had a charge air test today,,, no leaks,,, Im thinking now the turbo is not working proper,,,, on the road relay 4 I get a code 411 any one know what a code 411 is ?
-
if your loosing coolant and its not leaking externally than you might have leaking EGR cooler, thats why your mpg is bad.
can you get full code from dash? also year and ESN -
Also I don't know about egr systems but they put a new egr valve on when they prepped the truck for sale would the egr cooler be a separate issue from the egr valve? -
a non working vgt will produce 20 lbs boost at the most, one way to see if its working on the turbo with the engine running and aired up the actuator rod should be pushing the little arm downward and come up when engine is off. you mentioned check engine faults, do you have a SID 27 code by chance?
-
Is there a way I can bring up any faults the engine may have had recently? -
idk the peterbilt way of viewing faults, any shop with Cummins Insite should be able to pull the active/inactive codes for you and 1/8th inch doesn't sound much, this link shows how you can test it tho. http://bigrigshots.com/category/isx/
