1. DTC Descriptor:
DTC P0230
The power pump relay coil working voltage is provided by ECM. ECM provides power through ECM harness connector EO35 terminal
No.71 to pump relay terminal No.1. The fuel pump is grounded through the terminal No.2, pump relay pull-in. ECM has an internal
detection circuit. By monitoring the feedback voltage ECM determines whether the control circuit is open, short to ground or short
to voltage.
