Causes and Fixes P0089 Code: Fuel Pressure Regulator Performance

How to fix P0089 Code: Fuel Pressure Regulator Performance
A P0089 code is set when the computer (ECM/PCM) detects the fuel pressure is not correct.
The fuel pressure regulator, along with the fuel pump, is responsible for maintaining fuel pressure.
A P0089 code is commonly caused by a bad fuel pressure regulator failure, bad fuel pump, or bad fuel pressure sensor.
Many modern vehicles have two fuel pumps: a low-pressure fuel pump (LPFP) in the gas tank and a high-pressure fuel pump (HPFP) bolted to the engine.
If there are other error codes for a bad oxygen sensor or bad fuel injector, be sure to do more tests, as they are known to set a P0089 code on some engines.
Possible Causes of a P0089 Code:
Blockage (Clogged Fuel Filter or Restricted fuel lines)
Bad Fuel Pressure Regulator (Pressure Control Valve)
Bad Fuel Pump
Bad Fuel Pressure Sensor

Really good video. I have the p0089 at the moment and now I know where to start looking :)

very informative. thanks

2015 Malibu P0089. Runs fine in city or hwy, but getting off hwy it stalls and takes time to sit before it will start again. How should I diagnose which of these issues is causing the fault? Thank you!

Im having the same issue with my 2015 malibu its showing P0089 its the high rail fuel pressure sensor behind the intake under hood. I'm changing mines Saturday.

Hi did you fix yours? my 2015 malibu just gave me this code aswell

[@RentalCarsandYallCousins]

Did that work? ​@@Jay-n8q

I have a 2004 V70 2.4 non turbo with metal gas tank so no serviceable fuel filter, the pressure sensor at the fuel rail has been changed and so has the fuel pump, so where is the true location of my fuel pressure regulator?? I've read mixed things about locations for it.

I have xc60 2012. P0089 and engine cyl 1 misfire. How did you fix yours?

[@alexperaza2212]

Can me running lean already cause this to happen ?

For the algorithm

Eve po mga sir pag walang code na p0089???
