Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

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.

GMC 2500 Diesel, reduced engine power??


Just my 2 bits, go through a spring cleaning checklist. Plugs could be fouled up, fuel could be contaminated, you already did the filters. Do you have it chipped or programed? Change the exhaust lately? Do you have the code number? Autozone will scan it for you for free, tell you the code number. Again, just my 2 bits.

2005 silverado 2500 HD Diesel lost power and would not accelerate over 30 mph. Engine would not tack over 2000 rpm in nuteral. Called limp mode. what causes this?


Lots of things can. You need to find out what code you have in it before we could help out.
My shot in the dark at it would be the connectors for the #2 and #7 injectors. They only reason I say that is because that is most common problem with the LLY engine. BUT lots of other things can cause the reduced power light to come on.
