Cat c15 Atmospheric pressure sensor

[@bobbytarte2299]

I'm a cat man and I thought I knew everything til I watched your vids. Keep posting I love your videos. They are direct and very informative.

Bobby Tarte Thank you .I’m still working on it trying to improve fuel mileage my goal is to get 7 miles to the gallon to pull cows🐄

Thank you !!! I have 3406E model and I been watching your videos and learn a lot about Cat engine !!! Thx again...

thanks. this video is very very amazing and informative very helpful. thanks again

The C-12 atmospheric sensor is in a real handy spot… just changed one out

[@screamingeagle9553]

Came across your video a few weeks ago and just today I bought this sensor and o-ring from KW and was $250. I hope I can tell the difference on my next trip out. I took my truck out last week for the first time and seemed to idle/run fine but with a load going up a steep hill it shimmied a little. I also noticed my pyro getting up to 1000 degrees really easy so I found out my exhaust was almost clogged so I straight piped it and seems to breathe better. Hope this sensor will help too. Will update!

[@arsentrucking7883]

Pretty soon I have to record another video regarding accert cat. A lot of people been asking me some random questions I didn’t realize how Popular this video would become😃

[@screamingeagle9553]

@@arsentrucking7883 yes sir! I’m excited to try this out. I hit the road Monday doing the exact same route so I should be able to feel the difference. I found location very easily. I asked my mechanic about this sensor and he didn’t know anything and/or symptoms about it. They are just like what you stated in your other video about if there is no light then there nothing wrong. Thank your time for your video. My first semi and cat so I’m trying to learn everything I can about it.

I have a 5ek that's been running funny. But one of my wierd symptoms is the water temp is erratic on the ecm sensor. Replaced the temp sensor twice but notice it makes a difference at what altitude im at. I also replaced the wiring harness. All started after overhauling

[@spudbuilt]

I keep getting temp sensor code also. Did you figure out the problem?

[@Turboboob]

What overhaul kit did you buy? Cat stuff or aftermarket?

[@geurisesquea1698]

I ran to a similar problem when my engine need to produce torque it was giving me low power. Well it was the injectors o rings

[@joebaeza86]

Part # is : 274-6717 - sensor 214-7568 - O-Ring

[@Flyoklahoma10]

Can you add part# for just the Onring please. Thanks

[@yvetteramirez1508]

Thanks for your video. My CAT C15 6NZ barometric pressure sensor is set by Default and reading a constant 14-15 via CAT ET Software. The truck lacks power on a loaded takeoff, other than that no other noticeable difference. I replaced the sensor with a New One, no change. Also no way to check the sensor by a ohm test. If anyone reading this can give me a insight I and everyone reading this would appreciate your knowledge...

[@HIGHENDMUSIC_6]

No, it’s not work so then I go to mechanic again he go through everything step by step then he find the problem in fuel which line come from injector to back fuel tank they have air in the fuel lines which is reverse line they he take off the air from the ball joint underneath the bank which connect both fuel tank then he shut off passenger side tank , now problem is solved he suggest me put a new ball joint at the time they don’t have in stock . Before I spend to much money on the motor Cat dealership told me you can change your ecm they problem even cat dealership can’t find the problem , if you want the name of the mechanic ask me

@arsentrucking I’ve got a c15 that starts right up, runs for 40 seconds and shuts off. Starts right back up, idles good but won’t run for more than 40 seconds each time. Oil pressure is higher than normal around 80-90 when it normally runs 60 or so at idle. When I unplug the atmospheric pressure sensor the oil pressure is at normal pressure but only runs for 10 seconds or so. Please help

My 6NZ stumbles when applying fuel gently in high elevations or during low oxygen days. Even after fuel filter changes. Its been idling rough as of late. Its not throwing any codes. Just does not respond at the begining of fuel peddle pressure. Sometimes it will cut out. Alway thought it might have to do with barometric pressure. I guess ill try it. Thanx👍
