P0089 Volvo s60 2005

Question

My fuel pump, filter, and pressure regulator have been replaced, but the code still registers. What should my next plan of action be?

Answer 1

P0089 Fuel pressure Faulty signal

With this code condition you check the fuel pressure and compare it to the actual fuel pressure and the fuel pressure signal, If you already replaced the fuel filter and regulator the only componenet left is the fuel pressure sensor.This code P0089 is more a fuel pressure sensor fault than the fuel pump and regulator.
