DTC P0230: Fuel Pump Relay Control Circuit: Description

Fuel pump relay is located in left instrument panel fuse block. ECM controls fuel pump motor by supplying a ground to fuel pump relay. Fuel pump runs continuously whenever engine is running or runs for 2 seconds if ignition is turned on and engine is not cranked. ECM controls an internal driver that supplies a ground to fuel pump relay coil whenever fuel pump relay is commanded on. Relay coil circuit is monitored for low and high voltage and open circuit faults. DTC sets when ECM detects an open fuel pump relay control circuit when relay is commanded off.
