All of the piping has to be cleaned up as well.

Another area was the boost and temperature sensors on the driver’s side below the intake throttle and EGR valves. Both were fairly clean so the EGR which is surrounded constantly by hot exhaust gases was the next best choice.

Can a MaxxForce DT diesel engine have no codes?

If a Maxxforce DT diesel engine in our fleet experiences low power with no codes we will be pursuing the same areas we looked at for this fix. As a matter of fact there is another bus in our fleet with similar problems. Experience has paid off once again.

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.

Why did my Maxxforce Engine flip a code?

The on board computer works with percentages when opening and closing the valves on the EGR so one would think that if the program that runs the engine noticed a wrong percentile it would flip a code. Regardless of that the problem got repaired and everybody is happy.
