The reading for Exhaust Gas Pressure 1 is believed to be correct, but it has gone moderately above the normal operating range. This is the middle of the three "above range" levels (FMI 15, 16 and 0); it often triggers a derate and will escalate if the condition continues.
It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays active.
On a generic J1939 scan tool, or on the dash of a Freightliner, Kenworth, Peterbilt, International or Volvo chassis, the same fault is shown as SPN 1209 FMI 16 rather than as Cummins code 2764; an OBD-II reader shows it as P0474. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.
Fault code 2764 is defined in the fault tables of the Cummins calibrations we have analysed and is one of the more commonly enabled codes, so it is a real, current code rather than a legacy number.

Questions about code 2764
What does Cummins fault code 2764 mean?
Cummins 2764 is "Exhaust Gas Pressure 1 - Data Valid But Above Normal Operating Range - Moderately Severe Level". It maps to SPN 1209 FMI 16 and OBD code P0474. The reading for Exhaust Gas Pressure 1 is believed to be correct, but it has gone moderately above the normal operating range. This is the middle of the three "above range" levels (FMI 15, 16 and 0); it often triggers a derate and will escalate if the
Which lamp does fault code 2764 turn on?
Amber WARNING lamp: It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays active.
How do I clear or permanently delete Cummins code 2764?
An active code goes inactive on its own once the condition is gone; the inactive record stays in the ECM fault history until it is cleared with Cummins INSITE (or a J1939 tool that supports the DM3 / DM11 clear). If the code keeps coming back because the part is gone, disconnected or not worth repairing, the lasting fix is to disable fault 2764 in the calibration: upload your .xcal to the ECFG Superstore file service, custom DTC delete from $150 (up to 30 codes), full DPF / EGR / SCR delete $500, and flash the returned file with Calterm or INSITE.
