or the sensor is blocked
Temporarily connect a new sensor to the harness. Use the electronic service tool to confirm that the repair eliminates the fault.
If the fault
