My bullydog tuner showed me the p0200 injector circuit low,high code but no code for a specific clydiner. My truck doesn't have a rough idle and hasnt stalled. Sometimes while drive you can feel it kick or slow down like it is having a misfire or short somewhere, but no code for a specific cylinder. Haven't really noticed a loss in fuel economy, don't smell fuel, and doesn't seem to smoke a lot just on startup when it is cold. So is there something going on with the PCM or should I test all fuel injectors and look for a short? Never really messed with electronic fuel injection so not sure where to look or test. Any help would be greatly appreciated.

Also the ABS light and parking light come on after driving the truck for a mile or so but still have all breaks. It goes away every time you shut the truck off and comes back on every time you drive it. On the dash it says to Service Brake System. No code appears on the bullydog so I'm curious if it is the ABS module or pump or something else.

 

You need a scan tool that will read B and C codes. A look at misfire history might give a clue on the P0200.

 

I don't have a scan tool. I know autozone and places like that have them . Does there's pickup codes like that?

 

ABS codes are separate from engine codes. You need a scan tool that is capable of reading those codes. It's not un-common for the ABS module to fail or have a grounding issue.

In regards to the Injectors. If you can test them, give it a shot. If not, you may need someone with a dealer type scan tool that can test them for you. Any 1/2 way decent shop should have this capability. This could also be a grounding issue or a fault with the PCM.

 

Yeah I got a friend who runs a shop I could take it to. Just don't wanna spend money on finding out the issue if i could find it myself and go from there. Looks like I'll be heading to autozone in the AM to find out what's all going on

 

When I bought the truck it came with a bullydog gt tuner. Can I just remove that cable from the obd-2 port or will it damage the computer?

 

It should not. I have never used one so I am not sure if it uploaded a tune or if it's just being used as a gauge to monitor things.
