i am having problems with my 2001 dodge ram 1500 last night it started missing really bad so hooked it up to a scanner it came up with p0205 code so I changed the injector then traced all wires and everything was ok but truck still missed then I changed the pcm also the tps but the code keeps coming back and I have a dead miss in the motor what eles could be causing this issue

 

Moving this to the second gen ram tech section for ya.

The code is for a circuit malfunction. Generally it's just a bad injector, but, as you replaced it, that apparently isn't the problem. Was the injector new, or used?? have you ohm checked the injector? Is it getting 12 volts TO the injector?

 

t Hey You I have checked the ohm its a brand new injector I even switched it with the number 3 cylinder to make sure I didn't by a bad injector the code keeps coming back and have a dead miss in the motor rewired the number 5 injector changed the injector changed the pcm and also put a new tps running out of ideas here I even have 2 dodge mechanics puzzled but they are still trying to find what would cause this at first I thought broken valve spring but the code doesn't go with that

 

P0205 Injector #5 Control Circuit

Did you check continuity on the wires from the asd relay(12+ voltage) and to the pcm (- firing signal) from the injector?

 

every thing checks out with the voltage to the injector just drove it down the street and its back fireing and the valves are rattling and sounds like the motor is coming apart but only code p0205 shows up what eles could be causing this code to come up

 

Well, it's annoyed with that injector circuit for some reason..... Did you physically replace the wires for that injector?
