P1172

CIRCUIT DESCRIPTION
The fuel pump is located on the left frame rail between the fuel tanks. The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. The ECM energizes the fuel pump relay, which applies power to the fuel pump. Fuel is transferred from the rear fuel tank to the front fuel tank in order to ensure all of the usable fuel volume is available to the engine. This Diagnostic Trouble Code (DTC) sets when the ECM commands the transfer fuel pump ON and a predetermined change in the front and rear fuel level sensors does not occur.
