Engine Events
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.
107-16 Engine Air Filter 1 Differential Pressure : High - moderate severity (2) The code is logged.
The engine power is derated. Probable Causes
Air filter element
Air inlet piping
Atmospheric pressure sensor, turbocharger compressor inlet pressure sensors, and/or sensor circuits
EnclosureRecommended 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, Inlet Air Differential Pressure Sensor, and/or Sensor Circuits
Use Cat ET to compare the status of the following parameters while the engine is off:
"Atmospheric Pressure"
"Inlet Air Differential Pressure Sensor"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. While the engine is off, the reading for the inlet air differential pressure sensor will be approximately the same value as the atmospheric pressure sensor. If the readings do not agree, troubleshoot the sensor circuits for the suspect sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test".
