Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The code P0089 can be set by any of the following,
Defective Fuel Metering Valve N276
Defective Fuel Pump Control Module J538
Defective Low Pressure Side Fuel Pressure Sensor G410 with the Low Pressure Side Fuel Pressure Sensor being the most common thing to fail. To check this you are going to need to do some testing. See the steps in the link below, copy and paste the link toy our browser to open and view them.
