Diagnostic Trouble Codes for the Air Filter Restriction Switch
J1939 Code Description Notes
107-2 Engine Air Filter 1 Differential Pressure : Erratic, Intermittent, or Incorrect This code indicates a fault in the circuit for the air filter restriction switch.
The Electronic Control Module (ECM) detects the following conditions:
The signal from the air filter restriction switch indicates a restriction.
The engine is not running.
The ECM has been powered for at least 6 seconds.
The warning lamp will come on.
Monitoring of air filter restriction when the engine is running will be disabled whilst this code is active. If the engine is equipped with an air filter restriction switch, the type of switch that is installed can be either "Normally Open" or "Normally Closed". The parameter for the type of switch that is installed can be set using the electronic service tool.Use the electronic service tool to check which type of switch is installed in the application before continuing with this procedure.Ensure that the parameter is set correctly for the type of switch that is installed in the application. Refer to the OEM for more information.

Diagnostic Summary for a "Normally Open" Air Filter Restriction Switch
Engine Condition Switch State Active Diagnostic Code
Not running (key on) Open Normal condition
Running Open Normal Condition (no air filter restriction detected)
Not running Closed 107-2
Running Closed 107-15 or 107-16
Table 3
Diagnostic Summary for a "Normally Closed" Air Filter Restriction Switch
Engine Condition Switch State Active Diagnostic Code
Not running (key on) Open 107-2
Running Open 107-15 or 107-16
Not running Closed Normal condition
Running Closed Normal Condition (no air filter restriction detected) Note: An active 107–15 or 107–16 diagnostic code indicates that the air inlet is restricted. Refer to Troubleshooting, "Inlet Air Is Restricted".

Troubleshooting Test Steps Values Results
1. Check the Type of Switch that is Installed and Configured
A. Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position. Do not start the engine.
C. Use the electronic service tool to check that the "Air Filter Restriction Switch Installation Status" and the "Air Filter Restriction Switch Configuration" matches the type of switch that is installed.
Switch configuration
Result: An air filter restriction switch is installed and the "Air Filter Restriction Switch Installation Status" is "Not Installed".
Use the electronic service tool to change the "Air Filter Restriction Switch Installation Status" to "Installed". Ensure that the "Air Filter Restriction Switch Configuration" matches the type of switch that is installed.
Use the electronic service to check that the repair eliminates the fault.
Result: An air filter restriction switch is not installed and the "Air Filter Restriction Switch Installation Status" is "Not Installed". The "Air Filter Restriction Switch Configuration" is "Normally Closed".
Repair: Change the "Air Filter Restriction Switch Configuration" to "Normally Open."
Use the electronic service to check that the repair eliminates the fault.
Result: An air filter is installed and the "Air Filter Restriction Switch Installation Status" is installed. The "Air Filter Restriction Switch Configuration" does not match the type of switch that is installed.
Repair: Change the "Air Filter Restriction Switch Configuration" to match the type of switch that is installed.
Use the electronic service to check that the repair eliminates the fault.
Result: An air filter restriction switch is installed. The "Air Filter Restriction Switch Installation Status" is "Installed". The "Air Filter Restriction Switch Configuration" matches the type of switch that is installed.
Proceed to Test Step 2.
2. Inspect Electrical Connectors and Wiring
A. Thoroughly inspect the terminal connections on the P1/J1 connector.
B. Thoroughly inspect the connector for the air filter restriction switch.
C. Refer to Troubleshooting, "Electrical Connectors - Inspect".
D. Perform a 30 N (6.7 lb) pull test on each of the wires in the connectors that are associated with the air filter restriction switch.
E. Check the harness for abrasions and for pinch points from the switch back to the ECM.
Damaged wire or connector
Result: A damaged wire or damaged connector was found.
Repair: Repair the damaged wire or the damaged connector.
Use the electronic service tool to clear all logged diagnostic codes. Verify that the repair eliminates the fault.
Result: All connectors, pins, and sockets are correctly connected and/or inserted and the harness is free of corrosion, of abrasion or of pinch points.
Proceed to Test Step 3.
3. Check for Active or Recently Logged 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. Do not start the engine.
D. Use the electronic service tool to check whether a "Normally Open" or "Normally Closed" air filter restriction switch is installed in the application.
E. Check for any active or recently logged diagnostic codes. Wait at least 10 seconds for activation of the diagnostic codes.
Diagnostic codes
Result: A 107-2 diagnostic code is not active.
If the diagnostic code is recently logged, an intermittent fault may exist.
Repair: Refer to Troubleshooting, "Electrical Connectors - Inspect" to identify intermittent faults.
Result: A "Normally Open" switch is installed. A 107-2 diagnostic code is active.
A short circuit condition exists in the air filter restriction switch circuit.
Proceed to Test Step 4.
Result: A "Normally Closed" switch is installed. A 107-2 diagnostic code is active.
An open circuit condition exists in the air filter restriction switch circuit.
Proceed to Test Step 6.
4. Create an Open Circuit at the Switch Connector
A. Turn the keyswitch to the OFF position.
