J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
3563-13 1785-13 Engine Intake Manifold #1 Absolute Pressure : Out of Calibration During calibration, the pressure offset must be within 15 kPa (2.2 psi) of the barometric pressure sensor.
During calibration, the pressure offset value is outside the acceptable range.
The code is logged. The Electronic Control Module (ECM) checks the signals from intake manifold pressure sensor 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 sensor. During this time, the ECM compares the signal from the barometric pressure sensor with the signal from the intake manifold pressure sensor.The 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, a 3563-13 (1785-13) 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 and intake manifold air 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 in order to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged -3 or -4 codes for the intake manifold pressure sensor or the barometric pressure sensor.
F. Use the electronic service tool in order to monitor active diagnostic codes or recently logged diagnostic codes. Look for an active or logged 3563-13 (1785-13) code.
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" in order 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: A 3563-13 (1785-13) diagnostic code is active.
Proceed to Test Step 3.
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) for the duration of 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 and intake manifold air temperature are now at least 5° C (41° F).
F. Check for an active 3563-13 (1785-13) 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 diagnostic codes for the pressure sensors.
If there are logged diagnostic codes for the intake manifold pressure sensor, the fault may be intermittent.
Refer to Troubleshooting, "Electrical Connectors - Inspect" in order to identify intermittent faults.
Result: There is an active 1785-13 diagnostic code.
Proceed to Test Step 3.
3. Check the Barometric Pressure Sensor
A. Turn the keyswitch to the OFF position.
B. Install a new barometric pressure sensor.
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 3563-13 (1785-13) code is active.
Proceed to Test Step 4.
4. Check the Intake Manifold Pressure Sensor
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the intake manifold pressure 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 3563-13 (1785-13) diagnostic code for the suspect sensor.
Diagnostic code
Result: There is an active 3563-13 (1785-13) code or the sensor is blocked
Temporarily connect a new intake manifold pressure sensor to the harness. Use the electronic service tool to confirm that the repair eliminates the fault.
If the fault is eliminated, permanently install the new sensor. Refer to Disassembly & Assembly for the correct installation procedure.
If the fault is still present, contact the Dealer Solutions Network (DSN).
Result: There is no active -13 code.
Check that the sensor port is free of blockages or restrictions.
Install the sensor. Refer to Disassembly & Assembly for the correct installation procedure.
Turn the keyswitch to the ON position. Run the engine at idle speed for 5 minutes.
Turn the keyswitch to the OFF position. Ensure ECM is fully powered-down.
Turn the keyswitch to the ON position. Do not start the engine. Wait for 10 seconds. Confirm code is not active.
Use the electronic service tool to clear all logged codes.
If the fault is still present, contact the Dealer Solutions Network (DSN).
