Event Codes
CDL Code Description System Response
E583(1) High Air Inlet #1 Differential Pressure The left-side air filter differential pressure is above the trip point pressure for the delay time.
The code is logged.
E583(2) High Air Inlet #1 Differential Pressure The left-side air filter differential pressure is above the trip point pressure for the delay time.
The code is logged.
The engine power is derated.
E584(1) High Air Inlet #2 Differential Pressure The right-side air filter differential pressure is above the trip point pressure for the delay time.
The code is logged.
E584(2) High Air Inlet #2 Differential Pressure The right-side air filter differential pressure is above the trip point pressure for the delay time.
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, 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"
"Turbocharger #2 Compressor Inlet Pressure"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.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 readings for the turbocharger compressor inlet pressure sensor will be approximately the same value that is reported by the atmospheric pressure sensor. If the readings do not agree, troubleshoot the sensor circuit(s) for the suspect sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test" for information that is related to troubleshooting the circuits.
