Code P1255 Cadillac Description

The Engine Control Module (ECM) supplies voltage to the fuel pump control module when the ECM detects that the ignition is on. The voltage from the ECM to the fuel pump control module remains for 2 seconds unless the engine is cranked or run. While this voltage is being received, the fuel pump control module supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel pressure. The Diagnostic Trouble Code (DTC) will be set if the fuel pump control module detects an over-temperature fault.
