thanks ill do that tomorrow and see how it goes

2006 duramax diesel my edge juice shows po621 and po403 what are they and what do i do reset it on the edge controler or what no service engine light came on thanks

Don't worry about the P0621- Generator L-Terminal Circuit

The P0403 is an EGR code- Exhaust Gas Recirculation (EGR) Solenoid Control Circuit If you changed your exhaust or deleted your Cat, this code will sometimes pop up, BUT in '06 a lot of EGR valves have been know to take a dump, so that could be it too.

DTC codes P0089 & P0380
 

I need help with there two codes. P0089 started about two months ago and I noticed a slight surge in the ideling. The P0380 started recently started. Please can someone help??
My Mechanic up and moved so I'm out of luck and getting ready to move bak to Texas and tow a trailer full of tools.

P0089 - is Fuel Pressure Regulator Performance

P0380 is Glowplug/Heater Circuit "A" Malfunction

Off the top of my head, Im not sure on how to correct either of them. You might try to clear the codes if you have a programmer or by disconnecting the battery for a bit. I will try to find some information on these codes for ya. Have you done anything to your truck, like any modifications?
