Case IH 3293 (DTC 2265) - ECU – ECU:

Check for concurrent active faults, specifically 3106 (DTC 1145) - 'Fuel pressure relief valve reached maximum allowed opening count'. Resolve these first.

Verify that the tractor's battery power supply has not been connected to an external power supply (such as a jump-starter or external charger), as voltage spikes can cause erratic sensor readings.

Check if the machine recently experienced an engine overspeed condition (e.g., traveling downhill with a heavy load), which can temporarily spike fuel rail pressure and trigger this code.
