Lack of engine power and code P0089

More than likely you have an issue with the high pressure fuel volume regulator. Basically this controls the amount of fuel that is used by the high pressure side of your engine.

I attached the info below on this sensor but here are a few guides that will help with this issue. As you will see, fuel is mentioned in these and so we are going to have to find out why you are loosing fuel pressure and setting this code.

In order to find this we are going to have to start with checking the fuel pressure and that process is below as well.

Please let us know what you find with this and we can go from there. Thanks

Hello,

Can you confirm the production date. I'm only showing rangers up to 2011?

Okay. That means this vehicle is outside the USA? If that is the case then we don't have a manual for this engine as it is not offered here. However, that code on diesels normal means that you have a fuel volume issue which is creating a pressure issue.

So this means we either have a restriction in system like a clogged filter, weak lift pump, or an internal leak allowing too much fuel back to the tank which creates low pressure.

The way to find this is to start with checking fuel pressure and more then likely you have sensors on the rail that will tell you what the PCM is commanding for fuel pressure, called set point pressure. Then you have the actual pressure and these should be about the same. The actual is going to trail the set point slightly as you rev the engine.

This will tell us what the potential issue is depending on what the pressure is doing. Hopefully you have a scan tool that can monitor this. Let us know what you find with this and we can go from there. Thanks
