chvydmx 03-17-2005, 06:31 PM Anyone know what the codes are??? I recieved my Hypertech today and it found these 6 DTC's P0401 P0404 P1223 P1226 P1241 P1244 Hypertech says I should know what they are before clearing them. THanks Steve Max Power 03-17-2005, 06:44 PM http://www.dieselplace.com/forum/showthread.php?t=22718 chvydmx 03-17-2005, 06:46 PM I found them on the web, now what do they mean and should I be taken it to the stealer to have them look into it? P0401 Exhaust Gas Recirculation Flow Insufficient Detected P0404 Exhaust Gas Recirculation Circuit Range/Performance P1223 Pedal Demand Sensor B Circuit High Input P1226 Control Sleeve Sensor Malfunction P1241 Sensor Power Supply Low Input P1244 Alternator Load Input Failed High BTW here is a website that lists all the DTC codes, I am not sure if these apply to all vehicals or not but take a look. http://www.skpang.co.uk/dtc_list.htm Max Power 03-17-2005, 06:48 PM DTC P0401 - Exhaust Gas Recirculation (EGR) Flow Insufficient DTC P0404 - Exhaust Gas Recirculation (EGR) Open Position Performance DTC P1223 - Injector Output Circuit DTC P1226 - Injector Output Circuit DTC P1241 - Injector Output Circuit DTC P1244 - Injector Output Circuit It's probably a good idea to not clear them, not install the hypertek tune and go to a dealer. If it did it with the tuner, I would clear them and see if it does it again. If it does do it again, clear them, remove the tune and see if it happens again. If it doesn't happen again, it's a hypertek problem. If it does happen again, It's GM's Problem. chvydmx 03-17-2005, 06:50 PM Thanks Max, The first two regarding EGR were same but the other 4 point to the injector circuits. Looks like a trip to the stealer is in order for tommorrow -:t Just what I need more injector problems..... chvydmx 03-17-2005, 06:52 PM THis was the first attempt with the Hypertech, I have not done anything with it yet other than plug it in and start the process. WHen I recieved the codes I viewed and then exited out. Could these codes be caused by my Juice?? THanks for you input... Steve briano 03-17-2005, 07:00 PM are you flashing the truck with the Juice connected? can you do that? you might try remove the Juice, then flash with hypertech..then reinstall edge. I heard there was an issue with flashing the ECU while edge was connected chvydmx 03-17-2005, 10:19 PM I never actually got to the point where I could flash due to the codes. I am not going to put the Hypertech program onto my truck, I just want the speedo and odometer to show correct values. I will however disconnect the Juice when I get that far.

Thanks Steve actually when you change speedo/tire size with it you will be loading the hypertech program onto your truck...just won't have performance tuning. The hypertech copies your stock program and saves it, then asks you questions and then writes the modified program to the trucks computer. just make sure the edge is disconnected when you try it so there is no chance of bugs. good luck joe496chevy 03-21-2005, 10:17 PM I have a juice in... It randomly pops the 1200 series codes you are talking about. If I take it out it goes away.... someday I have to call edge about this. Maybe the new version juice will correct this. | ||
