Check for exhaust leaks and turbo intake piping leaks causing low boost pressure. If okay, inspect the turbo for problems. Let me know

fault code 3711-31 piping is fine
Technician: Daniel Wilson,

Check out the entire air supply circuit to the ARD head or for a leaking/faulty mass air flow sensor located on the passenger side of the engine. Follow the tube from the ARD head to the sensor and the combustion air valve. There's two smal lines that connect the sensor and supply tube. They are known to fail but there is no real test to test them and the only way to check is to replace them unfortunately.

ran the ard ignition test with laptop and it failed do you think it could be the ard head we have replaced several of them
Technician: Daniel Wilson,

Yes it very well could be a failed ARD head. Common failure.

Thanks for the update. Have you eliminated all other possibilities for certain that I have already posted?

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 5 years ago
no exhaust leaks and no intake leaks
Technician: Daniel Wilson,
 replied 5 years ago

The MAF sensor is okay and the tubes have been replaced? If all checks okay I recommend an ECM reflash and update and see if the fault code still exists. Let me know
