No Power!!!! Running On Four Cylinders
My truck fell flat on its face today, I "Limped" home and retrieved these codes with my predator,
Po202 Injector circuit malfunction cylinder #2 Po203 " " " " #3 Po205 " " " " #5 Po208 " " " " #8 Po522 P2149 nd064 Is this something I can fix myself, Or should I take it to the dealer? Thanks in advance, John |
They all seem to be circuits/sensors Low Voltage ect
Did you jump some one recently or weld on the truck ? Maybe ECM/PCM Malfunction Reset codes and disconnect batteries for a hour then reconnect and start it up and see if it throws codes DM |
p0522 is power steering pressure sensor circuit low input
p2149 injector positive voltage control circuit group 2 (GM) sounds perty drastic to me..... what year is the truck? is it under warranty? |
there are 2 wiring harnesses, one going to each bank of cylinders, check them for fraying, cuts or abrasions, typical duramax problem.
|
Thanks guys, I did a search on another forum, Aparrently there is a problem with the wiring harness on these trucks. I will take it to the dealer tomorrow.
|
John, I will call you in a few minutes. I've been teaching a class and just got done thats why I couldnt answer the phone. There are far more than two harnesses on the DMax for each bank. I'll call in a minute and help you through it.
|
Thanks Tracy!
|
John, something else I thought of...go through 10 key cycles and see what codes clear.
