What to do if your MaxxForce 13 craking but no start?
Verify that the VSS (Vehicle Speed Sensor) is reading smoothly. If the code sets while in motion or during the creep test, replace the VSS. If the code does not set, a case file needs to be submitted to Navistar because the flow chart diagnostics does not continue after that step. There are a lot of extra steps in the diagnostic procedure.
Why does my Maxxforce Engine have a low power tip?
The main cause of this is a plugged up engine crankcase breather. A service kit is available for the MaxxForce DT diesel engines that allows mechanics to disassemble the low pressure and high pressure turbocharger on the compressor side (intake) and remove the soot buildup.
What is the diagnostic code for MaxxForce 13?
I can’t give any diagnostic info without knowing exactly what the code is. It’s the dreaded SPN 731 code but is the FMI 18 or FMI 16. Two different paths for diagnostics depending on the exact fault. You can start blindly throwing parts at it if you want but I doubt you’ll fix it without doing the diagnostics.

May check that. Run an air management test and make sure it passes. Take it for a road test with a second person watching the laptop. Under full load rated speed you should be getting Right now you are at 65 psi of delivery pressure, should be 90. avgdzlmekanic and QUALITYTRUCK Thank this.
What to do if air pressure is not building?
The governor will either be mounted on the side of the air compressor or air dryer. You can try tapping on the side of it to see if the truck will build air. I have had the unloader valve in the compressor go bad, but not very often.
