Is this fuel rail pressure normal?

Is this fuel rail pressure normal? at 700 rpms. DD15. 2017. Thanks!

 

That is almost 7000 psi. Most common rail engines will been around that low end and around 28,000 - 33,000 psi high end. Depends on the engine. Any engine I have seen will have "Fuel rail pressure desired" or something like that show what the ECM is expecting or commanding. Watching desired compared to actual is the best way to know if the pressure you are seeing is normal or not.

 

You need to disclose year and motor for anyone to say.

The paccar mx13 runs at 7k to 30k.
If google is correct.

I don't know about Detroit, cummins or cat.

Thanks. It is a DD15. There is no code nor check engine light. The pressure reads 441 with no issues. I wouldn't know if there is low pressure issues. Any information is appreciated.

 

Top of the screen under the actions tab is a fuel system test,I don’t remember what its called, but it will let you monitor commanded vs actual.

 

What software is that?

 

As @Heavyd stated…..

441 bar is = to about 6396psi

And normal for Idle PSI on any common rail fuel system.

Thanks Goodysnap. I wasn't aware of the bar unit equaling to psi.
