at idle is 7-10 Lbs
at 1800 RPM, is 35-42 Lbs
The normal idle oil pressure for an N14 Cummins engine typically ranges from 10 to 20 psi (pounds per square inch). At higher RPMs, the oil pressure can increase significantly, often exceeding 40 psi. It's important to ensure that the oil pressure remains within this range to prevent potential engine damage. Always refer to the specific engine manual for precise specifications.
1400 - 1450 RPMs.
Some vehicles` oil pressure will do this when at an idle. This is normal, if the oil pressure does not get higher when at higher rpms then something may be wrong.
No less then 6 PSI. At 1000 RPMs. 18 PSI. are more at 2000 RPMs. 24 PSI. are more at 4000 RPMs. And that is factory specs.
You need 10psi for every 1000 rpms That’s perfectly fine oil pressure
Oil pressure ( minimum amount ) is 6 LBS. at 1000 RPMs. 18 LBS. at 2000 RPMs. 24 LBS. at 4000 RPMs. more pressure is fine too.
With this kind of question you need to check for electrical problems. Hook up a manual gauge and see it you have the same readings. If so you have internal engine problems. If not it's electrical.
If you have an engine that idles at 6000 rpms, you need to have it checked - immediately. Around 750 rpms would be normal.
800 rpm normal temperature
Oil pressure ( Minimum ) 1000 RPMs 6 LBS 2000 RPMs 18 LBS 4000 RPMs 24 LBS It must have at least that much oil pressure at these different RPMs to LUBE the engine. If it has 80 LBS are more then the oil pump check valve is not working correctly
I don't own a 2001 Cummins engine anymore, but when I did, it was a Signature 600, rated at 600 horsepower at 2100 RPMs. Your 2001, we can't say without knowing the model of engine you have.
Advertised engine oil pressure is: 1000 RPMs----6 LBS or more 2000 RPMs-----18 LBS. are higher
