Code P0232 2016 Chevrolet Silverado Description

The Engine Control Module (ECM) supplies voltage to the fuel pump driver control module when the ECM detects that the ignition is on. The voltage from the ECM to the fuel pump driver control module remains active for 2 s, unless the engine is in crank or run. While this 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 fuel pump driver control module monitors the fuel pump voltage to determine if the fuel pump is functioning as commanded. The Diagnostic Trouble Code (DTC) will be set if the fuel pump driver control module detects that the fuel pump output circuit voltage is greater than 4.0 V for 1 s when the voltage should be 0 V.
