started my work truck the other day (2004 3500 stake bodey) and the instriment panel said service air bag. Drove it down the road about 2 miles and that went away, idle dropped to 450 rpm and truck had no power wouldnt rev up . i limped it back to the shop and put my actron reader on it, had codes p0201, p0206, and another one that i cant remember that was for open circuit on injector group a. cleared the codes and truck has ben running fine any ideas

 

https://www.dieselbombers.com/diesel...ble-codes.html go to this site and click on the code you have and see if that helps and welcome to diesel bombers

 

yeah i know it comes out to a open circuit on injector 1 and open circuit on injector 6 and then the open circuit on injector group a i was thinking that it either had a bad ground or a dirty conection somewhere but i checked today and couldnt find any obvious problems

 

the other one you couldn't remember was it P1262?

heres some info about the code without the flow chart. if it comes back see what the other code was.

CIRCUIT DESCRIPTION
The fuel injection control module (FICM) supplies high voltage to each fuel injector on the ignition voltage circuits. The FICM energizes each fuel injector by grounding the command circuit between the FICM and the fuel injector. The FICM monitors the status of the ignition voltage circuits and the fuel injector command circuits. When a fuel injector circuit condition is detected by the FICM, all of the fuel injectors on the affected ignition voltage circuit will be disabled. If a circuit condition is detected on a fuel injector circuit for cylinders 1, 4, 6, or 7, DTCs P0201, P0204, P0206, P0207 will set, along with DTC P1261. If a circuit condition is detected on a fuel injector circuit for cylinders 2, 3, 5, or 8, DTCs P0202, P0203, P0205, P0208 will set, along with DTC P1262.

CONDITIONS FOR RUNNING THE DTC

• DTCs U1800, and U2104 are not set.
• The engine is running.
• The charging system voltage is between 6-18 volts .

CONDITIONS FOR SETTING THE DTC

• The FICM detects an incorrect current on a fuel injector circuit.
• The condition exists for less than 1 second .

ACTION TAKEN WHEN THE DTC SETS

• The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
• The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC

• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
• Clear the MIL and the DTC with a scan tool.

 

it might be ill have to look at work tomaro i still have the number written down in my tool box
