Check Engine light p0200 injector circuit has popped up on my car about 8 times atleast in the past year, I have no idea what it is, what to look for or how to fix . When it does i put in my $29.99 scanner under the dash and delete the code then I pop the hood and wiggle the injectors and make sure the clips are in.

Im currently running SVO 30 #

""""" The question I sooooooo need help is... what in the hell is a code p0200 what is wrong, what am i looking for. Im hopeing somone does know, has had this code before, has had this code and fixed it cause they new what it was.

Im sorry to post in here but I really need to know what exactley it is in english terms " im not a mechanic" and where the problem is located at or if i need to buy a new part what do i do.

Please help.

Do you have time to do a search? look up p0200, believe me you are not the first person to ever get this code:

Here I even looked some up for you:

If you can get a scanner that can read the GM enhanced parameters, it will tell you which injector has the problem. Referenced Shoebox above.....

I have Autotap and bought the GM Enhanced parameters with it. I'm not sure what type of hand held scanner will do that.....I'm sure one will some where....

 

The code sets for an electrical fault. Key on, check to insure that you have +12V at the pink wire on each of the injector clips. If you don't have 12V on each wire, its either a bad fuse (in that case 4 injectors will not have 12V) or a problem with the pink wire to that specific injector (if only one injector doesn't have 12V).

If you have 12V, with the clips off, measure the resistance of the injector across the two pins on the injector. Should be in the range of 12-15 ohms.

If you've passed all these tests, get a set of 'noid lights, put them on the injectors, and with the engine running, verify that they are all flashing, indicating the PCM is providing the ground that fires the injector.

Could have had this answer if you just posted here in the first place, instead of having one of the owner's of the board move your 1st post out of the Lounge, then having him delete your repeat post in the Lounge, then posting a 3rd time even after everyone told you it was posted in the wrong forum. Posting tech questions in the Lounge is not likely to get you answers.
