Event Codes for a high differential pressure for the air inlet system
Code Description System Response
E583(1) High Air Inlet #1 Differential Pressure The 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 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 circuitsRecommended Actions

Troubleshooting Test Steps Values Results
1. Air Filter Element
A. Check the air intake system for plugged air filters or for damaged air filters.
B. If the engine is equipped with an air intake precleaner, verify the proper operation of the air intake precleaner.
Air Filter Element
Result: The air filter element is damaged.
Repair: Replace the air filter element.
Result: The air filter element is not damaged.
Proceed to Test Step 2.
2. Air Inlet Piping
A. Check the air inlet piping for damage or restrictions.
Air Inlet Piping
Result: The air inlet piping is damaged or restricted.
Repair: Repair or replace the air inlet piping.
Result: The air inlet piping is not damaged or restricted.
Proceed to Test Step 3.
3. Atmospheric Pressure Sensor, Turbocharger Compressor Inlet Pressure Sensors, and/or Sensor Circuits
A. Use Cat ET to compare the status of the following parameters while the engine is off:
• Atmospheric Pressure
• Turbocharger #1 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 3 minutes. Cat ET will report "Conditions Not Met" for these parameters prior to this delay time.
B. 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 circuits for the suspect sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test".
Sensors
Result: The sensors are NOT OK.
Repair: Repair or replace the faulty sensors.
Result: The sensors are OK.
