Cummins ISX 15 power loss no codes 

Just remember that any sensor that has to do with fuel pressure or a fuel ratio like the ones you mentioned will give you power loss. Cummins has high and low fuel pressure sensors that if bad will derate your engine. Another tip if your cam or crank sensor are going out the issue will be intermittently it comes and goes. Also if you go to start your truck and your tachometer is not moving while you start your truck then it might be a possibility that your crank sensor could be shot or a ecm fuse blown. Just thought to add that in there

Some heroes don't wear capes 👏 thank you Sir

Si algun mecánico como yo vio este conpleto sabe que perdida de fuerza sin codigo una se las causa son: Áir charger cooler roto, bosh pressure sensor tapado de ash, los clapms de las mangueras que salen del turbo y entran al intake. Áirr de filtro tapado etc...los sensores que no esté leyendo correctamente dan código

Brother,u are truly blessing.thank you

You truly helped me out Bro. Thanks

Helluva video thank you, I’ve been looking for that ambient air pressure sensor for about a year, thank you

Great video. Good to know about these sensors because I just repaired a turbo speed sensor wire and and a plugged IMAP sensor. These are good to replace per maintenance every 100k miles as well.

Thank u brother I needed this info

Great info. I have a derate for spn1172 fmi2 turpo inlet temp sensor. Dealers are closed on labor day today so i cant find a part. I have 400 miles to go today and it keepts derating and then gping back to normal. Just trying to make this delivery on time. Hope it doesnt shut me down. 🤞

one of the best video...

Appreciate you much.

Awesome video!

Good job driver thank you

Good Intel, thanks.

Need to post OHM for each one. Throwing parts and guessing is expensive

My Cummins started losing power last night! I’m stuck at the truck stop Gurdon,AR. 😫

Thank you!

Thanks !!!

What can cause pressure drop in the fuel rail? I’ve already swapped out the fuel rail pressure relieve valve. No codes but pressure in the fuel rail still dropping from 29k psi to 160 when I shut the engine

Thank you sir

The sensor on the side of the filter housing is the crankcase pressure sensor not position sensor

What year is that motor? 2250 or 2350? Hard to tell in the video.

Very good

power lose in the turbo also ? I'm getting only 23 psi of turbo boost

I have 0 turbo psi, it was working good earlier. Just happened after I turned the truck off. What could it be?

It was my intake manifold temperature sensor

With all those sensors, how you know which one is bad?? Can’t possibly replace them all

Loss of ignition power to the engine could cause a loss of power too. Fuel metering valve. bad ECM. If you don’t mind loading up the parts cannon and just replacing stuff. Best thing to actually do is log data with insite, get it to act up, have a cummins expert like me or at a dealership review the log file to pinpoint exactly what sensor is showing improper data. At least at a dealer if they don’t have a tech that can review the log file, they can send it to cummins for review by a level 2 expert.

I have a 2000 Freightliner FL70 with an 8.3 ISC Cummins with the CAPs fuel pump system. And I have power loss...I wonder if I have those same sensor's on my engine🤔

Using cleaner on a sensor causes it to foul quicker the next time. Use a clean, dry brush to clean it.

I seem to loose a bit of power when accelerating on up hills or when almost stopping and I start accelerating almost at the next shifting of gear it almost seems like it wants to choke not a mechanic and looking to get some guidance on what it might be any help/advice would be appreciated thanks

My truck is a Isuzu prime mover Exz engine number 6wh1 tc 417126.. My truck vibrates heavely when it's running on ideal and when I'm driving with heavy load it also vibrates and also looses big power in the engine when I try to speed up to 20kilometer it looses power so I really don't know what's the problem

Atmospheric pressure was my issue

Nice video , my problem is that is trying lot of black smoke last code was EMP sensor I do have DEf working any idea

I have a 2009 KW w900 when i press the throttle it revives up then lose power ?

My truck is running sluggish.. loss of power and when I'm loaded and take off normal I get gray smoked but if I'm climbing a hill and got to put a pressure to it it turns black, any ideas

Cummins insight will tell me any issue with any one of those sensors. I have yet to see one of those sensors fail or wiring issue without a code. That's not to say it doesn't happen. I'm sure it can. I'm chasing a bug on a DD13 right now. No code, throttle response goes dead only in high range. That's gotta wait now though, -30 cold snap breaks lots of shit in a fleet.

Applies to isl too? 8.9

Having these troubles, only mean, you have a failed EGR cooler

Buy a Detroit instead is all I hear 😂

That was absolutely no help

Maybe the barometric pressure sensor in the fuel pump?

The barometric pressure sensor WILL cause the engine to derate itself... Just a thought.. good luck with it.. ANOTHER Cummins gremlin rearing it's head 🤷

Thank you sir
