Why does my Cummins ISX low boost high exhaust temps?
If you run down south for the week, truck will no due this all week come north and it will do this all the time. 35 degrees or less and it does it. Changed out Exhaust gas pressure sensor, did not fix. Any ideas? check the turbo see if the shaft rocks enough to hit the housing also check the boost sensor see if its plugging up
What are the problems with a 2009 Cummins ISX?
The truck is doing the exact same thing, it doesn’t run any better or any worse than it did BEFORE I brought it in. Thanks for the info. 111 – coolant, 131 is a short in the accelerator, 27 seems to be an actuator issue with the VGT turbo, 384 I can’t find, and 131 comes back to an issue for the EGR pressure sensor.
What’s the exhaust temp on a 2006 Cummins?
I have a 2006 ISX cummins 530 hp with 433,000 miles on it. It is an EGR motor. Problem is lately since weather has started to cool up motor will sometimes loss boost of about 10 lbs and exhaust temp will climb to 1000 to 1100 degrees. You might drive 5 miles and it comes out of it.
Can a Cummins diesel run in cool weather?
Truck continues to due this in cool weather. If you run down south for the week, truck will no due this all week come north and it will do this all the time. 35 degrees or less and it does it. Changed out Exhaust gas pressure sensor, did not fix.
How to fix a Cummins ISX air compressor problem?
Spray liberal amount of WD40 into air pressure governor . Put some rug over compressor discharge opening . Safety glasses is ON !!!!!!!!!!!! Start engine and spray WD-40 into pumping compressor until carbon deposits are washed from the valve. serozhah and blr300 Thank this.
Where are the vanes on a Cummins ISX?
In the 2nd video, you can see the turbine housing. The vanes on the turbine wheel fit in the slots of the rotating collar in the turbine housing at the left. If those slots fill with soot, the that collar can stick as well. Everything can be cleaned, but the dealers pretty much just replace them under warranty.
Why does my Cummins ISX have a sliding collar?
Click to expand… If the one on the ISX is built like the HE351VE used on the 6.7L Cummins in the Ram trucks, it is a sliding collar that changes the geometry of the turbine housing. The soot can build up in the moving parts and the actuator can’t move it properly.
What should the Regen temps be on a Cummins Engine?
Intake manifold pressure – 10-14″ Hg – Low could indicate boost or air to air leaks. Percent load – less than 2% (with the fan off) I’ve seen most regens fail with this at 5% or higher. This is also what is near 0% with a cold engine and 5-7% with a hot engine. Typically a weak metering actuator, the engine heat makes the actuator weak.
When to close the EGR valve on a Cummins ISX?
If the temps reach 525 or better and the inlet temp to the DPF stalls around 800 or is very very slow to reach 1000+ then something is wrong with the injector or DOC. Monitor these parameters during a regen, and you should have these values; EGR valve position – 0% – EGR valve must be closed.
