Code P12A6 2014 Chevrolet Silverado Description

The Engine Control Module (ECM) provides ignition voltage to the Fuel Pump Driver Control Module whenever the engine is cranking or running. The ECM enables the Fuel Pump Driver Control Module as long as the engine is cranking or running, and ignition system reference pulses are received. While this enables voltage is being received, the Fuel Pump Driver Control Module supplies a varying voltage to the fuel tank fuel pump module in order to maintain the desired fuel line pressure. The Diagnostic Trouble Code (DTC) will be set if the ECM state of the fuel pump enable circuit does not match the state of the fuel pump enable circuit sensed by the fuel pump driver control module for greater than 0.5 s.
