Code P0230 Pontiac Description
When you turn the ignition switch to the ON position, the Powertrain Control Module (PCM) activates the in-tank fuel pump. The fuel pump remains on as long as the PCM receives reference pulses from the electronic ignition system. If there are no reference pulses, the PCM turns the fuel pump off after about 2-3 seconds. The PCM controls the fuel pump relay by applying B+ to the control circuit via an internal switch called a driver. The primary function of the driver is to supply a voltage to the fuel pump relay. The driver has a fault line which the PCM monitors. When the PCM commands the fuel pump on, the voltage of the control circuit should be high (near battery voltage). When the PCM commands the control circuit to the fuel pump OFF, the voltage potential of the circuit should be low (near 0 volts). This DTC sets when the PCM detects the fuel pump control circuit is shorted to ground.
