P0264 code... Cylinder 2 injector circuit low

I just replaced the UVCH's and I'm still getting the P0264 code when I do a buzz test or a KOEO test. What could be the possible causes? A bad solenoid? Bad #2 injector? The engine runs fine right now, no missing that I can notice.

you could have high resistance in the injector solenoid. did you do a cylinder contribution test? a bad wire in the engine wire harness can cause that too,pin out the harness to eliminate that.

I ran the contribution test with AE and it performed successfully.

Mike, I know it is kind of time consuming, but try swapping the injector into another hole, see if the problem follows the injector.

Check the resistance of that solenoid, and if it's the same as the others, swap it with another to see if the code follows.

If not, start pinning out the harness.

Re: P0264 code... Cylinder 2 injector circuit low

Ok guys... Thanks for the ideas. Since this isn't causing me problems right now, I think I'll wait for spring(warmer weather ) and then try swapping injectors/solenoids and see how things go from there.

Dave, can the solenoids be swapped without pulling the injector? Or will I have to go the route Andy mentioned, pulling the whole injector?

Re: P0264 code... Cylinder 2 injector circuit low

you can swap a solenoid without removing the injector.

chances are it is not a bad solenoid, though.

We have an inductance meter, with which we use to check the solenoids... and we have maybe seen 4-5 bad solenoids in the past 5-6 years...tens of thousands of injectors worth.

It is possibly a bad solenoid, and maybe worth swapping on another solenoid for comparison, but we have seen high internal resistance, on the MOSFET drivers within an IDM create similar "bad solenoid" scenarios...so maybe try another IDM if the solenoid swap doesn't fix things.

...or it could be that the armature to solenoid clearances are not 'correct' on that particular injector creating a higher current flow through the IDM...

HEUI's are such lovely little things...

take care~

Re: P0264 code... Cylinder 2 injector circuit low

I had heard that the chance of an injector solenoid going bad was fairly slim. If I can swap one without pulling the injector, I will try that first. Actually, I think I'll just ohm all the solenoids first and see how they compare. What is the desired ohmic value of the injector solenoids?

Re: P0264 code... Cylinder 2 injector circuit low

I can't recall correctly what the ohm value is of a good solenoid, sorry.

But the single bad solenoid that I've found was all black and melted underneath when I took it off, externally it looked fine.

Re: P0264 code... Cylinder 2 injector circuit low

I think all of my old AAs were about 3.2-3.3 ohms...
