Turbocharger not working on 1998 Dodge Ram Dually 3500 Cummings Diesel

Have a 98 Dodge Ram 3500 Cummings Diesel. The turbocharger is not working. Does anybody have a Skew on how the entire Turbocharger is supposed to be set up from Intake lines/vacuum lines that supply air to the Wastegate. What is the air pressure rating supposed to be for this vacuum air line that connects to the Wastegate. Is there another method for supplying air to the wastegate other than the original vacuum lines going to the Wastegate. I have seen other setups where guys have ran new sources of air supply lines to the wastegate via the Exhaust manifold port. Any ideas on how to get this turbocharger working again.

    The turbo setup on this truck was an out of date fix up by someone who previously owned the truck. The turbo had no intake air line fitting for one. The previous owner had hand picked some vacum line tee;d into another vacum line and figued this would power the waste gate. It was all a complete mess.

SOURCE: turbocharger underboost faulty wastegate bypass regulator

Sounds like a boost leak/vaccuum leak, check all hoses and ensure they are all hooked up well, and there is no leaks or cracks, if you don't find one there is ways to test this.

Need to fix my 2007 Dodge Ram 3500 dually,6.7 Cummings diesel, check engine light code P2002

P2002 - Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
Description: The powertrain control module(PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM. Possible Causes:
  • Dirty air cleaner element
  • Recent manual or thorough diesel particulate filter regeneration
  • Aftermarket accessories and performance modifications
  • Modified tailpipe
  • Exhaust leaks before or near the diesel particulate filter pressure sensor
  • Leaks in the diesel particulate filter pressure sensor connecting hose
  • Damaged diesel particulate filter
Diagnostic Aids: Check for leaks in the exhaust system. Check for aftermarket exhaust accessories and performance modifications that decrease the exhaust restriction. If a new diesel particulate filter was recently installed, verify the diesel particulate filter parameter reset procedure was carried out.

2004.5 dodge 3500 wastegate error code

A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger.

It is not really a minor thing. It may not cause a major problem, but you are very likely loosing power and fuel mileage because of it.
