Code P019, Shorted Fuel Pump Circuit: Notes

WARNING: This page is about a different car, the 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors fuel pump feedback voltage for 4 seconds after ignition is turned on without engine being cranked. Fuel pump relay will be energized for 2 seconds and then de-energized. If voltage on fuel pump feedback does not drop to less than 7 volts during first 4 seconds after ignition is turned on (engine off), Code P019 will set, indicating voltage on circuit No. 120 with fuel pump relay de-energized.
