DTC P025A-12: Fuel Pump Module "A" Control Circuit High Circuit Short to Battery; DTC P0627-12: Fuel Pump "A" Control Circuit Short to Battery [11/2024 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The fuel pump control ECU performs PWM (Pulse Width Modulation) control to control the fuel pump (for low pressure side) speed steplessly over a wide range.

The fuel pump control ECU controls the speed of the fuel pump (for low pressure side) by switching the current of FPU, FPV and FPW based on operation signals output from the ECM.
