Event Code
J1939 Code and Description Conditions which Generate this Code System Response
107-15 Engine Air Filter 1 Differential Pressure : High - least severe (1) The air filter differential pressure is above the trip point pressure for the delay time. The code is logged.
The ECM may derate the engine.
107-16 Engine Air Filter 1 Differential Pressure : High - moderate severity (2) Probable Causes
Air filter element
Air inlet piping
Atmospheric pressure sensor, turbocharger compressor inlet pressure sensors, and/or sensor circuits
EnclosureNote: A high air inlet restriction may cause oil to be pulled into the air system through the Closed Crankcase Ventilation (CCV) system. After the return of the crankcase fumes from the CCV into the air intake, inspect the air intake system for oil. If oil is found, thoroughly clean the air intake system.Recommended Actions
Air Filter Element
Check the air intake system for plugged air filters or for damaged air filters. If the engine is equipped with an air intake precleaner, verify the proper operation of the air intake precleaner.Air Inlet Piping
Check the air inlet piping for damage or restrictions. Repair the piping or replace the piping.Enclosure
Check that the engine has been installed in an enclosure that is sufficiently ventilated. Repair the ventilation for the enclosure.Atmospheric Pressure Sensor, Turbocharger Compressor Inlet Pressure Sensors, and/or Sensor Circuits
Use Cat ET to compare the status of the following parameters while the engine is off:
"Atmospheric Pressure"
"Turbocharger #1 Compressor Inlet Pressure (absolute)"
"Turbocharger #2 Compressor Inlet Pressure (absolute)"Note: The status for air filter restriction is a calculated value. Before Cat ET reports the status parameters for air filter restriction, the engine must be running for three minutes. Cat ET will report "Conditions Not Met" for these parameters prior to this delay time.Check that the sensors are correctly wired.Cat ET will report the status for "Atmospheric Pressure" as the barometric pressure that is for the surrounding area. With the engine off, the readings for the turbocharger compressor inlet pressure sensors will be approximately the atmospheric pressure. If the readings do not agree, troubleshoot the sensor circuit for the suspect sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test".
