DTC P0230-11: Fuel Pump Primary Circuit: General Description
WARNING: This page is about a different variant/trim than selected.
The PCM operates the relay by controlling the control line of the fuel pump relay according to the operating conditions. When the ignition "ON", the PCM operates the relay for a period of time to generate fuel pressure, and if the start signal (engine RPM above a threshold) is input, the relay is driven to operate the fuel pump.
