p0101, p0205, p0305?

**Knightmare** · 10-10-2011

Hi, so I finally got my GTP back together..but it's throwing these codes...the SES light is solid under 30Mph and flashes when I get above that...I know that one of the codes is for a miss on cylinder 5...what could be causing it? thanks

p0101, p0205, p0305P0305 is a misfire for Cylinder #5 like you said.
P0101 is Mass Air Flow (MAF) Circuit Range/Performance Problem
P0205 is Cylinder 5 Injector Circuit Malfunction

i would check that injector and make sure it is connected and there are crossed wires or something wrong there. id also check the wires for the MAF as that is your other code

thanks phoenix...gonna go check it out now....could the injector be the reason for the misfire?

deff

**Knightmare** · 10-10-2011

ok thanks gonna go check it out

**Knightmare** · 10-10-2011

ok..so as far as i can tell......the injector is seated fine....plug is fine.....maf plug seemed ok...

maybe i should find someone with more knowledge than myself lol

Or ask questions and learn more to be more knowledgeable.

Sometimes it just takes trial and error...LOTS of knowledge on these forums :> Ask away!

Swap the injector over and see if the misfire follows the injector...if it does, then you have a bum injector.

@billboost-I do ask questions lol, that's why the thread is here

@I800Collect- I plan on asking as many as needed

@bluegtp91- That sounds like a good idea

will def try it..gonna suck though, I dont have a code reader, so gotta swap and run to autozone

if youve got a voltmeter that will read resistance take a measurement of the injector on cyl.5. when mine went bad it did the same thing, checked resistances between a couple injectors and found it was way low. the ranges of the good injectors were around 11.2-11.6 ohms.
